Ophioceras freycinetiae is the first asexual morph linked to the genus. It is closely related to O. chiangdaoense and O. leptosporum, which are known only from their sexual morphs, thus precluding a morphological comparison. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Pestalotiopsis mangifolia (voucher INBio:612E, GenBank KU204609.1; Identities = 519/546 (95 %), five gaps (0 %)), Ophioceras sp.

Cadophora neoregeliae Crous, sp. nov. Etymology. Name refers to the host genus Neoregelia from which it was isolated. Classification — Ploettnerulaceae, Helotiales, Leotiomy- cetes. Mycelium consisting of hyaline, smooth, septate, branched, 2–3 µm diam hyphae. Conidiophores hyaline, smooth, erect, penicillate (at times reduced to solitary phialides on hyphae), branched or not, with clusters of conidiogenous cells, terminal and intercalary, 30–90 × 2–3 µm, 2–7-septate. Conidiogenous cells hyaline, smooth, curved, phialidic, 7–15 × 2.5–3 µm, with visible periclinal thickening, arranged in rosettes of up to seven per conidiophore, mostly terminal. Conidia solitary, aseptate, globose, guttulate to granular, smooth, hyaline, 2.5–4 µm diam. Chlamydospores rare, terminal on hyphae, ellipsoid to subglo- bose, brown, smooth, guttulate, 8–12 × 6–8 µm. Culture characteristics — Colonies flat, spreading, with sparse aerial mycelium and smooth, lobate margin, reaching 50 mm diam after 2 wk at 25 °C.

Notes — Species of Cadophora (dematiaceous hyphomy- cetes with monophialidic conidiophores with distinct flask- shaped, hyaline collarettes, and aseptate conidia) are common- ly isolated from soil, but are also known as plant pathogens or saprobes (Bien & Damm 2020, Crous et al. 2020b). Cadophora neoregeliae is distinguished from other species known in the genus by its globose conidia, 2.5–4 µm diam, and the produc- tion of chlamydospores in culture. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had high- est similarity to Cadophora fastigiata (strain CBS 869.69, GenBank MH859469.1; Identities = 554/569 (97 %), no gaps), Phialophora dancoi (strain IFM 50357, GenBank AB190869.1; Identities = 551/566 (97 %), no gaps) and Cadophora malo- rum (strain NW-FVA5175, GenBank MT561395.1; Identities = 563/579 (97 %), one gap (0 %)).

Notes — Phaeosphaeria (based on P. oryzae) has Phaeo- septoria asexual morphs (Quaedvlieg et al. 2013). Several spe- cies of Phaeosphaeria occurring on Carex mainly from Europe and North America were treated by Shoemaker & Babcock (1989), but these are all known from their sexual morphs, making it impossible to make a morphological comparison with the asexual P. caricis-sectae, which occurs on Carex secta, a host endemic to New Zealand. Three species of Phaeoseptoria are known from Carex, namely P. caricis (conidia 70–80 × 7 µm, 7–10-septate), P. caricicola (conidia 35–55 × 4 µm, 7-septate) and P. festucae (conidia 50–85 × 2.8–4.8 µm, 8–11-septate (Erdoğdu & Özbek 2017), which are clearly distinct from P. caricis- sectae.

Notes — Cladophialophora is characterised by aseptate, ellipsoidal to fusoid conidia arising through blastic, acropetal conidiogenesis, and arranged in branched chains (Badali et al. 2008). The conidial scars are thickened and darkened, but not refractive. Cladophialophora behniae is related to C. scil- lae (CBS 116461, on Scilla peruviana, New Zealand, conidia (5–)10–20(–35) × 1.5–3 μm, 0–1(–3)-septate; Crous et al. 2007d) but can be distinguished from the latter species based on conidium morphology.

Notes — Colletotrichum cliviigenum is accommodated in the C. boninense species complex (Damm et al. 2012b). Several species are known from Clivia, namely C. cliviae (conidia 23–28 × 5–7 μm, the Netherlands), C. cliviicola (conidia (11–)15.5– 20.5(–26.5) × (4–)5.5–6.5(–7) μm, China), and C. himantophylli (conidia 14–24 × 4–4.5 μm, Czech Republic) (Damm et al. 2019). Colletotrichum cliviigenum can be distinguished from those species in having larger conidia.

Notes — Falcocladium heteropyxidicola is related to F. thai- landicum (vesicles sphaeropedunculate, conidia (19–)20–23 (–24) × 1.5(–2) μm; Crous et al. 2007b, Lombard et al. 2015), but is distinguished from that species by its globose vesicles, and smaller conidia. (notes Falcocladium heteropyxidicola continues on Supplementary material page FP1192 & 1193) Etymology. Name refers to the host genus Senegalia from which it was isolated. Classification — Castanediellaceae, Xylariales, Sordario- mycetes. Observed to form cupulate conidiomata (satchmopsis-like) on host tissue, but in culture these were weakly developed, 40–100 µm diam, brown, arising from a reduced stroma, with brown, cupu- late basal layer giving rise to a dense layer of brown cells that terminate in densely packed, brown, ampulliform conidiogenous cells, 5–8 × 2.5–3 µm, that line the inner layer of the cupulate or sporodochial conidioma, polyblastic with minute unthickened denticles at apex. Conidia solitary, aggregated in clusters in buff mucoid mass, hyaline, smooth, granular, falcate, fusoid, aseptate, widest in middle, ends subobtuse, (9–)10–11(–13) × 1.5(–2) µm. Culture characteristics — Colonies flat, spreading, with mo derate aerial mycelium and smooth, even margin, reaching 16 mm diam after 2 wk at 25 °C. On MEA surface and reverse hazel; on PDA surface smoke grey, reverse hazel; on OA sur- face bay. Typus.

Notes — Castanediella is characterized by macronematous, mononematous or sporodochial, branched, brown to pale brown conidiophores, with monoblastic or polyblastic, sympo- dial, discrete, cylindrical to lageniform, hyaline to subhyaline conidio genous cells, and septate, cylindrical to fusoid, hyaline conidia (Crous et al. 2015a, 2021, Hernández-Restrepo et al. 2017). Castanediella senegaliae is related to C. ambae (see FP1230 in this paper), which has erect, sporodochial conidio- mata, similar to those observed in C. senegaliae, which also appear cupulate. Furthermore, it appears that Synnemadiella eucalypti (synnemata with phialidic conidiogenous cells and ellipsoid, inequilateral, aseptate conidia; Crous et al. 2016) clusters among species of Castanediella, suggesting that this complex requires revision.

Etymology. Name refers to the host genus Euphorbia from which it was isolated. Conidiophores macronematous, mononematous, erect, solitary or in groups, mostly unbranched, thick- and smooth- walled, hyaline to pale olivaceous brown, 70–120 × 3–4 µm, 1–2-septate, with 4–6 conidiogenous cells arranged in a cluster at apex. Conidiogenous cells phialidic, clavate to fusoid or elongate doliiform, hyaline, becoming olivaceous brown and verruculose with inconspicuous collarettes, 7–11 × 3–5 µm. Conidia in a mucoid droplet, aseptate, olivaceous brown to dark brown, smooth, becoming verruculose, thick-walled, guttulate, fusoid, with rounded apex and truncate base, (7.5–)8–9(–10) × (3–)3.5–4 µm; rarely subcylindrical, up to 17 µm long. Ger- minating conidia dark brown, verrucose, 1-septate (constricted at septum) with polar germination, 13–17 × 6–7 µm. Culture characteristics — Colonies erumpent, spreading, surface folded, with moderate aerial mycelium and smooth, lobate margin, reaching 8 mm diam after 2 wk at 25 °C. On MEA surface saffron, margin umber, reverse umber; on PDA surface and reverse pale luteous; on OA surface iron-grey with buff margins. Typus.

Notes — Lombard et al. (2016) distinguished several genera in Stachybotryaceae. Paracymostachys can be distinguished from Cymostachys by having smooth, primarily unbranched conidiophores, and fusoid, rarely subcylindrical conidia. Para- cymostachys euphorbiae is distinct from Cymostachys species in not having fabiform to globose conidia. Furthermore, it is distinct from S. limonispora (conidia (6–)6.5–7.5(–9) × 3–4 μm) in lacking limoniform conidia, and from S. phaeophialis (conidia ellipsoidal to fusoid) in having larger conidia ((6–)6.5–7.5(–9) × 3–4 μm; Lombard et al. 2016).

Notes — Crous et al. (2007a) introduced the genus Toxico- cladosporium to accommodate cladosporium-like fungi with distinct, dark, thick-walled conidial septa, and lacking the typical coronate Cladosporium scar type. Toxicocladosporium ptero- carpi is related to T. chlamydosporum (on Eucalyptus camal- dulensis, Madagascar; terminal conidia 6–7(–9) × 2.5(–3) μm, forming chlamydospores in culture; Crous et al. 2009), from which it is morphologically distinct. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence had highest similarity to Toxicocladosporium chlamydosporum (strain CBS 124159, GenBank MH863361.1; Identities = 545/549 (99 %), no gaps), Toxicocladosporium protearum (strain CBS 126499, GenBank NR_152321.1; Identities = 541/545 (99 %), one gap (0 %)) and Toxicocladosporium velox (strain CBS 124159, GenBank NR_155890.1; Identities = 518/522 (99 %), no gaps).

Etymology. Name refers to the host genus Dalbergia from which it was isolated. Classification — Diatrypaceae, Xylariales, Sordariomycetes. Ascomata brown, erumpent, in tight clusters on host tissue, punctiform with elongated neck, 200–500 µm diam; ascomata overmature, asci and ascospores not seen. On PNA: Conidio- mata pycnidial, immersed, brown, subglobose, 200–300 µm diam; wall of 3–4 layers of pale brown textura angularis. Coni- diophores hyaline, smooth, subcylindrical, branched, 1–4-sep- tate, 20–40 × 2–3 µm. Conidiogenous cells hyaline, smooth, subcylindrical with slight apical taper, phialidic, apex 1 µm diam, lacking flared collarette, 12–20 × 2–2.5 µm. Conidia solitary, hyaline, smooth, aseptate, sickle-shaped, widest in middle, apex subobtuse, base truncate, (15–)18–22(–25) × 1.5(–2) µm.

Notes — The phylogeny of the Diatrypaceae requires revi- sion, as the present phylogeny does not correlate with the morphology (De Almeida et al. 2018). Diatrype dalbergiae is only known from its asexual morph, making a comparison with sexual morphs impossible. Based on its similarity to known species such as D. disciformis and D. palmicola, it is therefore placed in the genus Diatrype. Colour illustrations. Dalbergia armata.

Etymology. Name refers to the host genus Dalbergia from which it was isolated. Classification — Sporidesmiaceae, Sporidesmiales, Sorda- riomycetes. Mycelium consisting of septate, branched, hyaline to pale brown, smooth, 1.5–3 µm diam hyphae. Conidiophores micro- nematous, erect, solitary or aggregated, inconspicuous, subcy- lindrical, forming from superficial hyphae, hyaline to pale brown, smooth, unbranched, 3–8-septate, 50–120 × 2.5–3 µm. Coni- diogenous cells integrated, terminal, monoblastic, subcylindri- cal, hyaline to pale brown, smooth, 15–30 × 3–4 µm, forming unbranched conidial chains; loci 1 µm diam, not thickened nor darkened. Conidia in unbranched, dry chains, acrogenous, acropetal, in long flexuous chains, subcylindrical, ends sub- obtuse, thick-walled, guttulate, hyaline becoming medium brown, smooth, (1–)2(–4)-distoseptate, (17–)23–31(–48) × (5–)6–6.5(–7) µm; scars 1 µm diam, not thickened nor dark- ened; conidia attached via narrow isthmus, thus frequently remaining attached for long periods.

Notes — Morgan-Jones (1975) established Lylea with L. catenulata as the type species. Lylea is characterised by forming catenate, distoseptate conidia on monoblastic conidio- genous cells. Lylea dalbergiae is related to L. tetracoila (conidia 3–4-distoseptate, (17.5–)20–40(–65) × (3–)4–5.5(–7) µm; Holubová-Jechová 1978), but distinct in that it has shorter co- nidia. It is also distinct from other species in the genus (Xia et al. 2014). Lylea dalbergiae was isolated as a mycophylic fungus, growing on ascomata of Diatrype dalbergiae (see FP1198 on top of this page) on bark of Dalbergia armata.

Notes — Bezerromyces gobabebensis clusters as a new species sister to a clade along with Xiliomyces brasiliensis (sterile Dothideomycetes) and species of Bezerromyces (Bezerra et al. 2017). Based on these data, and the morphology of B. gobabebensis, we have chosen to expand the circumscrip- tion of Bezerromyces to also include the genus Xiliomyces. A new name is proposed below, because the epithet brasiliensis is already occupied. Bezerromyces pseudobrasiliensis Crous, nom. nov. Myco- Bank MB 839515 Basionym. Xiliomyces brasiliensis J.D.P.

Etymology. Isolated from dung of Procavia capensis (rock rabbit). Classification — Sporormiaceae, Pleosporales, Dothideo- mycetes. Ascomata pseudothecial, globose to pyriform, 200–300 µm diam, smooth, black, central ostiolata; wall of 6–8 layers of brown textura angularis. Pseudoparaphyses filiform, hyaline, smooth, 3–4 µm diam, anastomosing, constricted at septa, hyphae-like. Asci 8-spored, bitunicate, cylindrical-clavate, stipi- tate, with ocular chamber, 85–170 × 20–25 µm. Ascospores biseriate, cylindrical with obtuse ends, becoming dark brown, guttulate, transversely 3-septate, prominently constricted at septa, two middle cells equal in length, 7.5–9 µm long, end cells 11–14 µm long; germ slits oblique, gelatinous sheath not persistent, (32–)35–40(–42) × (7–)8–9 µm.

Notes — Preussia procaviicola was isolated from the same dung sample as P. procaviae (Crous et al. 2020a), although the latter is only known from its asexual morph. Preussia proca- viicola is close to P. intermedia (ascospores 3-septate, 48–59 × 9.5–11.5 µm; Guarro et al. 2012), but morphologically distinct from that species.

Notes — When freshly collected leaves colonised by Neo- chaetothyrina syzygii are incubated in moist chambers, asco- mata develop within 1 wk. However, the upper wall is a cover- ing membrane of hyphae, that easily separates during slide preparation, leaving a layer of near naked asci embedded in a brown mucilaginous mass. Neochaetothyrina is reminiscent of Chaetothyrina (Hongsanan et al. 2017), but the latter species lacks superficial hyphae and setae. Neochaetothyrina syzygii was also compared to Chaetothyrium syzygii (on Syzygium cordatum, Kwazulu-Natal, PREM 33103), but the latter had hyaline, fusoid ascospores that become brown and 3-septate at maturity, 20 × 6–7 µm. Furthermore, Asterina syzygii (on Syzygium gerrardi, Woodbush, Limpopo Province, PREM 17755) had 1-septate, slightly constricted, brown, finely verruculose ascospores, 27.5–35 × 14–17 µm.

On the host tissue, however, it formed synnemata, which were absent in culture. Videira et al. (2017) commented that Paramycosphaerella was heterogeneous, and although most species were known by their sexual morphs, some had zasmidium- or pseudocercospora-like asexual morphs. Phylogenetically and morphologically, P. syzygii is distinct from other species described in the genus.

Notes — Brayford & Chapman (1987) reported a wilting disease of Laurus nobilis on the Isles of Scilly, and later on Arbutus andrachnoides and Gaultheria shallon in West Devon, UK. Lechat et al. (2010) linked this disease to a new species, Calonectria lauri (validated by Liu et al. 2020), which was re- ported from leaves of Ilex aquifolium in France and the Nether- lands, and roots of Buxus sempervirens in Belgium. Calonectria lauri is sister to C. californiensis described in the present study. Although the two species can be distinguished in that C. lauri has conidia that are somewhat larger, (45–)55–68(–73) × (4–)5–6(–7) μm, they are best separated based on their DNA phylogeny. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of CPC 29619 had highest similarity to Calonectria lauri (strain CMW 23682 (R), GenBank MT359736.1; Identities = 534/534 (100 %), no gaps), Calonectria citri (strain CMW 23675 (R), GenBank MT359683.1; Identities = 533/534 (99 %), no gaps) and Calonectria tunisiana (now synonym of Calonectria pseu- domexicana; strain CAL-EU2, GenBank MT345681.1; Identities = 531/534 (99 %), no gaps).

Freitas, Hyang B. Lee, T.T.T. Nguyen, M.O. Cruz & A.L. Santiago, sp. nov. Etymology. Refers to the Reserve Parque Nacional e Histórico do Monte Pascoal from where the species was isolated. Classification — Cunninghamellaceae, Mucorales, Mucoro- mycetes. Mycelium with hyaline to pale brown rhizoids, slightly branched, commonly finger-like or lobular, 25–240 × 2.5–7 µm. Stolons hyaline to pale brown, irregularly septate, with septa commonly observed near the origin of sporangiophores, smooth-walled, 5–10 µm diam. Sporangiophores pale brown, arising along the pale brown stolons or terminal, single or in whorls of 4–6(–7), simple or branched, with branches shorter or longer than the main sporangiophore, with slightly incrusted wall, (45–)120– 325(–400) × 4–8 μm; some branches may re-branch up to five times with a septum below the sporangium. Sporangia pale brown, pyriform, smooth-walled, 25–40 × 21.5–35 µm, with a funnel-shaped (short or long) apophysis, 5–15 × 11–21.5 µm. Columellae hyaline to brownish grey, mostly subglobose, some hemispherical, and fig-shaped, smooth-walled, fre- quently with one projection, less commonly with two or rarely three projections on its surface, 9.5–25 × 10–30 µm diam, or without projections on the largest columellae; collar distinct or absent. Projections cylindrical, conical, some bulbous at distal end, and some may show a constriction on its apical portion, 2.5–5.5 × 1.5–5 µm. These projections may arise separated at the base or fork. Sporangiospores hyaline, short cylindrical, slightly constricted in the centre, smooth-walled, 3–5 × 1.5–3 µm. Chlamydospores present in aerial hyphae, globose, 5–10 µm diam, subglobose and ovoid, 7–15 × 6–15 µm. Zygospores not observed.

Notes — The ITS and LSU phylogenetic trees showed that A. montepascoalis is a new species related to A. bonitoensis, but also close to A. anomala, A. multispora and A. jindoensis. The morphological characteristics differ among these spe- cies. Absidia montepascoalis presents rare swellings (on MEA at 25, 30 and 35 °C), and abortive sporangia are never formed. However, sporangiospores of A. montepascoalis are exclu- sively cylindrical. In contrast, A. bonitoensis produces sporan- giophores commonly with one or more randomly distributed swellings, as well as some sporangiophores with abortive sporangia that bear a new sporangiophore. In addition, A. bo- nitoensis produces globose to subglobose and rarely cylindri- cal sporangiospores (Lima et al. 2020). Absidia multispora produces sporangiophores arranged singly or in whorls of two to four, with the formation of occasional abortive sporangia, and sporangiospores are of varied shapes such as globose, subglobose, ellipsoid, short cylindrical, ellipsoidal and irregular (Cordeiro et al. 2020), whereas A. montepascoalis produces sporangiophores in whorls of up to seven, and does not form abortive sporangia. Sporangiospores are typically cylindrical and slightly constricted at the centre. Absidia anomala can be differentiated from A. montepascoalis as the former produces sporangiophores singly and in whorls of two, and only one projection can be observed at the columellae. The colony is purple to violet and azygospores are produced (Hesseltine & Ellis 1964). Absidia jindoensis is morphologically different from A. montepascoalis as it has 2–6(–8) sporangiophores in a whorl, hemispherical columellae, sometimes subglobose, com- monly with one projection on its surface, and sporangiophores cylindrical with rounded ends (Wanasinghe et al. 2018).

Ostrý & Hubka, sp. nov. Etymology. Name reflects its boat-shaped ascospores. Classification — Chaetomiaceae, Sordariales, Sordariomy- cetes. Micromorphology (on oatmeal agar; OA): Ascomata superficial, ostiolate, subglobose or ovate, c. 130–200 μm diam, with brown walls of textura angularis. Ascomatal hairs pale green or greenish olivaceous in reflected light. Terminal hairs septate, warty, undulated at apices, brown to grey, 5–6.5 μm diam near the base, 2–2.8 μm diam at the tip. Lateral hairs straight or inequilaterally undulated. Asci clavate, 8-spored, about 30–37 × 9–12 μm. Ascospores dark brown, broadly navicular in side view, 7.2–8.8 × 4.5–5.5 μm (mean ± standard deviation: 8.0 ± 0.4 × 4.9 ± 0.3), lemon-shaped seen from above, 7.2–8.8 × 5.5–6.1 μm (8.0 ± 0.4 × 5.7 ± 0.2), with two apical germ pores. Asexual morph unknown. On PCA at 37 °C after 7 d, amor- phous crystals in pigmented zone of agar were observed, about 5–7 μm diam. Culture characteristics — (at 25 °C after 7 d, in darkness): Colonies on potato carrot agar (PCA) 32–37 mm diam, oliva- ceous in the centre due to formation of ascomata, finely filamentous and pale towards the edges, with pale vinaceous exudates diffusing into the medium around the colonies; reverse dark grey-vinaceous in the centre, pink-grey towards the edges; ascomata maturing after 14 d. Colonies on OA 39–41 mm diam; the appearance of colonies similar to those on PCA, but the pigmentation is more pronounced, and the colonies form more abundant aerial mycelium; ascomata maturing later than on PCA. Colonies on malt extract agar (MEA) 35–38 mm diam, with pinkish white aerial mycelium, wine red exudates diffus- ing into the medium, reverse dark ruby; ascomata not formed after 7 d. Colonies on PCA at 37 °C after 7 d 18–20 mm diam. Typus. cZech republic, Brno, tea bag with fruit tea (lemons, rose hips and apple pulp), Nov. 2001, V.

Notes — Arcopilus navicularis shares an identical ITS and LSU region with A. aureus, A. amazonicus and A. globulus. BLAST analysis with the rpb2 sequences showed 96–96.5 % similarity with the latter three mentioned species, while the tub2 gene showed only 87–87.5 % similarity. The strain CCF 3252 was originally identified as Chaetomium aureum (Kubátová 2006), currently Arcopilus aureus. The latter has similar pigmentation of ascomatal hairs, but differs in ascospore shape. Arcopilus cupreus, A. amazonicus and A. globulus have similar shaped ascospores to A. navicularis, but their ascospores are slightly larger. Arcopilus cupreus dif- fers moreover by red or orange-red hairs in reflected light, and A. amazonicus has smaller ascomata and yellow mature hairs (Ames 1949, Von Arx et al. 1986, Wang et al. 2016, Raza et al. 2019, Sousa et al. 2020).

Malysheva & L.B. Kalinina, sp. nov. Etymology. The name refers to the geographic region – Siberia, where the species was discovered. Classification — Bolbitiaceae, Agaricales, Agaricomycetes. Basidiocarps small to medium-sized. Pileus 8–23 mm diam, at first hemispherical or convex, becoming plano-convex without distinct umbo, with incurved, often undulating striate margin; hygrophanous; surface glabrous, viscid, wrinkled at centre, smoked oak brown (080 30 26) or beech brown (070 30 20), olive black (080 30 10) at centre and bamboo yellow (080 60 40) at margin (all colour codes of macroscopic features are given following the RAL DESIGN colour range system). Lamellae narrowly adnate, crowded, with lamellulae, slightly ventricose, natural rice beige (080 80 20) to ash yellow (075 80 40) or orient yellow (075 80 50), edge even or somewhat serrulate, con- colorous or slightly paler. Stipe 25–40 × 2–4 mm, cylindrical, fragile, hollow, whitish to lemon ice cream yellow (095 90 30), entirely pruinose. Context thin, whitish. Smell and taste not dis- tinctive. Basidiospores 7.3–9.5 × 4.0–5.0 μm, Q = 1.60–2.00, Qav = 1.80, n = 40, broadly ellipsoid or slightly flattened and amygdaliform in side view, yellow-brown in KOH, slightly thick- walled, with prominent central germ-pore; distinctly punctate under the compound microscope and verrucose under scanning electron microscope (SEM) – entirely covered with numerous isolated papillae. Basidia predominantly 4-spored, sporadically 1–2-spored, 20–27 × 8–10 μm, broadly clavate, surrounded by similar-shaped scarce pseudoparaphyses. Cheilocystidia numerous, 24.5–41.5 × 5.2–8.0 μm, subcylindrical or cylindrical with obtuse to subcapitate apex, hyaline or slightly brownish, thin-walled. Pleurocystidia absent. Pileipellis hymeniform, com- posed of 15–50 × 10–20 μm, broadly clavate or subglobose and globose elements, in chains, thick-walled, almost hyaline or greyish brown. Pileocystidia rather numerous, represented by cylindrical, often with subcapitate or capitate apex, or nar- rowly clavate elements, 30–55 × 5–10 μm, weakly to strongly pigmented with intracellular greyish brown and granular pig- ment, thick-walled. Stipitipellis a cutis, containing fascicles of caulocystidia, 37–63(–83) × 5.5–11.0 μm, subcylindrical, cylindrical or narrowly clavate, sometimes irregular-shaped and septate, hyaline, slightly thick-walled. Clamp-connections present and numerous in all parts of basidiocarp. Habitat & Distribution — Growing in small groups on а moss covered rotting trunk of aspen (Populus tremula).

Typus. ruSSia, vicinity of Novosibirsk, ‘Academic Town’, mixed aspen-birch forest, ravine slope, N54°48'49.1603" E83°08'35.2283", on fallen trunk of Populus tremula, 7 July 2019, T. Bulyonkova (holotype LE 313563, ITS and LSU sequences GenBank MW682333 and MW682334, MycoBank MB 839016). Notes — Bolbitius sibiricus is characterised by its glutinous- viscid and dark olive-brown pileus, pale stipe, subcylindrical or cylindrical cheilo- and caulocystidia, numerous pileocystidia, ornamented basidiospores, and lignicolous habitat. Morpholo- gically it resembles B. viscosus originally described from North America (Watling 1975), but in addition to genetic differences (a dissimilarity of nrITS sequences of up to 19 %) it differs from the latter by having slightly larger basidiocarps, more cylindrical cheilocystidia, not clavate and longer caulocystidia (vs 14–33 μm in B. viscosus), and the presence of numerous pileocystidia. Another Bolbitius species with basidiospores ornamented under SEM, the North American B. callistus, can easily be distinguished from the new species by its conspicu- ously coloured basidiocarps with green, yellow and reddish tints, fusiform cheilocystidia, differently shaped pileocystidia and the absence of clamp-connections (Watling 1987).

Habitat & Distribution — Currently known only from the type locality, in association with Quercus baloot (Fagaceae). Typus. pakiStaN, Khyber Pakhtunkhwa Province, Kurram District, Parachi- nar, 22 Aug. 2019, A. Naseer AS-PC43 (holotype LAH 36760, partial LSU and ITS sequences GenBank MT825244 and MT825245, MycoBank MB 839366). Notes — Butyriboletus parachinarensis is distinguished based on morphology and the distinctness of partial ITS and LSU sequences. Butyriboletus sanicibus from China is similar based on BLAST comparison of our partial ITS sequence (97.04 % identity) but is known to have a larger pileus with an incurved margin and a pore surface that is slightly greenish with age (Arora & Frank 2014). Furthermore, B. sanicibus has subfusoid basidiospores with an average Q value of 2.8 while B. parachinarensis has fusoid basidiospores with an average Q value of 2.4. Butyriboletus yicibus from China is similar based on BLAST comparison of our partial LSU sequence (97.24 % identity) but can be distinguished from B. parachinarensis by its more gracile stature and tendency to stain blue-grey rather than blue when bruised (Arora & Frank 2014). Butyriboletus yicibus can have a longer stipe (up to 15 cm) than B. parachinarensis. Colour illustrations. Stands of Quercus baloot around Parachinar.

Named after ‘amba’ meaning Mango tree in Marathi language, the host of the fungus. Classification — Castanediellaceae, Xylariales, Sordario- mycetes. On decaying leaves of Mangifera indica: Mycelium pale to dark brown, immersed, septate, hyphae 2–3.5 µm diam. Conidio- mata sporodochial, scattered, erumpent, starting as a penicillate tuft of conidiophores with central attachment point, expanding lateral and apical, becoming densely branched, but with central attachment, stipitate, 20–80 µm diam, 35–120 µm high. Setae rare, hyaline, flexuous or undulate with obtuse tips, attached to the base of the sporodochia, up to 87 µm long and 2–2.5 µm wide. Conidiophores subcylindrical, densely branched, multi- septate, medium to dark brown, smooth. Conidiogenous cells terminal and intercalary, ampulliform, pale brown, smooth, apex truncate, polyblastic, phialidic?, 7–10.5 × 2–2.8 µm. Conidia solitary, hyaline, smooth, falcate with subobtuse or acute ends, 0–2-guttulate, (8–)9.5–15.5(–19) × 1.5–1.8(–2) µm. Culture characteristics — (on malt extract agar at 25 ± 2 °C after 1 mo): Colonies floccose or umbonate at centre, grey (5E1) to brownish orange (5C4) (Kornerup & Wanscher 1978), velutinous or immersed, dark brownish grey (5F2) to dark grey (5F1); reverse dark brownish grey (5F2) to dark grey (5F1), colonies reaching 40–50 mm diam. Typus. iNdia, Tamhini Ghats, Tamhini village, on leaves of Mangifera indica (Anacardiaceae), 23 July 2018, K.C. Rajeshkumar (holotype AMH 10211, cultures ex-type NFCCI Raj18 = NFCCI 4774, ITS and LSU sequences Gen Bank MN660236 and MN660235, MycoBank MB 833316). Notes — Morphologically, C. ambae resembles C. acaciae (Crous et al. 2015a), having sporodochial conidiomata compared to all other species of Castanediella. However, the sporodochia in C. ambae are smaller in width and slightly longer than those of the type species C. acaciae. The presence of hyaline, flexuous setae with obtuse tips arising from the base of the sporodochia, is another unique feature of C. ambae. Furthermore, conidia are marginally longer in C. ambae in comparison to those of C. aca- ciae. Phylogenetic analyses based on combined ITS and LSU sequence data resulted in a unique clade for the sporodochial Castanediella species, C. acaciae and C. ambae from other taxa in Castanediella. The new species form a fully supported (100 % bootstrap support, posterior pro bability = 1.00) clade with C. acaciae. Based on a megablast (type BLASTn) search of NCBIs GenBank nucleotide database, the closest hits us- ing the LSU sequence are C. acaciae (GenBank KR476763; Identities = 844/848 (99 %), no gaps), C. cagnizarii (GenBank MH874222; Identities = 837/848 (99 %), no gaps) and C. euca- lypti (GenBank KR476758; Identities = 837/851 (98 %), three gaps (0 %)). Closest hits using the ITS sequence had highest similarity to C. acaciae (GenBank NR_137985; Identities = 506/526 (96 %), five gaps (0 %)), C. tereticornis (GenBank NR_161116; Identities = 487/532 (92 %), eight gaps (1 %)) and C. cagnizarii (Gen Bank MH862597; Identities = 481/530 (91 %), ten gaps (1 %)). Phylogram generated from a maximum likelihood (ML) analysis based on LSU and ITS sequence data representing the genus Castanediella in RAxML v. 8.2.12 (Stamatakis 2014). Related sequences are taken from Lin et al. (2019). Eighteen strains are included in the combined analyses which comprise 1 363 characters and 530 characters for LSU and ITS, respectively, after alignment. Subsessila turbinata (KX762288, KX762289) was used as the outgroup taxon. Single-gene analyses were also per- formed to compare the topology and clade stability with combined gene analyses. Tree topology of the maximum likelihood analysis is similar to the Bayesian analysis performed in siMBa (Mishra & Thines 2014). The best scoring RAxML tree with a final likelihood value of -3866.720205 is presented. The matrix had 256 distinct alignment patterns, with 7.71 % undetermined characters or gaps. Estimated base frequencies were as follows: A = 0.253765, C = 0.209910, G = 0.261361, T = 0.274964; substi- tution rates AC = 1.675661, AG = 3.141033, AT = 2.412224, CG = 0.281419, CT = 6.326033, GT = 1.000000; gamma distribution shape parameter α = 1.214174. Bootstrap values for maximum likelihood (MLBS) equal to or greater than 50 % and Bayesian posterior probability clade credibility values greater than 0.95 (BPP; the rounding of values to 2 decimal proportions) from Bayesian-inference analysis (siMBa) labelled on the nodes (MLBS/BPP).

Conidia in mass orange to apricot. Typus. coSta rica, from an unidentified fern (Pteridophyta), unknown collection date and collector (deposited in CBS collection Feb. 1999 by P. Lafeber), (holotype CBS H-20817, culture ex-type CBS 101611, LSU sequence GenBank MW724319, other sequences from Damm et al. 2012a, MycoBank MB 839338). Notes — Based on blastn searches on NCBI GenBank, the ITS sequence of strain CBS 101611 is identical with that of C. scovillei, including its ex-type strain and with strain CBS 129820 from Passiflora in Colombia (Damm et al. 2012a), but also with strains from fronds of Rumohra adiantiformis (leather leaf fern) with anthracnose from Costa Rica (Schiller et al. 2006) and Florida, USA (MacKenzie et al. 2009). Phylo- genies inferred from concatenated ITS, chs-1, tub2, act, his3 and gapdh sequences placed the fungus in clade 1 of the C. acutatum species complex (Damm et al. 2012a, this study), where it forms a distinct single-strain lineage. The species can be distinguished with act, gapdh, his3 and tub2 sequences, best with act and tub2. The closest matches with the act and tub2 sequences were with 99 % identity (two nucleotides difference) several Colletotrichum strains including the ex-type strains of C. limetticola, C. lupini and C. paranaense (Nirenberg et al. 2002, Bragança et al. 2016, Damm et al. 2012a), and Colletotrichum sp. CBS 129810 from tamarillo in Colombia, respectively, while the ex-type strain closest to the tub2 sequence was three nucleotides different to that of C. tam- arilloi (Damm et al. 2012a). The closest matches to the gapdh and his3 sequences were with 99 % identity (one nucleotide difference) strains of C. abscissum, including its ex-type (Crous et al. 2015a), and strains CBS 129820 and CBS 129821 from Passiflora in Colombia as well as C. costaricense strain CBS 211.78 (Damm et al. 2012a), respectively. The gapdh sequence of C. filicis differs from those of the strains from leatherleaf fern in Florida (MacKenzie et al. 2009) in two or four nucleotides, respectively; they are therefore unlikely to be conspecific.

Istel, J. Pawłowska & Wrzosek, sp. nov. Etymology. The specific epithet ‘antarctica’ refers to the isolation locality – Antarctica. Classification — Pleosporaceae, Pleosporales, Dothideo- mycetes. Colonies: On potato glucose agar (PGA) after 7 d of growth at 24 °C reaching 2.58 cm (± 0.34 cm) diam. Initially sterile, pink in the centre, becoming orange at the colony edge. Reverse orange to dark brown. Aerial hyphae and ascocarps appear after 6 wk of incubation at 4 °C. Ascocarps perithecial, separate or in groups, dark brown to almost black, strongly enclosed in aerial hyphae, ovoid to spherical, 339 (± 103) × 299 (± 97) µm, without distinct ostiole, 51–116 µm diam; neck very short, up to 26 µm long; operculum semispherical, flattened, 102–197 × 97–182 × 24 µm; perithecial hyphae dark; wall of 2–3 cell layers. Asci bitunicate, mostly 8-spored, 72–84 × 18–26 µm, immature asci shorter (~ 60 µm), cylindrical to clavate, bitu- nicate with a rounded apex. Ascospores lanceolate to ovoid, clavate, yellow to pale brown, elongated, asymmetrical with a blunt apex, muriformly, with 6–8 transvers septa, consisting of 10–17 cells, apical cell not divided, 31 (± 2) × 13.5 (± 1) µm. Typus. aNtarctica, King George Island, 50 m from the front of Sphinx Glacier, coordinates S62°11'36.3" W58°27'18", isolated from soil sample using Warcup method on Minimal Media with 0.01 % diesel oil, 21 Mar. 2018, Ł. Istel (holotype WA0000074564 – dried specimen, culture ex-type CBS 147272, ITS and LSU sequences GenBank MW040594 and MW040597, MycoBank MB 837527). Notes — The genus Comoclathris was described by Cle- ments (1909). In 2015 the genus was placed in the Pleosporales by Ariyawansa et al. (2015). Currently, the genus consists of 41 registered names in MycoBank. However, data on only 10 species are represented in GenBank. The type species of the genus is C. lanata, which lacks ITS nrDNA sequence data. Ariyawansa et al. (2014) used sequences of two strains of C. compressa (CBS 157.53 and CBS 156.57) as reference. Those two strains together create a well-supported clade inside Pleosporaceae but outside the Alternaria complex. The mor- phological characteristic features of the genus are the presence of operculate perithecia, and asymmetrical, muriform, strongly divided ascospores (Shoemaker & Babcock 1992, Wanasinghe et al. 2018) and the isolate described here represents these features. The main characteristic that differentiates C. antarctica from another species in the genus is the 6–8 transversal asco- spore septa. Additionally, Comoclathris representatives were never observed before in Antarctica. The rDNA sequences of ITS and LSU regions of C. antarctica are showing the highest similarity (95 % and 97 % respectively) to C. spartii (GenBank KM557160.1). However, C. spartii is saprobic on Spartium junceum and has smaller ascocarps (Crous et al. 2014b). The main morphological difference between C. antarctica and C. com- pressa is in the number of ascospore septa. Comoclathris ant- arctica has 6–8 transverse septa while ascospores of C. com- pressa only have three septa (Shoemaker & Babcock 1992). Comoclathris antarctica is the most similar to C. arctica based on morphology. However, C. arctica has much smaller asco- carps (~ 200 µm diam) and larger asci, being up to 120 µm long (Shoemaker & Babcock 1992).

Typus. auStralia, Queensland, Baxter’s Hill, Gowrie Junction, remnant dry rainforest, S27°29'7" E151°52'41", altitude 570 m, isolated as an endo- phyte from healthy leaves of Geijera salicifolia (Rutaceae), 20 Aug. 2019, A.B. Sharma (holotype BRIP 71282a, ITS and LSU sequences GenBank MT573531 and MT525302, MycoBank MB 836228). Notes — Members of Coniochaeta are characterised by dark- brown to black, globose or subglobose perithecia, longitudinal germ slits in dark ascospores and a phialidic asexual morph (Nasr et al. 2018, Harrington et al. 2019). Coniochaeta spp. occur as endophytes and human and plant pathogens (Damm et al. 2010, Khan et al. 2013, Xie et al. 2015). A number of bioactive compounds have been isolated from members of the genus including coniochaetone and coniosetin (Wang et al. 1995, Segeth et al. 2003). Coniochaeta salicifolia is distinct on BLAST searches from C. africana (ITS GenBank MH863095, 94 % over 542 bp) and C. navarrae (ITS GenBank NR_154808, 93 % similarity over 375 bp). Coniochaeta salicifolia differs morphologically from C. africana by its white and long setae (up to 545 µm). The LSU sequence of C. salicifolia has 98 % similarity to C. rosae (over 819 bp; GenBank NG_066204). Maximum Likelihood tree obtained by analysis of nrDNA ITS sequences from C. salicifolia (bold) and related Coniochaetales species in GenBank. Phylogenetic analysis was conducted in MEGA v. 10 (Kumar et al. 2018a) using ClustalW for alignment (652 bp in the final dataset) and Kimura 2 parameters, Gamma distribution and 1 000 bootstrap re-samplings to build the tree. Bootstrap values less than 70 % are not shown. Coniolariella gamsii (Xylariaceae) was used as an outgroup to root the tree. 430 Persoonia – Volume 46, 2021 Cortinarius bonachei 431Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Juan de Dios Reyes García, Paseo Virgen de Linarejos 6 2ºD, 23700 Linares (Jaén), Spain; e-mail: juandedioscortinarius@gmail.com Colour illustrations.

Bonache, a dear friend, and after a lagoon of the same name, where this species was collected. Classification — Cortinariaceae, Cortinariales, Agaricomy- cetes. Pileus 25–45(–50) mm diam, brown dark (Séguy 1936; 696, 701) becoming brown (694, 695), at first conical campanulate, later convex with a persistent obtuse and low umbo. Margin first incurved, straight, later extended. Surface dry, hygrophanous, matt and finely innate-fibrillose, sometimes with white veil remnants. Lamellae 4–5 mm diam, medium spaced, adnate to sinuate, brown when young (694, 695), paler at the edge (705), with lamellulae. Stipe 35–50 × 4–6 mm, cylindrical, subbulbous towards the base (8 mm diam). Surface fibrillose, with whitish fibrils on a pink background. Context reddish brown on the pileus, and lighter reddish brown towards the base of the stipe. Odour and taste indistinct.

Reyes (holotype JA-9576, iso- type JDRG16110607, ITS sequence GenBank MW752900, MycoBank MB 839008). Notes — Different public nucleotide databases were consul- ted using the blastn algorithm: GenBank, UNITE and BOLD, comparing the generated holotype sequence with the closest species of Cortinarius subg. Telamonia, differing with C. roseo- castaneus (GenBank NR131866) in seven nucleotides and eight indels. Cortinarius roseobasilis (GenBank NR153059) in eight nucleotides and 11 indels and C. fulvopaludosus (GenBank NR154868)) in six nucleotides and 17 indels, 95.59–96.95 % similarity. Morphological characters distinguish C. bonachei from related species: C. roseocastaneus has a very dark brown to black- ish brown pileus, dark brown lamellae, and less verrucose basidio spores. Ecological characters distinguish C. bonachei from C. fulvopaludosus, a species associate with conifers (Abies, Picea and Pinus spp.) and deciduous hosts such as Betula, Alnus and Salix spp., in forests of Northern Europe. Cortinarius roseobasalis, an American species, is linked to Quercus garryana. 432 Persoonia – Volume 46, 2021 Cortinarius brunneovolvatus 433Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1235 – 13 July 2021 Cortinarius brunneovolvatus A. Mateos & J.D. Reyes, sp. nov. Etymology. The first part of the epithet (‘brunneo’) refers to the general brown colour of the basidiomata, the second part (‘volvatus’) refers to the fact that it is provided with a veil covering the stipe in the form of a volva. Classification — Cortinariaceae, Agaricales, Agaricomyce- tes. Basidiomata of medium size, growing gregarious to fasciculate, with a sordid appearance ven when young. Pileus 50–70(–90) mm diam, convex to plano-convex when young, flat to de- pressed in developed specimens, with a broad obtuse umbo and wavy margin, incurved at first but later straight, sometimes somewhat incised; cuticle reddish brown (Séguy 1936: 146), dark (126) to sordid (177), a bit hygrophanous, with a large amount of white veil in the centre and fibrillose remnants towards the margin, which is somewhat exceeding. Lamellae spaced, widely spaced at maturity, emarginate, with abundant short and long lamellulae, up to 10 mm thick, with a wavy and sometimes somewhat serrate edge; beige when young (190) but soon reddish brown (187, 191). Stipe 50–70(–120) × 10–15 mm, cylindrical to claviform, with a bulbous base up to 25 mm thick, recurved, with a fibrillose surface presenting white velar remnants in the lower half, more abundant at the base and finally disappearing elsewhere, with silver fibrils at the apex; reddish brown, paler towards the top (202, 187). Context firm, reddish brown in the centre of the pileus (161), paler towards the top of the stipe (162), greyish brown towards the base (200), odour slightly earthy, taste not remarkable. Exsiccatae: pileus sordid brown to dark greyish brown, especially in the centre; stipe brownish grey. Macrochemical reactions: KOH, on cuticle dark brown, on flesh somewhat brownish at the pileus and subnull elsewhere; Guaiac, ++ rather fast. Basidiospores ellipsoid to subamygdaliform, with ornaments consisting of evenly distributed isolated warts of medium height and thick- ness, (8–)8.9–9.5–10.3(–11.3) × (4.9–)5.5–6.1–6.7(–7.5) µm; Q = (1.4–)1.5–1.6–1.7(–1.8); n = 80; Vm = 189 µm3, sometimes with large central oil droplets. Lamellar edge fertile or without true cystidia, with scattered basidioliform banal cells. Hymenophoral trama consisting of 3–10 µm wide cylindrical hyphae, with greyish parietal pigment and sometimes with vacuolar pigmentation. Basidia claviform, tetrasporic, 25–35 × 8–10 µm, with stigmata 2–4 µm long. Pileipellis consisting of a duplex cutis (Type 1 according to Bidaud et al. 2004). Epicutis formed by a thin layer of radial hyphae of (3–)4–8(–14) µm, with few free and hardly differentiated tips, and greyish brown parietal incrusted pigment. Subcutis well differentiated from the epicutis, consisting of a layer of subcellular elements of 17–23 µm diam, with brownish parietal pigmentation. Clamp connections present in all tissues. Habitat & Distribution — Gregarius and caespitose, in large groups among leaf litter of Quercus ilex subsp. ballota, on rich calcareous soils, in Mediterranean sclerophyllous mountain forest in Sierra Mágina, Subbetic System (southern Iberian Peninsula), consisting of Q. ilex subsp. ballota, Q. coccifera and Pinus spp. The existence of an ITS sequence in GenBank (HQ204636.1) of ectomycorrhizal communities in a Mediter- ranean forest ecosystem dominated by Quercus ilex which is almost identical to that obtained in the present study indicates the presence of C. brunneovolvatus in the Q. ilex forests of France.

Phylogeny — The final alignment included 663 bp of which 153 were variable and 108 were parsimoniously informative among 31 sequences (three newly generated, 28 retrieved from public databases). For the elimination of ambiguously aligned sites, this alignment was optimised in GBlocks (Cas- tresana 2000) with the least restrictive parameters resulting in 501 positions, of which 376 were conserved, 125 variable, 89 parsimoniously informative and 36 singletons. JModeltest v. 2.1.4 (Darriba et al. 2012) was used to select the best nucle- otide substitution model, using the Akaike Information Criterion (AIC, Akaike 1974) analysis. The GTR+I+G model was selected. Maximum likelihood (ML) and Bayesian inference (BI) analyses were performed using Geneious v. 6.1.7. Supporting statistical nodes in the ML analyses were inferred from 1 000 bootstrap replicates. Phylogenetic trees were drawn with FigTree v. 1.4, and finally adapted in Adobe Illustrator CS5. Notes — Cortinarius brunneovolvatus has as characteristic morphological characters, chestnut-brown colour of its basidio- mata, the large amount of white veil remnants on the pileus and thickly covering bulbous base of stipe, and its ellipsoid to subamygdaliform spores with medium-sized ornaments. However, these features are present also in several species of Telamonia s.lat. and, more specifically, in the sections Brunnei, Sordescens and Lanigeri (Brandrud et al. 1989, 1992, 1994, 1998, Melot 1990, Bidaud et al. 2002, 2009), as well as other species in section Bovini where C. brunneovolvatus is nested, based on phylogenetic analyses, as well as morphological evi- dence representing the type species C. bovini ((Brandrud et al. 2012: pl. E20, Niskanen et al. 2013). Section Bovini (Moser & Horak 1975), underwent several modifications by its original author (Moser 1978, 1983, 2001, Moser et al. 1995), who included several European and South American species, one North American species (C. pseudobovinus) and others from the Southern Hemisphere. Subsequently, Bidaud et al. (2009) added some new species and suggested several other modifications.

The latter feature, although it was partially visible in some pileipellis photos of Crepidotus volubilis (Kumar et al. 2018a), was generally not reported for the genus Crepidotus as a whole (whose representatives were characterised either by the complete absence of clamp connections, or by their pres- ence in all tissues), but it was reported quite regularly, e.g., for entolomataceous fungi (e.g., Jančovičova & Adamčik 2012). As shown in the molecular phylogram, C. wasseri represents a distinct and rather distant clade from neighbouring species clades, forming a basal lineage to the C. palodensis-C. subver- rucisporus complex. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS se- quences were Uncultured Basidiomycota 4S1_A12 (GenBank EU489965.1; Identities = 819/881 (93 %), 18 gaps (2 %)) and Uncultured fungus FDBC50 (GenBank JQ247381.1; Identities = 818/884 (93 %), 18 gaps (2 %)). The closest hits using the LSU sequence C. aff. alabamensis (GenBank GQ892982.1; Identities = 1 347/1 368 (98 %), no gaps) and C. mollis (Gen- Bank DQ986293; Identities = 1 346/1 368 (98 %), no gaps). Other morphologically similar species with minute basidiomes (see Supplementary material FP1236-1) bear only superficial similarities with C. wasseri in various aspects, e.g., lageniform cheilocystidia (C. epibryus, C. lagenicystis), or smooth basidio- spores (C. autochtonus, C. epibryus).

Refers to its morphological similarity of Cuphophyllus flavipes. Classification — Hygrophoraceae, Agaricales, Agaricomy- cetes. Basidiomata clitocybioid. Pileus 15–40(–50) mm diam, as young conical to plano-convex with a broad and blunt umbo and in- curved margin, later becoming more plane, with age sometimes becoming slightly depressed and with somewhat undulating and lobed margin. Lubricous to subviscid, sometimes translucently striate at margin up to 2/3 towards the centre, hygrophanous, as young grey violet or ash grey to greyish brown to brown, with a violaceous tint, dark at centre, paler towards the margin and with age discolouring to pale grey to grey violet. Lamel- lae short to deeply decurrent, arcuate, distant to subdistant, lamellae that reach the stipe = 30–40(–50), interspaced with lamellulae, a few furcate, intervening, first whitish to greyish, when greyish with paler margin, with age pale greyish. Stipe 30–65 × 3–7 mm, cylindrical and usually thickest at the apex or upper half, tapering and often bending towards the base, dry, matt, fibrillose lengthwise, pale, whitish grey, at the base normally pale yellow, up to 1/3 of the stipe. Context concolorous. Smell weak, indistinct, taste mild. Micro-morphological characters measured from dried material dehydrated in 3 % KOH and ammoniacal Congo red solu- tion. Spores (5.5–)7.0–7.3(–8.8) × (4.2–)5.2–5.4(–6.1) µm, n = 117, av. 7.2 × 5.3 µm, Q = 1.34–1.39, subglobose to ellip- soid, often lacrimoid, with a distinct and often oblique apicu- lus, hyaline, white in deposit, non-amyloid. Basidia 35–54 × 7.5–9 µm, 2–4-spored observed, sterigmata 5–6.5 µm. Lamellar trama irregular interwoven, made up of cylindrical hyphae, 5.5–7 µm wide and 30–60 µm long, some branched and inflated. Pileipellis an ixocutis, 50–110 µm thick with radially interwoven hyphae, 3–6 µm wide, 30–60 µm long, incrusted with finely granular pigments. Hyphae in subpellis interwoven, 7–10 µm wide, 40–55 µm long, with inflated end cells up to 20 µm wide. Clamp connections frequent in all tissues. Ecology & Distribution — Associated with nutrient poor semi-natural grasslands, among mosses, herbs and grasses, with the soil ranging from rather acid to (rarely) moderately calcareous. Confirmed distribution so far from Norway, Sweden and Denmark. Typus. Norway, Vestland, Alver, Lygra (Utluro), 25 m a.s.l., in semi- natural grassland pasture, 3 Sept. 2019, J.B. Jordal, JBJ19-013 (holotype OF-258322, isotype GB-0207610, ITS-LSU sequence GenBank MW714630, MycoBank MB 839261). Notes — Cuphophyllus flavipesoides belongs in a complex of closely related and morphologically similar species. In macro- and micromorphology it is very similar to C. flavipes. On average we find that the spores in C. flavipes are more subglobose with the average measurements 7.1 × 5.6 µm, and Q = 1.22–1.27, compared to the average in C. flavipesoides, 7.2 × 5.3 µm, Q = 1.34–1.39. In Voitk et al. (2020) an average value for the spores of the selected epitype of C. flavipes was measured to Q = 1.2. The two species differ in ITS1 sequence data by four substitutions and four single bp insertion/deletion events, in the ITS2 by six substitutions and three single bp insertion/de- letion events. The sequences in the C. flavipesoides clade are homogenous, suggesting an independent evolutionary lineage. Based on the sequence data available, the two species differ somewhat in geographic distribution where C. flavipes seems to be more common in southern Europe and confirmed from Italy, Austria, Germany, UK, Denmark, SW Norway and S Sweden, whereas C. flavipesoides has a more northern distribution range and is confirmed from Norway, Sweden and Denmark and is most common in the northern/boreal areas. However, the two species overlap and co-occur in some areas in southern parts of Scandinavia. Cuphophyllus pseudopallidus is also closely related and re- sembles C. flavipesoides, but it differs in morphology by having a pale beige brown (ecru-drab) to pale greyish pileus colour and ivory yellow lamellae, a stipe that is glabrous, striate and white-shining, and somewhat smaller spores (Hesler & Smith 1963, Voitk et al. 2020). So far only known from North America and Japan.

Kunjithapatham Dhileepan in sedgeland, eastern Tanzania. Inflo rescence of Cyperus aromaticus colonised by Curvularia tanzanica; conidio phores; conidia. Scale bars = 1 mm (inflorescence), 10 µm (others). Notes — Curvularia tanzanica is only known from collections on Cyperus aromaticus (syn: Kyllinga polyphylla) (Cyperaceae) in Tanzania. Curvularia tanzanica was discovered while search- ing for plant pathogens on C. aromaticus in its native range in equatorial Africa. The aim of the surveys was to find plant pathogens that may have potential for the biological control of C. aromaticus in northern Queensland, Australia, where the sedge has become an invasive weed in pastures and sugar cane crops. Curvularia tanzanica colonised the floral parts of C. aromaticus that superficially resembled the darkened crus- tose inflorescences of Sporobolus spp. (Poaceae) covered (and sometimes destroyed) by certain species of Curvularia spp. (Luttrell 1976, Alcorn 1982, Tan et al. 2018). The multilocus phylogenetic analysis of the ITS and gapdh loci placed C. tanzanica sister to C. gladioli strain CBS 210.79. Based on a blastn search, C. tanzanica differs from C. gladioli in ITS (GenBank LT631345; Identities 558/565 (99 %), no gaps) and gapdh (GenBank LT715802; Identities 531/540 (98 %), no gaps). Morphologically, C. tanzanica has straight conidia, which differentiates it from C. gladioli (illustrated in Parmelee (1956) as C. trifolii f. sp. gladioli) with curved conidia (the third cell from the base is swollen and convex on one side). 85/0.95 92/1.0 100/1.0 -/0.88 100/1.0 99/1.0 100/1.0 -/0.97 80/0.98 100/1.0 -/0.81 100/1.0 Curvularia borreriae CBS 859.73 Curvularia pallescens CBS 156.35* Curvularia coatesiae BRIP 24261* Curvularia trifolii CBS 173.55 Curvularia microspora GUCC 6272* Curvularia austriaca CBS 102694* BRIP 71104 IMI 507176* Curvularia gladioli CBS 210.79 Curvularia gudauskasii DAOM 165085 Curvularia harveyi BRIP 57412* Curvularia bothriochloae BRIP 12522* Curvularia akaiiensis BRIP 16080* Curvularia akaii CBS 317.86 Curvularia andropogonis CBS 186.49 Curvularia nanningensis GUCC 11005* Curvularia heteropogonis BRIP 15928* Curvularia deightonii CBS 537.70 Curvularia richardiae BRIP 4371* 0.01 Curvularia tanzanica Phylogenetic tree of selected Curvularia species based on a maximum likelihood analysis of a combined multilocus alignment (ITS and gapdh).

Larss., sp. nov. Etymology. Name refers to its distribution in boreal regions. Classification — Elaphomycetaceae, Eurotiales, Eurotiomy- cetes. Ascomata subglobose, 1–3 cm diam. Peridial surface first yel- lowish brown to orange brown, with age greyish brown with a covering of dense small pyramidal papillae, in places fragile and more or less farinaceous, found solitary or in small groups, no conspicuous hyphal mat or hyphal crust present. Cortex of hya- line to yellowish compacted parallel bundles of regularly septate hyphae, 2–4 µm diam, towards the gleba more loosely interwo- ven and moderately ramified hyphae, 3–5 µm diam. Papillae more strongly yellow pigmented and constructed of intricately interwoven hyphae. Peridium in section fresh up to 3 mm diam, pale pink to violaceous pink, often with slight orange tinges, consisting of hyaline hyphae, 2–5 µm diam, towards the gleba partly covered with abundant extracellular grains of reddish brown pigments. Gleba immature whitish greenish with hyaline hyphae and rounded, thick-walled, 2–2.5 µm diam, peduncu- late asci 40–50 µm diam containing 5–8 ascospores, mature gleba dark brown to black. Ascospores globose, 35–45 µm in KOH incl. ornamentation, 25–30 µm in Hoyer’s medium, with a dense ornamentation of straight to slightly curved spines, 1–2.5 µm long, forming an inconspicuous cheetah pattern with scarce and narrow ‘pathways’. High proportion of ascospores collapsing when mounted in KOH 3 %. Considerably smaller, 14–20 µm, and more pigmented spores, interpreted as aborted spores, are abundantly present among the normal ascospores. Ecology & Distribution — Associated with Picea abies, Pi- nus sylvestris and Betula pubescens in boreal and subalpine forest habitats. It has a more northern distribution range than E. asperulus and E. granulatus, and to date it has only been recorded in Central Sweden, but is likely to occur also in suit- able habitats in neighbouring countries.

Notes — Elaphomyces borealis belongs in a complex of morphologically similar species in subsect. Elaphomyces. It is most closely related to E. asperulus for which an epitype was selected by Paz et al. (2017), and the recently described species E. roseoviolaceus and E. pusillus (Molia et al. 2020). It differs morphologically from E. asperulus in ascospore or- namentation, abundance of aborted spores, and the orange tone of the peridium. Elaphomyces pusillus also has a northern boreal distribution range and occurs in similar habitats but dif- fers in having smaller ascomata and pink to slightly violaceous peridium in section, and smaller spores. Elaphomyces roseo- violaceus is associated with richer and calcareous coniferous mixed forests and has dark pink to bluish violaceous peridium in section and somewhat smaller spores.

ML bootstrap support values are shown at the nodes (BS > 50 %). Notes — Entoloma ammophilum has a characteristic dark brown or brown grey pileus and a polished, bicoloured stipe. It differs from E. glaucobasis, which frequently occurs in the same habitat, by the polished nature of the stipe, and fertile lamellae edge. Furthermore, E. glaucobasis is phylogeneti- cally rather distant in the /Griseocyaneum clade. Within the /Sarcitulum clade, this species resembles E. montanum, which may superficially look similar, but differs clearly in having a sterile, often brown coloured lamella edge, and alpine or boreal distribution. 444 Persoonia – Volume 46, 2021 Entoloma coracis 445Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1241 – 13 July 2021 Entoloma coracis Brandrud, Dima, Noordel., G.M. Jansen & Vila, sp. nov. Etymology. The epithet refers to the dark blackish to violaceous black colour of the basidiomata, like plumage of a raven (Corvus corax). Classification — Entolomataceae, Agaricales, Agaricomy- cetes. Basidiomata medium-sized, collybioid. Pileus 10–35 mm, hemi- spherical to convex expanding plano-convex with involute then deflexed margin, with depressed, rarely umbilicate centre, not hygrophanous, not translucently striate, initially very dark black- ish to violaceous black, with age the bluish tinges fade away, leaving the pileus very dark brownish black, violaceous black or porphyry brown, uniformly coloured, not or slightly pallescent on maturing, entirely tomentose and staying so during develop- ment or breaking up in small squamules. Lamellae, L = 20–30, l = 1–3, moderately distant, adnate-emarginate or with decur- rent tooth, segmentiform to subventricose, white, then with pale pink tinge, with irregular, usually with concolorous edge; rarely spotted black from the start, or becoming spotted blackish with age. Stipe 20–80 × 3–7 mm, relatively long and stout, initially violaceous grey, fading to pale bluish grey, sometimes develop- ing a lilac-pink tinge, much paler than the pileus, not polished, but covered with blue to violaceous longitudinal fibrils, some- times scaly-flocculose at apex, especially in rainy conditions, fibrils with same colour or contrastingly darker than background, with abundant white basal mycelium. Context white. Smell in- significant, taste not recorded.

Notes — Entoloma coracis is one of the E. corvinum look- alikes, with its very dark, opaque, tomentose pileus, white lamellae, and fibrous stipe. Entoloma aranense is a sister spe- cies of E. coracis, less robust, paler, with a lilac-bluish tinged pileus when young, later brown and fibrillose, and a typical subalpine-alpine habitat. Microscopically the differences are minimal. Entoloma porphyrogriseum is also closely related, but differs, e.g., in smaller spores, and not so persistently dark pileus. Phylogenetically (see the phylogenetic tree for E. am- mophilum in Supplementary material FP1240), these three species are rather distant from E. corvinum s.str., as we now interpret it, and they differ from E. coracis, morphologically by the narrower, more sharply angled spores, the serrulatum-type lamella edge, and the habitat. Entoloma corvinum is an alpine species, like the similar E. erhardii, which differs by having smaller spores, and a polished stipe.

Notes — The delicate lilac-blue colour of the basidiocarps as well as the small spores and fertile lamella edge are distinc- tive for E. cyaneolilacinum. It was treated as E. lepiotosme in Noordeloos (2004). However, there are considerable discrepan- cies with the protologue, describing a species with a blackish brown, virgate pileus, reminiscent of a species of Inocybe, a fibrillose stipe surface, a strong smell like that of Lepiota cristata, and larger spores. The lectotype of Rhodophyllus lepiotosmus failed for DNA sequencing. Considering the conflict with the protologue and the lack of molecular data, it was decided to describe the present taxon here as a species in its own right. Morphologically, E. cyaneolilacinum resembles E. violaceo- viride, which has a sterile, brown pigmented lamella edge and often some greenish tinges in the basidiocarp, and has a distant phylogenetic position. Entoloma cruentatum, also phylogeneti- cally distant (see the phylogenetic tree for E. ammophilum in Supplementary material FP1240), has similar spores and fertile lamella edge, but often turns orange-yellow when bruised at the base of the stipe.

Notes — Entoloma isborscanum is characterised by a squa- mulose yellowish brown pileus, a bluish or brownish blue, longitu- dinally striate stipe, rather small spores with distinct 5–7 angles, and a sterile lamella edge consisting of large clavate cheilocystidia arising from the subhymenium. Superficially it resembles E. griseocyaneum, which differs by the absence of cheilocystidia and smaller spores, or E. glaucobasis, which pos- sesses larger, almost nodulose spores (Noordeloos 1992). The holotype specimen was published in Morozova et al. (2015) as E. exile, but this species is sufficiently more slender with distinct greenish glaucous tinges in the stipe.

Notes — Entoloma pseudocruentatum was interpreted as E. cruentatum by Noordeloos (1987, 2004), as similar to E. chalybaeum, with a fertile lamella edge, a glaucous-blue stipe, with the base frequently discolouring yellowish or pale orange. However, there are now reasonable doubts as whether the original diagnosis of Quélet (1886) actually refers to the same species. Entoloma cruentatum is described as a spe- cies with a more or less conical to umbonate, lilac-blue pileus, and a stipe with glaucous bluish stipe with a strong reddening at base. Kühner & Romagnesi (1953) considered it a dubious species, probably in subg. Nolanea. Another option could be that E. cruentatum represents a form of E. exile, a species with rather variable pileus shape and colour, and often a redden- ing stipe base. The concept of Noordeloos (1984) was based on a collection from Scotland, which has many characters in common with the species described here. For this reason, we describe Entoloma cruentatum sensu Noordeloos (1984) as a new species.

Jansen, M.v.d. Vegte & Dima, sp. nov. Etymology. The epithet refers to the modest size of the species. Classification — Entolomataceae, Agaricales, Agaricomy- cetes. Basidiomata small-sized, omphalioid. Pileus 12–18 mm diam, convex with straight or slightly crenulate margin, umbilicate, hygrophanous, deeply translucently striate up to centre, dark brown with obscure sepia-brown centre, finely scaly-virgate, particularly at central part. Lamellae distant, L = 12, l = 1–3, arcuate-deeply decurrent, pale brown with pinkish hue, with concolorous, entire edge. Stipe 35–30 × 1–1.5 mm, slightly broadened towards apex, pale horn brown, glabrous, polished. Smell and taste indistinct. Spores 9.5–13 × 6.5–8.5 μm, av. 11.3–11.5 × 7.6–8.2 μm, Q = 1.2–1.7, Qav 1.4–1.5, heterodia- metrical, rather regularly 5–7-angled. Basidia 28–53 × 11–11.5 μm, 4-spored, clampless. Lamella edge fertile, cystidia absent. Pileipellis a cutis of broad hyphae with transitions to a tricho- derm, made up of clavate elements, up to 25 μm wide, with both intracellular and incrusting pigment. Clamp connections absent. Habitat & Distribution — Gregarious on plant debris, amongst grasses and Sphagnum in unfertilized hayfield. Known only from the type locality in The Netherlands. Typus. the NetherlaNdS, Prov. Gelderland, Groesbeek, de Bruuk, 17 Sept. 2018, Marjon v.d. Vegte & G. Jansen C173-6268 (holotype L0608054, ITS and LSU sequences GenBank MW934594, MycoBank MB 839226). Additional material examined. the NetherlaNdS, Prov. Gelderland, Groesbeek, de Bruuk, 2 Sept. 2018, G. Jansen, C173-6195 (L0607607, not sequenced). Notes — This small omphalioid species was initially identified as Entoloma nigellum sensu Orton (1960), a concept accepted by Noordeloos (2004). The Dutch specimens are very likely the same as Orton’s with their dark, translucently striate pileus, distant, decurrent lamellae, polished stipe, large spores and clampless hyphae. However, when comparing the original diag- nosis of this poorly known species it became clear that Quélet’s Eccilia nigella (Quélet 1886) strongly deviates in habit, in having a not translucent, almost black pileus, and a dark stipe, which sometimes has a bluish tinge. It is therefore rather question- able whether we can adopt the epithet ‘nigellum’ for our taxon. Quélet’s species could well stand for another, dark coloured species in the /Rusticoides clade and type material is not exis- tent. For the time being, it therefore seems prudent to consider Eccilia nigellum as a nomen dubium. Entoloma subpusillum is similar, differing in having a non-translucent, not glabrous but uneven-rugulose pileal surface. Two other apparently similar species, viz., E. pseudonigellum and E. rickenelliformis, differ both in having a dark, not translucent pileus, differently sized and shaped spores, and abundant clamp-connections. The type sequence of E. pseudonigellum cluster distantly, in the /Undati clade, while DNA sequencing of the type of E. rickenelliformis proved unsuccessful. Several questions therefore remain un- answered in this group. Entoloma pudens is described as new, based on well-annotated material and molecular sequence data (see the phylogenetic tree for E. ammophilum in Supplementary material FP1240). Colour illustrations.

Pileipellis cutis with transition to a trichoderm of cylindrical to slightly inflated hyphae 8–20 μm wide with inflated terminal elements and dark intracellular pigment, brownish in KOH. Caulocystidia 35–100 × 5.5–10 μm, as chains of cylindrical or inflated elements, usually with tapered terminal cells. Brilliant granules present. Clamp connections absent. Habitat & Distribution — In small groups on soil in subalpine grasslands. Known from Russia (Caucasus). Typus. ruSSia, Karachaevo-Cherkesia Republic, Teberda Nature Reserve, Arkhyz site, near the waterfall, N43.558889° E41.301389°, alt. 1 390 m a.s.l., 17 Aug. 2009, O. Morozova (holotype LE312483, ITS and LSU sequences GenBank MW934593 and MW934255, MycoBank MB 839228). Notes — Entoloma subcoracis belongs to the form-group of E. corvinum s. auct. including taxa such as E. coracis (also described in present paper) and E. porphyrogriseum charac- terised by blackish blue basidiocarps. Entoloma subcoracis is characterised by the voluminous cheilocystidia, and fusiform, septate caulocystidia. The characteristic large cystidia are shared with the North American E. subcorvinum (Hesler 1967, Noordeloos 1988). Both species seem, however, to be geo- graphically separated. Unfortunately, no DNA sequence data are available for the holotype of E. subcorvinum.

Fungal Planet 1248 – 13 July 2021 Eremothecium peggii R.G. Shivas, Marney, Cunningt. & Y.P. Tan, sp. nov. Etymology. Named after Kenneth G. Pegg, an eminent Australian plant pathologist, from whose garden the fungus was first collected. Classification — Eremotheciaceae, Saccharomycetales, Saccharomycetes. Mycelium composed of filamentous hyphae, budding cells lacking. Hyphae coenocytic without true septa, undulate or straight walls, with abundant localized dense cytoplasmic regions, 2–9 µm wide, branches often at right angles, hyaline. Asci form directly from hyphae, mostly intercalary and aligned in chains, occasionally terminal or lateral, with a narrow base 3–5 µm wide, when immature cytoplasmic contents distinctively concave at base and separate from hyphal cytoplasm, irregu- larly sinuous to clavate-cylindrical, rounded at apex, hyaline, (20–)40–75(–120) × 8–18 µm, with 16 or 32 ascospores, splits irregularly. Ascospores acicular, straight or slightly curved, 15–21 × 1.5–2 µm, hyaline, widest at a narrow faint hyaline band near the middle, narrow to a truncate base less than 0.5 µm wide, arranged in the ascus in two (or four) opposed bundles of eight spores with apices pointed at the poles, germinate by a perpendicular or oblique germ tube at swollen mid-point. Culture characteristics — On malt yeast extract peptone glucose agar after 4 wk in the dark at 25 °C, colonies 2–3.5 cm diam, flat, dull, dry, translucent, margin filamentous and irregu- lar, raised, tenacious in their consistency.

Notes — The Eremotheciaceae is a monophyletic group of species that have needle-shaped ascospores (Kurtzman 1995). Eremothecium contains five species, E. ashbyi, E. coryli, E. cymbalariae, E. gossypii and E. sinecaudum, that are charac- terised by acicular ascospores (https://theyeasts.org, Kurtzman & Robnett 2003). One of these, E. coryli, has been associated with fruit dry rot in cultivated and indigenous Citrus in Australia (Shivas et al. 2005). During that study, Eremothecium peggii was isolated from fruit with dry rot of Citrus australis (Dooja, round lime), which is native to subtropical rainforest in New South Wales and Queensland, Australia. All species of Ere- mothecium are considered as plant pathogens, although the pathogenicity of E. peggii as the cause of fruit dry rot has not been demonstrated. Based on a BLASTn search of NCBI GenBank nucleotide data- base, the closest hit against LSU sequences ex-type speci- mens were E. cymbalariae (strain NRRL Y-17582, GenBank NR_042628.1, Identities 854/884 (97 %), Gaps = 4 (0 %)); E. si- necaudum (strain ATCC 58844, GenBank XR_001930265.1, Identities 867/898 (97 %), Gaps = 5/898 (0 %)); and E. gossypii (strain CBS 109.26, GenBank NG_063967.1, Identities 863/899 (96 %), Gaps = 5/899 (0 %)).

Notes — The family Extremaceae includes fungi that are ecologically highly diverse ranging from extremophilic, rock inhabiting and acidophilic members such as Extremus, the generic type, to lichenicolous, epiphyllous, endophytic, sapro- bic or plant pathogenic genera (Quaedvlieg et al. 2014). The new genus Extremopsis is introduced to accommodate sterile strains of a root endophyte isolated from surface-sterilised, asymptomatic roots of plants used as bait inoculated with root-associated soil. The three strains of E. radicicola did not sporulate in any of the different culture media used including MEA, PDA, MCA or Water Agar supplemented with wooden toothpicks, but they produced abundant chlamydospores in all media. Their ITS and partial LSU sequences were nearly identical except for a single gap at position 128 of alignment in the case of the ITS of both CBS 147117 and P6514, and two bp differences in the LSU of the latter. Phylogenetically, they form a strongly supported monophyletic group in Extremaceae sister to the genus Extremus but with low support. Moreover, although originally identified as ‘Devriesia’ sp., they group distant from Devriesia s.str. in Teratosphaeriaceae represented by D. stauro- phora, the generic type (Meng et al. 2017). Interestingly, two other strains also named ‘Devriesia’ sp., NG_p52, isolated during a study of gene expression of fungal nitrate reductases in agricultural soils from Austria (Gorfer et al. 2011); and MI63, isolated from soil in Germany, grouped within the Extremopsis clade and seem conspecific with E. radicicola, expanding the known distribution of the genus from southern Spain to other localities across Europe. Based on a megablast search of NCBIs GenBank nucleotide data base, the closest hits of Extremopsis radicicola (CBS 147117) using the ITS sequence are ‘Devriesia’ sp. NG_p52 (GenBank HQ115717.1; Identities = 232/232 (100 %), no gaps), ‘Devriesia’ sp. MI63 (GenBank MW268825.1; Identities = 230/232 (99 %), no gaps) and a melanised limestone asco- mycete CR-2004 TRN80 (GenBank AY559340.1; Identities = 222/232 (96 %), two gaps (0 %)).

Pham, A.V. Alexandrova & O.V. Morozova, sp. nov. Etymology. The epithet refers to bright yellow colour of the basidiomata and orange margin of tubes, from Latin ‘aurantius’ (orange) and ‘flavus’ (yellow). Classification — Boletaceae, Boletales, Agaricomycetes. Basidiomata medium sized, boletoid. Pileus 25‒50 mm diam, hemispherical to convex; the surface is mucous to sticky when wet, smooth; the edge overhanging the hymenophore, even, strongly inflexed in young basidiomata; yellow, bright yellow or yellow-orange to orange and dark orange (3A6–8, 4A6–8, 4B5–6; Kornerup & Wanscher 1978). Hymenophore poroid, adnate-emarginate, decurrent with a short tooth on the stipe, slightly depressed around the apex of the stipe, 3–8 mm thick, 1.5–2 times thicker than the context; tubes yellowish to cream, do not change colour if damaged; the pores are rounded to angular, 0.5–1 mm diam, with bright orange drops of exudate on the margin. Stipe 40–90 × 3–7 mm, cylindrical, fusiform or slightly widening towards the base, pale yellow with orange dots above (drops of exudate), bright yellow below the annu- lar zone (if present), smooth, mucous to sticky, solid in upper part, becomes hollow in the lower part. Context yellowish, not changing in the pileus and in the upper part of the stipe, in the lower half turns slightly blue. Smell weak, taste not reported. Basidiospores (10–)11.5–12.5(–14) × (3.5–)4(–4.5) μm, Q = (3.0–)3.1(–3.3), fusiform or nearly cylindrical with weak supra- hilar depression in lateral projection, fusiform in the ventral projection, from yellowish to brownish yellow in KOH, smooth. Basidia 24–36 × 7–10 µm, 4-spored, clavate. Cheilocystidia 45–70 × 4–6 µm, forming a sterile margin, cylindrical, flexuous, thin-walled, with pale yellow content.

Alexandrova & T.H.G. Pham (LE 315617, ITS, LSU and mtSSU GenBank sequences MW784160, MW760389 and MW776412). Notes — Fistulinella aurantioflava is characterised by a bright yellow colouration of basidiomata, a smooth, strongly glutinous surface of pileus and stipe in a wet state, a strongly involved pileus margin, covering the hymenophore of young basidiomata, and a wide hymenophore. Microscopically, smooth fusiform, almost cylindrical spores and lageniform pleurocystidia with yellow content are characteristic. Due to macromorphologi- cal features, F. aurantioflava resembles Pulveroboletus curtisii, described from North America and distributed there. However, the surface of the pileus of the true Pulveroboletus species is pulverulent, and distinct pileal margin veil covers the hymeno- phore when young. Contrary, the strongly glutinous covering of the pileus and stipe makes our species similar to representa- tives of the pink-spored genus Fistulinella (Austroboletoideae), originally described based on a species from Cameroon (Hen- nings 1901). Preliminary molecular analyses suggested this genus to be polyphyletic. Vasco-Palacios et al. (2014), Magnago et al. (2017) and Gelardi et al. (2021) showed that American species of Fistulinella cluster in a statistically strongly supported separate clade with respect to those described from Australia, New Zealand and Asia. However, molecular analyses are re- quired on the generic type, the African taxon F. staudtii to clarify the delimitation of Fistulinella s.str. According to the data of the phylogenetic analysis, our speci- mens are nested within the /Austroboletoideae clade, close to Austroboletus, Veloporphyrellus and the Asian branch of Fistu- linella. Despite the presence of some morphological differences (the absence of a pronounced pink colour of the spores, the presence of yellow-coloured pleurocystidia, and the unusual bright yellow colour of basidiomata), we attribute this species to the genus Fistulinella. Fistulinella aurantioflava differs from Pulveroboletus curtisii (the systematic position of which also requires clarification) by its smaller and narrower spores ((10–)11.5–12.5(–14) × (3.5–)4 (–4.5) µm vs (10.5–)11.2–15(–19) × 4.3–6.5 µm (Singer 1947)), the presence of a bluish discolouration in the lower part of the stem, and geographical distribution. In the GenBank database Pulveroboletus curtisii is represented only by mtSSU and LSU sequences. Our sequences of these markers are very distant from them (mtSSU: 5.35 %; LSU: 7.29–7.39 %).

Ramoconidia de- rived from detached cells of branchlets of upper conidiophores present in older cultures, more irregular, angular and elongated, sometimes apiculate, (5.5–)7–11.5(–15) (av. = 9.1) µm long × (1.5–)2–3(–4) (av. = 2.6) µm wide. Vegetative hyphae smooth, hyaline, thin-walled, regularly septate, 1–2 (av. = 1.7) µm wide; rarely, larger, thin-walled, globose cells present. Culture characteristics — (in darkness, 20 ± 2 °C). On oat- meal agar (OA) colonies dense, margin irregular, undulating, elevated in the centre, initially creamy, later beige, slightly or- ange in the centre in older colonies, with very sparse patches of white, low aerial mycelium, reaching 2(–2.5) cm in 2 mo. On potato dextrose agar (PDA) and malt extract agar (MEA) averse creamy, yellowish in older cultures, reverse yellowish, reaching 1.5(–2) cm in 2 mo. On cornmeal agar (CMA) cultures tiny, with white, snow-like, fluffy aerial mycelium, vegetative mycelium sparse and thin. On CMA radiating needle-like crystals were noted on the surface of the mycelium, 20–40 (av. = 31) µm diam.

Notes — Hyalodendriella bialowiezensis is similar to sub- hyaline cladosporium-like fungi – Hyalodendriella betulae, Ra- chicladosporium, Hormiactis, and members of obsolete genus Hyalodendron (now in Ramularia and Apiotrichum). However, conidia of H. bialowiezensis do not have coronate scars (like Ramularia or true Cladosporium), and are always aseptate (unlike Hormiactis). Moreover, conidiophores and conidia of H. bia lowiezensis are consistently hyaline, while abovemen- tioned taxa are at least partially subhyaline or brownish. Young terminal limoniform conidia of H. bialowiezensis sometimes detach in chains still connected with thin thread of not fully di- vided cell wall in a manner similar to Oidiodendron griseum. Al- though H. bialowiezensis is related to apothecia-forming Helo- tiales, no associated sexual morph was recorded. Hyalodendriella betulae and H. bialowiezensis have very simi- lar limoniform conidia with distinctly apiculate ends, that in both cases are formed in chains. However, in case of H. bi- alowiezensis conidia are significantly larger (5–7 µm long, in H. betulae 0.5–1 µm) (Crous et al. 2007a). Conidiophores of H. bialowiezensis correspond with macroconidiophores (or type B conidiophores) of H. betulae in having, albeit rarely, conidio- genous cells with multiple loci (up to three in H. bialowiezensis). Interestingly in both species undetached conidia seem to elon- gate from the conidiophores in some cases. While they remain attached to microconidiophores of H. betulae, they infrequently break up as ramoconidia in H. bialowiezensis. Hyalodendriella is placed either in Pezizellaceae, Helotiales (Johnston et al. 2019) or in Hamatocanthoscyphaceae, which in the classification of Ekanayaka et al. (2019) does not belong to Helotiales s.str. Based on a megablast search of NCBIs GenBank nucleotide database the most similar, identified fungal sequences belong to Hyalodendriella betulae strain CBS 261.82 (LSU sequence, 96 % identity), Chalara constricta and Chalara hughesii (SSU sequences, 95 % identity). ITS sequences of H. bialowiezen- sis are distantly similar to other Helotiales (90 % identity to Xenopolyscytalum and various unidentified Hyaloscyphaceae sequences for ITS). The maximum likelihood tree was constructed with RAxML- NG (Kozlov et al. 2019) on a partitioned alignment including SSU, 5.8S and LSU rDNA, mtSSU and protein coding tef1-α, rpb1, rpb2, β-tub and mcm7 sequences, being an excerpt of the combined datasets of Han et al. (2014) and Johnston et al. (2019). The dataset contained 35 taxa and a total of 7 873 characters of which 1 919 were variable. Bootstrap support values at branches were obtained by generating 1 000 bootstrap replicates. The tree is rooted with Leotia lubrica belonging to Leotiales. Colour illustrations.

Basidia predominantly 2-spored, sporadically 1-spored, 20–32 × 4.5–6 μm, narrowly clavate. Cheilocystidia abundant, 34–59 × 9–18(–27) μm, utriform, broadly lageniform with subcapitate apex, some proportion almost lecythiform with broad capitula, intermixed with broadly clavate, urniform or subcylindrical ones, hyaline, thin-walled.

Clamp connections present. Habitat & Distribution — Growing in small groups or solitary on rotted wood of Betula pendula. So far known only from type locality. Typus. Russia, Krasnoyarsk Territory, Sayano-Shushenskiy State Bio - spheric Nature Reserve, the mouth of the Sarly River, N52°09'55.5" E92°18'43.9", floodplain birch forest, on rotted wood of Betula pendula, 16 Aug. 2020, V. Malysheva (holotype LE 313638, ITS and LSU sequences GenBank MW725580 and MW760390, MycoBank MB 839059). Notes — Hydropus lecythiocystis is characterised by its pruinose and dark greyish brown pileus with slight touch of olive, cheilocystidia of variable shape with presence of lecythiform elements, 2-spored basidia, predominantly subcylindrical, allan- toid or dacryoid, amyloid basidiospores, and lignicolous habitat. Based on morphological characters it resembles H. marginellus (Bas 1999, Læssøe 2008), but differs from the latter by having concolorous lamellae edge, exclusively 1–2-spored basidia, shorter cheilocystidia with present of distinctive lageniform ones with subcapitate apex, and growing on wood of deciduous trees. Phylogenetically, H. lecythiocystis and H. marginellus turned out to be closely related species. In the phylogenetic tree, H. lecy- thiocystis formed a branch close to European collections of H. marginellus but not to North American ones. However, the dissimilarity of their nrITS sequences reaches more than 2 %, and together with strong micromorphological differences, it is enough to consider them as different species.

Pavlík, BRACR 33659, ITS and LSU sequences GenBank MW471671 and MW471669, BOLD ITS sequence FULGE002-20. Notes — Hygrocybe fulgens is characterised by a dry, squa- mulose applanate pileus, dry, smooth and broad stipe, pileipellis a trichoderm, ellipsoid to oblong spores, and by a size and colour of whole sporocarps, which are usually orange yellow, often with golden yellow stipe and darker (almost scarlet red) central part of pileus. Due to these features, this species fits well with the concept of the subgenus Pseudohygrocybe sec- tion Coccineae and subsection Squamulosae (Lodge et al. 2014). Based on macromorphological features, the most similar species to Hygrocybe fulgens are H. calciphila, H. miniata, H. reidii and H. substrangulata. Hygrocybe calciphila, differs by typical subglobose to broadly ellipsoid spores and smaller basidiomata. Macroscopically, H. fulgens and H. calciphila are very similar, but sporocarps of H. fulgens are mostly much larger and robust. Hygrocybe miniata is characterised by triangular or pear-shaped spores, pileus without darker central part and also by a thinner stipe (usually to 5 mm broad). Hygrocybe reidii is another macroscopically similar species to H. fulgens, differing by a honey-like smell and smooth, orange-red coloured pileus. Hygrocybe substrangulata differs from other mentioned Hygrocybe species by much larger spores (up to 14.5 µm) and sometimes decurrent lamellae (Boertmann 2010). All above mentioned species grow in central Europe in the unimproved, sometimes grazed or mowed grasslands with Nardus stricta or Agrostis spp., but H. fulgens was found in a different type of grassland, where Leontodon hispidus was a dominant plant. In the maximum likelihood tree based on the ITS sequences H. fulgens is positioned on a separate branch close to the clade of subsection Squamulosae, which is consistent with the results of macro- and micro-character observations.

Etymology. In honour of Prof. Luis Zaror, prominent Chilean mycologist and writer; active promoter of medical technology and mycology in South America, and long-time inhabitant of Teja island, where this species was first collected. Classification — Nectriaceae, Hypocreales, Sordariomy- cetes. Conidiophores of two types: a) solitary, erect or prostrate, arising laterally from aerial and substrate mycelium, commonly formed on dense and twisted hyphal ropes, septate, 33.5–482 μm long, unbranched or sparsely, irregularly branched, bearing terminal and solitary conidiogenous cells; or b) densely packed in sporodochia, formed on the substrate surface, simple, rarely branched, bearing terminal single conidiogenous cells or whorls of up to three conidiogenous cells; conidiogenous cells mono- phialidic, subcylindrical to cylindrical, gently tapering towards apex, with inconspicuous periclinal thickening and short, flared apical collarettes, those formed on aerial conidio phores 24–58.5 μm long, 2.5–4 μm at the widest point; phialides on sporodochial conidiophores 20–27 μm long, 2.5–3.5 μm at the widest point. Microconidia rarely observed, formed on aerial conidiophores, 0(–1)-septate, subglobose, ellipsoid to long clavate, (8–)10–15(–16) × (3–)4–5.5 μm (av. = 12.2 × 4.6 μm). Macroconidia produced abundantly on aerial and sporodochial conidiophores, 1–2(–3)-septate, cylindrical with both ends more or less obtusely rounded, straight or slightly curved; 1-septate conidia: (16.5–)20.5–28.5(–32) × (4.5–)5.5–6.5(–7) μm (av. 24.5 × 6 μm); 2-septate conidia: (26–)29–35(–41.5) × 5–7(–8) μm (av. 32.4 × 6.3 μm); 3-septate conidia: (28–)30–39(–40.5) × 6–7.5 μm (av. 34.6 × 6.8 μm); overall: (16.5–)23.5–34(–41.5) × (4.5–)5.5–7(–8) μm (av. 28.9 × 6.2 μm). Chlamydospores rarely produced, doliiform, subglo- bose to globose, 7–14 μm diam, thick- and smooth-walled, terminal or intercalary; solitary, in short chains or forming sparse clusters, hyaline at first, quickly becoming golden yel- low to brown.

Ecology & Distribution — Associated with Salix spp. and Betula pubescens subsp. czerepanovii in open areas on some- what calcareous sandy soils. Basidiomata so far only known from the subalpine zone of Norway and alpine zone of Swe- den, where it grew amongst Salix herbacea. In addition, ITS sequence data generated from soil samples in a locality in the alpine zone shows that it also occurs in Austria. Typus.

Vauras, TUR-A 204346, ITS-LSU sequence GenBank MW617341. Notes — Inocybe norvegica belongs in the I. lacera group. It is a rather small species characterised by hemispherical pileus which is subsquamulose to recurvately squamulose and often with indistinct velipellis. Microscopically it shows rather dark and ellipsoid spores, often with indistinct germ-pore. Inocybe helobia (Kuyper 1986, Bandini et al. 2020) grows like I. nor- vegica with Salix and has similarly dark spores, but they are more amygdaliform and angular, and with larger average Q (1.9–2.3 vs 1.7 in I. norvegica). Further, it has pleurocystidia with often acute apex and thicker and mostly more yellow walls, and grows mainly in moist habitats. Inocybe impexa (Kuyper 1986) is another species with rather darker spores. It is stouter and has larger spores, with larger average Q (2.0–2.3). It grows on sandy seashores, but also in inland sand-pits, and even in alpine localities with Salix herbacea. Other smooth-spored taxa of the Inocybe lacera group (I. lacera, I. lacera var. hetero- sperma and I. pluppiana) have paler spores. Colour illustrations.

Bera, A. Ghosh, Nuytinck & Verbeken, sp. nov. Etymology. In honour of Dr Kanad Das for his invaluable contribution to the systematics of Russulaceae in the Indian Himalayan Region. Classification — Russulaceae, Russulales, Agaricomycetes. Pileus 30–85 mm diam, hemispheric to convex when young, gradually becoming planoconvex with a broad shallow de- pressed centre; surface moist, smooth, velvety, faintly rugulose towards the margin, yellowish white (1A2) and paler, with some irregular darker spots, but turning orange white to pale orange (5A2–4) to ochraceous and darker on bruising and even brown- ish on maturity; cracked at several places towards the margin in mature basidiomata; margin entire, incurved when young, remaining incurved through maturity. Lamellae adnate to sub- decurrent, close to rather crowded (20 L+l /cm at pileus mar- gin), dichotomously forked; lamellulae present in 3–4 series; yellowish white (2–3A2); edge entire, smooth, concolorous. Stipe 25–95 × 15–30 mm, central, cylindrical but sometimes twisted near the base; surface velvety, strongly rugulose locally; concolorous to the pileus, when bruised turning pale orange to light orange (5A3–4) to ochraceous and darker. Context thick in pileus and stipe, yellowish white (1–2A2), almost immediately turning pale orange on bruising, greyish green (1D4) in guaiac, orange (5A6–7) in FeSO4 and immediately yellowish in KOH. Latex yellowish white, copious, unchanging on cut lamellae. Taste very acrid. Odour fruity. Spore print not recorded. Basidiospores 5.8–6.7–8.2(–9.1) × 4.7–5.6–6.7 μm, n = 30, Q = 1.04–1.19–1.32(–1.44), usually globose to ellipsoid; orna- mentation amyloid, up to 0.6 μm high, composed of isolated irregular warts which are sometimes aligned or connected by lower lines but never forms any reticulation; suprahilar spot ina- myloid. Basidia 39–56.8 × 9.0–11.8 µm, clavate to subclavate, 4-spored; sterigmata 2–3 × 1.4–2 µm. Pleuromacrocystidia abundant, 47–69 × 5.4–9 µm, emergent up to 32 µm, cylindrical to subcylindrical with rounded, subfusoid to subcapitate apices, thin-walled; content dense, granular to crystalline. Pleuropseudo- cystidia abundant, 2.5–3 µm wide, emergent up to 12 µm, cylindrical, with rounded apex. Lamellae edge fertile with ba- sidia, basidioles and cystidia. Cheilomacrocystidia abundant, 45–61 × 4.6–6.6 µm, emergent up to 40 µm, subcylindrical with rounded, subfusoid to subcapitate apices, thin-walled; content dense, granular to crystalline. Subhymenium up to 20 µm thick, cellular. Hymenophoral trama composed of lactifers and few nests of sphaerocytes connected with hyphae. Pileipellis a trichoepithelium, up to 136 µm thick; suprapellis composed of ascending elements, 15.4–22.1 × 2.7–3.8 μm, cylindrical to subfusiform, septate; subpellis multicellular composed of isodiametric cells of 8.6–12.8 × 4.0–11.1 μm; pileocystidia present, 22–26.5 × 5–10 μm, cylindrical to subcylindrical, content dense, crystalline. Stipitipellis a trichoepithelium, up to 52.2 μm thick; suprapellis composed of septate ascending elements arising from distinct multicellular subpellis of mostly isodiametric cells; caulocystidia present, 16–26 × 5.5–6.6 μm, mostly cylindrical, content dense, crystalline. Clamp connec- tions absent in all tissues. Sporocarp characteristics — Lactifluus kanadii differs from the other members of L. sect. Piperati due to the clear change of basidiomata colour from yellowish white when young to pale orange to ochraceous and darker to even brownish on maturity and when bruising, the trichoepithelium nature of pileipellis and stipitipeliis and in sequence data of the nrITS, LSU and rpb2 markers.

Additional material examined. iNdia, Arunachal Pradesh, Namchu, Dirang, West Kameng, under Castanopsis sp. (Fagaceae) in temperate broadleaf forest, 6 Aug. 2019, I. Bera, IB 19-025, CAL 1827, ITS, LSU and rpb2 se- quences GenBank MW295838, MW295840 and MW354673. Notes — The combination of macro- and micromorphologi- cal characters like the smooth, yellowish white, firm sporocarp, crowded lamellae, yellowish white, copious, latex, acrid tasting context and two-layered pileipellis with the hyphal suprapellis and the cellular subpellis with pileocystidia undoubtedly place L. kanadii in L. subg. Lactifluus sect. Piperati (Hesler & Smith 1979, Heilmann-Clausen et al. 1998, De Crop et al. 2014). In the field, it can be misidentified as L. piperatus (as the name has been misapplied several times to many lookalike speci- mens worldwide), but L. kanadii easily distinguishes itself due to its much smaller pileus (30–85 mm diam), striking colour change of the basidiomata from the yellowish white in young sporocarps to light orange to ochraceous and darker and even brownish on maturity, its context that immediately turns yel- lowish in KOH, much thicker pileipellis (up to 137 µm thick) and the trichoepithelial nature of both the pilei- and stipitipellis. Morphologically, L. glaucescens can also be confused with L. kanadii. But L. glaucescens can be distinguished on account of its latex turning greenish on drying, subglobose to ellipsoid basidiospores (Q = 1.05–1.26–1.33–1.45) with much shorter ornamentation (up to 0.2 µm high), longer pleuromacrocystidia (60–90 × 7–10 µm) and cheilomacrocystidia (55–70 × 7–9 µm) (Heilmann-Clausen et al. 1998). The Indian species Lactifluus dwaliensis (originally described as Lactarius dwaliensis) can easily be distinguished from L. kanadii due to its much more robust and larger sporocarps (pileus 84–130 mm diam, stipe 50–145 × 17–30 mm), rather distant lamellae and latex turning greenish yellow on exposure (Das et al. 2003, Verbeken et al. 2012).

Etymology. Name refers to the host genus Fagus on which wood this fungus was collected. Classification — Irpicaceae, Polyporales, Agaricomycetes. Basidiomata annual, resupinate, poroid, separable to slightly adnate, effuse, brittle when dry, up to 1 mm thick and 3 cm wide. Margin white, well-distinguished, up to 2 mm wide, thinning out, cottony to fimbriate. Pore surface pale greyish brown with light pinkish brown tints and yellowish beige close to the edge. Pores 3–4 per mm, round to angular and slightly elongate, with entire dissepiments. Subiculum thin, white to cream, soft and cottony, up to 0.5 mm thick. Tube layer concolorous with pore surface. Hyphal system monomitic; generative hyphae simple-septate. Subicular and tramal hyphae 3–4.5 μm diam, hyaline, slightly to distinctly thick-walled, encrusted with numerous sandy-like crystals, occasionally ampullate, strongly ramified, loosely inter- woven, often branched at right angles. Subhymenial hyphae up to 2.5–3 μm diam, hyaline, thin-walled, smooth, compactly interwoven. Cystidia 25–35 × 3.5–4.5 μm, rather common, thin- walled, not encrusted, partly projecting above the hymenium up to 15 μm long, almost cylindrical to fusoid. Basidia 16–20 × 4.5–5 μm, clavate, with a simple septum at the base, 4-sterigmate. Basidiospores (3.9–)4.0–4.9(–5.3) × (1.9–)2.0–2.3(–2.4) μm, n = 30, L = 4.37, W = 2.15, Q = 1.83–2.29, smooth, hyaline, thin- walled, suballantoid to ellipsoid, inamyloid, non-dextrinoid, mostly with one oil drop. Habitat & Distribution — On dead fallen Fagus orientalis branches, in a beech forest of piedmont Dagestan (North- Eastern Caucasus, Russia). Hitherto only known from the type locality. Typus. ruSSia, Republic of Dagestan, Tabasaransky District, 1 850 m south- westward from the Yersi settlement, 690 m a.s.l., N42°00'02" E48°00'15"; on fallen dead branches of Fagus orientalis (Fagaceae) in beech forest without any herbal undergrowth, 12 Sept. 2020, S. Volobuev & A. Ismailov (holotype LE F-334408, ITS and LSU sequences GenBank MW673659 and MW673660, MycoBank MB 839242). Notes — Meruliopsis faginea, having resupinate basidio- carps with a greyish to pinkish brown poroid hymenophore, monomitic hyphal system and simple-septate hyphae, belongs to the genus Meruliopsis, distinguished as a well-supported clade in a recent three-gene phylogenetic study (Chen et al. 2020). Our Maximum Likelihood analysis of ITS sequences showed that M. faginea forms a neighbouring branch to M. lepto cystidiata, and according to a BLAST search of NCBIs GenBank nucleotide databases the similarity of these sequen- ces is insufficient to consider M. faginea and M. leptocystidiata conspecific. The comparison results of the newly generated nrITS sequence of M. faginea with M. leptocystidiata sequences are as follows: GenBank LC427013; Identities = 517/552 (94 %), 17 gaps (3 %); LC427012; Identities = 511/546 (94 %), 17 gaps (3 %); LC427012; Identities = 551/603 (91 %), 27 gaps (4 %). Moreover, M. faginea has larger basidiospores (mostly 4–4.9 × 2–2.3 μm vs 3–4 × 1.5–2 μm in M. leptocystidiata), wider pores and a more intensive colour of the pore surface. Morphologi- cally, M. faginea is close to M. violacea in shape and size of spores, as well as hyphal structure, but the latter species differs by having violet or purple violet tints of the pore surface and lacking cystidia.

Notes — During a survey of endophytic yeast biodiversity, two conspecific and asexual yeast strains belonging to the genus Metschnikowia were isolated from internal tissues of jujube fruits. Many new species of Metschnikowia have been isolated before from plant-insects associations (Lachance 2016). The nrDNA sequences of studied strains have a num- ber of nucleotide substitutions and indels between described species. Based on a blastn search of NCBIs GenBank nucleo- tide database, the closest hit using the ITS sequence is Metschnikowia caudata (CBS 13651T, GenBank KM233175; Identities = 236/287 (82 %), 16 gaps (5 %)); using the LSU se- quence these are Candida hainanensis (AS2.3478T, GenBank EU284103; Identities = 290/326 (89 %), 12 gaps (3 %)) and C. touchengensis (CBS 10585T, GenBank EU284103; Iden- tities = 310/355 (87 %), 14 gaps (3 %)); using tef1 it is C. hai- nanensis (NRRL Y-48715, GenBank MG050955; Identities = 817/850 (96 %), no gaps). Results of the phylogenetic analysis of the LSU and tef1 combined dataset as proposed by Kurtz- man et al. (2018) suggest that studied strains belong to a new species closest to the M. caudata clade, including both asexual and sexual yeasts. Metschnikowia taurica sp. nov. differs from the phylogenetically closest species by 4–12 physiological characteristics. Among common distinctions, the new species is not able to assimilate glycerol and no growth in the presence of 10 % NaCl. Colour illustrations. Russia, Alushta, the jujube fruits on local market.

Notes — Microdochium ratticaudae was discovered during a survey in Australia for fungi on leaves and stems of introduced giant rat’s tail grasses (Sporobolus natalensis and S. pyrami- dalis), which have become weedy in pastures. Microdochium ratticaudae is currently under investigation by us as a potential biological control agent for these exotic grasses in Queensland. The genus Microdochium contains about 50 species, with se- veral that are plant pathogens of grasses (Hernández-Restrepo et al. 2016, Liang et al. 2019, Marin-Felix et al. 2019b). A multilocus phylogenetic analysis of the ITS, LSU and rpb2 loci placed M. ratticaudae in a monophyletic branch sister to M. dawsoniorum, and close relatives of M. albescens, M. citrini- discum, M. paspali, M. seminicola and M. sorghi. A blastn search of NCBIs GenBank shows that the closest hits using the ITS sequence were M. trichocladiopsis (GenBank KP858998; Identities 493/516 (96 %), seven gaps (1 %)), M. tai- nanense (GenBank NR_145248; Identities 491/515 (95 %), seven gaps (1 %)) and M. dawsoniorum (GenBank MK966337; Identities 497/526 (94 %), ten gaps (1 %)). A blastn search of NCBIs GenBank shows that the closest hits using the LSU se- quence were Sporothrix sclerotialis (GenBank MH872840; Iden- tities 852/864 (99 %), two gaps (0 %)), M. tainanense (Gen- Bank KP858931; Identities 853/860 (99 %), one gap (0 %)) and M. bolleyi (GenBank MH869857; Identities 849/864 (98 %), three gaps (0 %)). A blastn search of NCBIs GenBank shows that the closest hits using the rpb2 sequence were M. albe- scens (GenBank KP859103; Identities 710/839 (85 %), no gaps) and M. bolleyi (GenBank LT990643; Identities 743/891 (83 %), no gaps).

The dataset contained 53 taxa and a total of 1 546 cha racters of which 569 were variable. Partitioning scheme and substitution models for analyses were as follows: the GTR+I+G model was proposed for the ITS1 and ITS2; K80+I for the 5.8 region and TrNef+I+G for the LSU region. The tree was constructed with IQ-TREE v. 1.4.4 (Nguyen et al. 2015). Support values at branches were obtained from 1 000 bootstrap replicates.

Notes — BLAST analysis with the ITS sequence of N. okla- homaensis showed greatest similarity with N. placitae (~94.1 %), N. catenatus (93.7 %) and N. aloes (~92.9 %). Neophaeococcomyces oklahomaensis commonly produces globose to moniliform conidia, (4–)5–7(–8) × 4–7(–8) μm diam, compared to ellipsoidal to globose conidia in N. aloes, 4–7 × 3.5–6.5 µm diam, globose in N. catenatus, 5–9 µm diam, and narrowly ellipsoidal with obtuse apex and subtruncate base in N. placitae, (4–)5–6 × 3–4 µm diam. Rock inhabiting fungi are dispersed through the diversity of the Trichomeriaceae and accommodated mostly in genera Anthra- cina, Bradymyces, Knufia and Lithohypha (Hubka et al. 2014, Isola et al. 2016, Sun et al. 2020). The genus Neophaeococ- comyces was erected by Crous et al. (2015b) to accommodate the epiphytic N. aloes and the rock-inhabiting / airborne N. cate- natus. Here we describe another rock-inhabiting member of the genus, N. oklahomaensis, and transfer the epiphytic species, Exophiala placitae (Crous et al. 2007c), to Neophaeococco- myces. The phenotypic differentiation of species and genera of rock-inhabiting fungi across different orders and families is almost impossible due to convergent evolution associated with adaptations to identical extreme environments. Reliable differentiation is possible only by means of molecular methods. Neophaeococcomyces placitae (Crous & Summerell) Hubka & Jurjević, comb. nov. — MycoBank MB 839245 Basionym.

Alignment comprised 25 ingroup isolates belonging to 22 Neosetophoma species and one outgroup taxon (Brunneomurispora lonicerae KUMCC 18-0158). The obtained Neosetophoma isolate formed a branch sister to N. phragmitis with high bootstrap support (ML = 90/100). The isolate was considered to be the newly described species named here as Neosetophoma buxi sp. nov. Maximum likelihood bootstrap support values less than 50 % are not shown. The tree was built using MEGA v. 7.0 (Kumar et al. 2016). The alignment and tree are available in TreeBASE (Submission ID: 27824). Notes — In the phylogenetic analysis based on ITS and LSU sequences, N. buxi formed a branch sister to N. phragmitis with high bootstrap support (ML = 90/100). Neosetophoma buxi can be easily distinguished from N. phragmitis by size of conidia (7.01–)8.46–9.81(–12.03) × 2.7–3.01 μm in N. buxi vs (3–)4–5(–6) × 2 μm in N. phragmitis. Moreover, N. buxi produce smaller conidiomata 120–140 μm diam vs 180–200 μm diam in N. phragmitis.

Sclerotio- rum ser. Sclerotiorum based on 1 739 aligned nucleotides (combined BenA, CaM and RPB2 sequences). Strain and GenBank accession numbers used in the analysis can be found in Houbraken et al. (2020). Analysis performed using RAxML v. 8.2.12 (Stamatakis 2014). Bootstrap 1 000 re-samplings; only bootstrap support values above 70 % are presented at the nodes and branches of > 95 % are thickened. Penicillium herquei and P. adametzioides were used as outgroup. The scale bar indicates the expected number of substitutions per site. Notes — A homology search of ITS, BenA, CaM and RPB2 sequences of P. ferraniaense CBS 147595 against an in-house reference sequence database containing data of all accepted Penicillium species (Houbraken et al. 2020), retrieved P. dae- jeonium (ITS, 99.3 %; BenA, 97.1 %; CaM, 95.6 %) as most similar species; no RPB2 reference sequences of P. daejeonium are present on GenBank or in the in-house reference sequence database. The close relationship between P. ferraniaense and P. daejeonium is confirmed by phylogenetic analysis. Phylo- genetic analysis also shows that P. ferraniaense belongs to ser. Sclerotiorum of sect. Sclerotiorum. Like other sect. Sclero- tiorum species, the conidiophores of P. ferraniaense are also predominantly monoverticillate (in contrast to the biverticillate conidiophores of ser. Herqueorum species) and the strains do not produce coloured, soluble pigments (in contrast to ser. Adametziorum species). Compared to P. daejeonium, P. fer- raniaense grows more slowly on CYA (25–28 vs 36–41 mm), MEA (25–28 vs 30–35 mm) and YES (21–23 vs 33–36 mm), and is able to grow on CYA incubated at 30 °C. 492 Persoonia – Volume 46, 2021 Penicillium uttarakhandense 493Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1265 – 13 July 2021 Penicillium uttarakhandense Rajeshk., N.

Notes — Isolates of Phytophthora kelmanii constitute a well- supported monophyletic group sharing a common ancestor with a clade consisting of P. pseudocryptogea (Safaiefarahani et al. 2015), P. cryptogea (Pethybridge & Lafferty 1919) and P. erthroseptica (Pethybridge 1913). These species together with P. drechsleri (Tucker 1931), P. sansomeana (Hansen et al. 2009), P. medicaginis (Hansen & Maxwell 1991) and P. tri- folii (Hansen & Maxwell 1991) clustered within clade 8a of the Phytophthora phylogeny (Yang et al. 2017). In a multi gene phylogeny of the ITS, Btub, hsp90, coxI and nadh1 gene re- gions, P. kelmanii differs from its closest sister taxon, P. pseudo- cryptogea, by 1.3 %. Morphologically, P. kelmanii is similar to other species in clade 8a, producing terminal, typically ovoid, persistent, non-papillate sporangia, and it is also a high- temperature tolerant Phytophthora species. The IDphy online resource was used for close evaluation of P. kelmanii and related species (Abad et al. 2019). Isolates of P. kelmanii are heterothallic similarly to P. pseudocryptogea, P. cryptogea and P. drechsleri, however, four of the five isolates examined were sterile and did not produce any oospores in dual cultures. In ad- dition many oospores aborted after the formation of the oospore wall. Unlike P. pseudocryptogea, P. cryptogea, P. erthroseptica and P. drechsleri, P. kelmanii produced small chlamydospores on agar. Phytophthora kelmanii frequently forms small clustered hyphal swellings in culture media, water and soil solution cul- tures which is a typical character of the species. Phytophthora kelmanii was first isolated in 1989 from Abies fraseri, Salvia officinalis and Picea abies in North Carolina, USA (Abad et al. 2002). Thereafter it has frequently been isolated from firs, herbaceous ornamentals, and even agriculturally important trees such as walnut, around the world. 498 Persoonia – Volume 46, 2021 Pleuroflammula pannonica 499Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1268 – 13 July 2021 Pleuroflammula pannonica Polhorský, Kautmanová & Szabóová, sp. nov.

Notes — Ovoid, thick-walled, rust brown basidiospores, cylin- drical cheilocystidia, eccentric stipe, indistinct but present veil and orange-brown pigment dissolving in KOH agree well with the generic concept of Pleuroflammula and distinguishes it from morphologically similar genera (Crepidotus, Phaeomarasmius, Pholiota, Simocybe) (Horak 1978, 2018). Most of the c. 20 described species are known from the USA, but several other species are only from countries in the Southern Hemisphere (Chile, Brazil, South Africa, Indonesia, Papua New Guinea, Aus- tralia and New Zealand). Presently the only known species from Europe were cosmopolitan-appearing P. ragazziana (Gierczyk & Kubiński 2019) and P. tuberculosa (Horak 1986). From Euro- pean taxa, P. pannonica superficially resembles small members of the genus Phaeomarasmius, e.g., P. rimulincola and P. siqui- eri (Salom & Esteve-Raventós 2011), but differs in KOH-soluble pigment, not encrusted cheilocystidia and smaller spores. This new species represents the smallest member of the genus next to P. minutula (pileus 2–6 mm diam), which differs in more persistent veil, broader cheilocystidia (4–7 μm) and growth on living bark of Populus (Smith & Hesler 1968). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of BRA CR33236 were P. croceosanguinea (strain TFB8631, Gen- Bank KY559341; Identities = 540/583 (92 %), 16 gaps (2%)), P. flammea (AFTOL-ID 1381, GenBank DQ494685; Identities = 507/578 (88 %), 26 gaps (4 %)) and P. praestans (PBM3461, GenBank HQ832450; Identities = 519/597 (87 %), 36 gaps (6 %)).

Notes — Russula quintanensis differs from other sequestrate species of Russula because of its angiocarpic (gasteroid) basi- diomata, loculated gleba without a columella, and its ellipsoid spores 8.5 × 6.5 µm on average (Q = 1.4) ornamented with very small warts 0.1–0.2 µm high that sometimes coalesce forming small ridges. The closest matches in public databases to the LSU and rpb2 sequences obtained come from specimens iden- tified as R. cessans, R. laricina, R. maculata, R. nauseosa and others (about 97 % similarity of LSU, 96 % similarity of rpb2). Phylogenetic analysis based on ITS, LSU and rpb2 confirms that R. quintanensis is nested within subsect. Lari cinae (see Supplementary material FP1273). Other sequestrate species have been found in this subsection before (Vidal et al. 2019), such as Russula galileensis, R. sichuanensis, R. subloculata and R. vinaceodora, but they all have pseudoangiocarpic (seco- tioid) basidiomata. Russula californica turns ocherish orange in the gleba with KOH, has subglobose spores 9–12 × 7.5–9 µm ornamented with larger warts 0.25–0.5 µm wide, and cystidia. Russula monticola has globose to subglobose spores, 9.5–12 × 10–12.5 µm, ornamented with isolated or coalescing warts, 0.5–1.1 µm high. Russula setigera has a trichoderm peridio- pellis, abundant cystidia, and globose spores 8–10(–11) µm ornamented with an incomplete reticulum. Finally, R. vidalii has also a trichoderm peridiopellis, abundant macrocystidia, and subglobose spores 9–11(–13) µm ornamented with warts 0.5–1 µm high. Russula andaluciana (Moreno-Arroyo et al. 2002) can be found in the same habitats and season, but differs from R. quintanensis because of its remarkable smell, as well as its globose to subglobose basidiospores ornamented with spines 0.3 µm high forming a reticulum. 504 Persoonia – Volume 46, 2021 Simplicillium niveum 505Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1274 – 13 July 2021 Simplicillium niveum Mongkols., Noisrip. & Luangsa-ard, sp. nov. Etymology. From the Latin ‘niveus’, referring to white mycelium of the fungus on the host. Classification — Cordycipitaceae, Hypocreales, Sordario- mycetes. Mycophylic on Ophiocordyceps camponoti-leonardi (Ophio- cordycipitaceae) attached to unidentified dicotyledonous leaves of forest plants. Mycelium white. Conidial structures consisting of erect conidiophores usually arising from prostrate myce- lium, verticillate with phialides in whorls of two to five on each branch. Conidiogenous cells phialides, gradually tapering from base to the apex, 10–20.5(–25) × 1–2 µm. Conidia hyaline, oblong-ellipsoidal or ellipsoidal, smooth, aseptate, 3–4.5(–6) × 1–2 µm, aggregated in heads at the apex of phialides. Sexual morph not observed. Culture characteristics — Colonies initiated from germina ting conidia. Conidia germinated within 24 h on potato dextrose agar (PDA). Colonies reaching 8–12 mm diam after 7 d at 25 °C. Colonies compact with white mycelium, reverse uncoloured. Conidia and reproductive structures not observed.

Notes — Species in Simplicillium have been reported oc- curring on a broad spectrum of hosts and substrates, such as insects, plants, rusts, soil, decaying wood, calcareous rock (Zare & Gams 2001, Liu & Cai 2012, Nonaka et al. 2013, Zhang et al. 2017, Chen et al. 2019). Simplicillium lanosoniveum has been reported as both an endophytic and hyperparasitic fungus (Baiswar et al. 2014, Wei et al. 2019). The gross macromor- phology of the natural samples of S. niveum closely resembles S. lanosoniveum (Wei et al. 2019) by producing white hyphae on decayed O. camponoti-leonardi (Kobmoo et al. 2012), but O. unilateralis (Wei et al. 2019) was the host reported for the latter. Both species produce phialides with aggregated co- nidia on the host surface. However, the micromorphological characters in S. niveum differ from S. lanosoniveum in having verticillate conidiophores with phialides in whorls, whereas S. lanosoniveum produces solitary phialides along its hyphae. Results of the molecular phylogenetic study strongly support and separate S. niveum from other known species. Colour illustrations. Forest in Thailand.

Notes — Starmerella includes 48 yeast species (http://www. indexfungorum.org; search date 08.04.2021) that are associ- ated with flowering plants and related insects, mainly stingless bees (Lachance 2011). Two novel Starmerella strains associ- ated with carpenter bees, CBS 5659 and CBS 6396, were isolated and deposited to the CBS yeast collection by J.P. van der Walt in 1960 and 1980, respectively. The two strains are conspecific (99 % sequence similarity in LSU: one subst. and 100 % sequence similarity in ITS nrDNA). Phylogenetic analysis using combined sequences of ITS and LSU nrDNAsequences of the novel strains and closely related yeasts belonging to the Starmerella clade placed the two strains within the subclade of S. tilneyi CBS 8794T and S. vaccinii CBS 7318T as a sister branch. Pairwise sequence analysis from a multiple alignment showed that the new strains have 92.3 % sequence similar- ity (626 identical nt., 49 subst., 26 gaps) with S. tilneyi and 91.3 % sequence similarity (619 identical nt., 50 subst., 25 gaps) with S. vaccinii. Comparison of the physiological pro- perties confirmed the distinction of the new strains from the closely related yeast species S. tilneyi and S. vaccinii. The novel strains can be distinguished from S. tilneyi based on nine physio logical characteristics. The strains can assimilate D-ribose, α,α-trehalose, ribitol and cannot assimilate inulin, xylitol and N-acetyl-glucosamine. Unlike S. tilneyi the strains are able to assimilate nitrate and nitrite and are not able to grow on medium without vitamins. Ten physiological characteristics discriminate the new strains from S. vaccinii. The strains can assimilate D-ribose, α,α-trehalose and ribitol. The strains are not able to assimilate sucrose, cellobiose, salicin, arbutin, raffinose and xylitol. Unlike S. vaccinii, the novel strains are not able to grow at 37 °C. 508 Persoonia – Volume 46, 2021 Suillus praetermissus 509Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1276 – 13 July 2021 Suillus praetermissus Zvyagina & Svetash., sp. nov.

The GenBank accession numbers are indicated after species names. Novel species is indicated in a bold font in the green box. Support values are indicated on the branches (posterior probabilities). Scale bar = 0.4 expected substitutions per site. The alignment and tree were deposited in TreeBASE (study S27683). Notes — The olive yellow cap and ash grey dots on the stipe surface, as well as larger spores, distinguish S. praetermissus from the closest species of the Suillus acidus group. According to phylogenetic analysis, the nearest species is S. subaluta- ceus, p-distance is 1.8 %, 12 nucleotide substitutions per 666 alignment positions of ITS1-5.8S-ITS2. According to a micro- scopic examination of the type specimen of S. subalutaceus (MICH 50221) carried out by E. Zvyagina, its spores are much shorter with the same width. The cap surface of S. subaluta- ceus is ‘pinkish-buff ’ (Smith & Thiers 1964). Suillus subaluta- ceus forms mycorrhiza with two-needle pines (Nguyen et al. 2016), while the new taxon S. praetermissus is associated with five-needle pines. In our study all examined specimens were collected under Pinus sibirica. However, for specimens and my- corrhizal samples from Japan, of which sequences were used in the phylogenetic tree, an association with P. corayensis and P. pumila was also noted. Suillus subalutaceus is an American species, while S. praetermissus has an Asian distribution. 510 Persoonia – Volume 46, 2021 Tetraploa endophytica 511Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1277 – 13 July 2021 Tetraploa endophytica G.

Notes — Tetraploa species are characterised by distinct, brown, smooth or verrucose conidia composed of four columns of 2–6 cells, each one terminating in a septate, setiform appen- dage that tend to diverge apically from one another and are borne on monoblastic conidiogenous cells (Ellis 1971, Whitton et al. 2012). They are linked to massarina-like sexual morphs and are currently placed in their own pleosporalean family, Tetraplosphaeriaceae, along with other genera having appen- diculate, tetraploa-like asexual morphs (Tanaka et al. 2009). Some members of Tetraploa are ubiquitous and they mostly occur on leaves or stems of monocotyledons such as bamboo, but also on various dicotyledons. However, there are very few reports of them as endophytes and only the widespread T. aristata has been isolated from Opuntia ficus-indica (Cacta- ceae) (Rashmi et al. 2019).

Our strain did not sporulate in any of the different culture media used including MEA, PDA, MCA or Water Agar supplemented with wooden toothpicks. Phylogenetically, it clustered with a Tetraploa sp. strain P1501, represented only by an ITS sequence (GenBank KY987533.1), which is also a root endophyte isolated from Polygonum chinense (Polygonaceae) in China (Liu et al. 2017), and probably conspecific. Another root endophyte, Tetraploa sp. strain M1403, isolated from Stellaria media (Caryophyllaceae) also during the study of Liu et al. (2017), grouped sister to our strain but without support. It occurs in a strongly supported group with the ex-type strain of T. sasicola and an isolate of this species obtained from a root of wild Vaccinium sp., suggesting that some Tetraploa taxa are possibly well adapted to the root endophytic lifestyle. Based on a megablast search of NCBIs GenBank nucleotide database, the closest hits using the ITS sequence of Tetraploa endophytica (CBS 147114) are Tetraploa sp. (strain P1501 as Tetraplosphaeria sp., GenBank KY987533.1; Identities = 511/ 512 (99 %), no gaps), Tetraploa sp.

The alignments included 552 bp and 3 423 bp, respectively, and were performed with MAFFT v. 7 (Katoh et al. 2019). The General Time Reversible model with a gamma distribution and invariant sites was used as the best nucleotide substitution model. The phylogenetic analysis was conducted in MEGA v. 6 (Tamura et al. 2013). The novel species is indicated in bold font. GenBank MK050289; Identities = 372/430 (87 %), 17 gaps (3 %)). The closest hit using the LSU sequence is T. helanensis (CGMCC 2.4450T, GenBank MK050287; Identities = 495/513 (96 %), two gaps (0 %)), using SSU it is T. korlaensis (CGMCC 2.3835T, GenBank MK050286; Identities = 1 656/1 675 (99 %), one gap (0 %)), using tef1 it is T. rudbeckiae (CGMCC 2.5840T, GenBank MT268695; Identities = 437/480 (91 %), 11 gaps (2 %)) and using rpb1 the number of nucleotide substitutions was considerable – without hits with Teunia and Kwoniella. In agreement with results of the recent analysis of the genus Teunia (Wang et al. 2020), the phylogenetic position of the new species is demonstrated using the LSU rDNA phylogeny. Results of the analysis suggest that strains KBP Y-6495 and KBP Y-6428 belong to a new species, which occupies a basal position in the Teunia clade. Because the new species was distantly related to other species of the genus, a multi-locus phylogenetic analysis of concatenated sequences of ribosomal genes (SSU, ITS and LSU) and two protein-coding regions (rpb1 and tef1) was performed. The Teunia clade and the strain KBP Y-6495 received strong support in the analysis. Teunia lichenophila sp. nov. is distinguished from the closest (accor ding to the multi-locus phylogenetic analysis) species T. cuniculi by more than 10 physiological tests. 514 Persoonia – Volume 46, 2021 Tubaria vulcanica 515Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1279 – 13 July 2021 Tubaria vulcanica G.

S1.04, 33006 Oviedo, Spain; e-mail: pablo.alvarado@gmail.com Notes — The genus Tubaria is actually included in the family Tubariaceae, along with Flammulaster, Phaeomarasmius and Phaeomyces (Vizzini 2008, Vizzini et al. 2019). Tubaria vul- canica is characterised by its smooth, amygdaliform to ellipsoid spores, and lageniform to tibiiform cheilocystidia. Its basidiomes were found growing directly on volcanic lapilli material used for gardening or pavement in the Canary Islands. Following Bon (1992), T. vulcanica could be included in sect. Pallidosporae because of its lamellae of pallid colour when young, and thin walled, amygdaliform and not pigmented spores. Its LSU rDNA sequence is close to one identified as Tubaria albostipitata (GenBank EF051051, 98.24 % similar), but the new species has a differently coloured stipe, larger spores and cheilocystidia, and pileipellis with much broader elements. ITS rDNA is 97.55 % similar to one sequence obtained from forest soil litter in Ar- kansas, USA (GenBank MK234224) and rpb2 is 84 % similar to several undetermined sequences of Tubaria sp. (GenBank MH618217, HQ839738, MH618216). 516 Persoonia – Volume 46, 2021 Tuber zambonelliae 517Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1280 – 13 July 2021 Tuber zambonelliae Ant. Rodr. & Morte, sp. nov. Etymology. Named after Alessandra Zambonelli, from the University of Bologna, mycologist and specialist in hypogeous fungi and mycorrhizae, for her outstanding contribution to the knowledge of Tuber spp. Classification — Tuberaceae, Pezizales, Pezizomycetes. Ascomata hypogeous, 0.5–2 cm diam, subglobose, pale brown, smooth, minutely pruinose. Peridium 100–200(–300) μm thick, composed of hyaline, agglutinated, interwoven hyphae (intricate texture). Gleba firm, solid, whitish at first, becoming pale to dark brown at maturity, marbled with numerous, branching, white and dark veins. Odour pleasant. Asci inamyloid, 60–70 × 40–50 μm excluding stalk, pyriform to clavate or subglobose, with a long or short stalk arising from a crozier, 10–40 μm long, walls 1–2 μm thick, 1–4(–5)-spored. Ascospores 22–45 × 16–26 μm, Q = 1.4–1.9, excluding ornamentation, at first hyaline, yellow- ish brown at maturity, ellipsoidal to ovoid, orna mented with short spines, 1–2 µm long, often connected by lower ridges, making the ornamentation an irregular and incomplete spiny reticulum. Ecology & Distribution — Tuber zambonelliae grows in Me- diterranean Quercus ilex subsp. ballota forests, in limestone mountains of the south of the Iberian Peninsula, 1 000–1 300 m in altitude.

Species hypotheses for undescribed species (Tuber sp. followed by numbers) follow the conventions of Bonito et al. (2010). Notes — Tuber zambonelliae is a pale brown truffle that clusters in the rufum clade, and is characterised by its smooth peridium, brown gleba marbled with white and dark veins and spiny-reticulate spores. Tuber zambonelliae resembles Tuber nitidum, but in addition to genetic differences, T. nitidum differs by having a basal cavity, peridium with cellular structure in the outermost layer and smaller spores with separate and shorter spines (Ceruti et al. 2003). Tuber requienii also resembles Tuber zambonelliae but it has a papillose peridium and lacking dark veins (Tulasne & Tulasne 1851). HQ204754 Tuber sp.

Notes — BLAST analyses with the ITS and LSU region of Xero chrysium bohemicum showed greatest similarity with isolates of X. xerophilum (~94.8 % / ~99.4 %), X. dermatiti- dis (~93.8 % / ~98.4 %) and Xeromyces bisporus (~89.6 % / ~98.2 %). Xerochrysium bohemicum is morphologically similar to X. der- matitidis and X. xerophilum, but grows more rapidly. Xerochry- sium bohemicum and X. xerophilum differ from X. dermatitidis by almost complete differentiation of vegetative hyphae into intercalary arthroconidia (Pitt et al. 2013). 520 Persoonia – Volume 46, 2021 Fusarium juglandicola 521Fungal Planet description sheets © 2021 Naturalis Biodiversity Center & Westerdijk Fungal Biodiversity Institute Fungal Planet 1282 – 13 July 2021 Fusarium juglandicola L.

Notes — Fusarium juglandicola was repeatedly isolated from walnut (fruits or flower buds), and based on tef1 sequences, initially considered closely related to F. lateritium. Later, these isolates were considered much closer to F. salinense. Following this reclassification, a re-examination of some strains (UBOCC collection) initially classified as closely related to F. lateritium, Colour illustrations.

Fusarium juglandicola nested within the F. citricola species complex. Similar to F. celtidicola, F. citricola and F. salin- ense, this slow-growing species only forms monophialidic conidiogenous cells in culture, and produces up to 5-septate sporodochial conidia (Sandoval-Denis et al. 2018, Shang et al. 2018). However, F. juglandicola is easily distinguished from F. celtidicola, F. citricola and F. salinense by the lack of aerial microconidia and absence of chlamydospore formation. Ad- ditionally, F. juglandicola does not produce red pigments when incubated under continuous white light as has been reported for the other three species in this complex (Sandoval-Denis et al. 2018, Shang et al. 2018). Based on a megablast search of NCBIs GenBank nucleotide database, the closest hit using the ITS sequence had the high- est similarity to Fusarium lateritium (strain BBA 65248, GenBank AF310980.1; Identities = 571/572 (99 %), no gaps), Fusarium tricinctum (strain 05009, GenBank MG274297.1; Identities = 570/572 (99 %), no gaps) and Fusarium citricola (strain CPC 27813, GenBank LT746246.1; Identities = 570/572 (99 %), no gaps).

Notes — Fusarium aconidiale is phylogenetically closely related to F. celtidicola and F. juglandicola in the F. citricola species complex (FCCSC; Sandoval-Denis et al. 2018, Shang et al. 2018). Similar to F. juglandicola, this species does not produce red pigment under continuous white light nor any chlamydospores or aerial microconidia, distinguishing it from other members of the FSSCS. However, F. aconidiale produces predominantly 3-septate sporodochial conidia and much less frequently 4- and 5-septate sporodochial conidia compared to F. juglandicola. Colour illustrations.

The robustness of the analysis was evaluated by boot- strap support (BS) with the number of bootstrap replicates automatically determined by the software. The combined sequence dataset included 19 ingroup taxa with Fusarium heterosporum (CBS 391.68) as outgroup. The dataset consisted of 4 177 characters including gaps. Additionally, MrBayes v. 3.2.1 (Ronquist & Huelsenbeck 2003) was used for BI to generate phyloge- netic trees under optimal criteria for each locus. A Markov Chain Monte Carlo (MCMC) algorithm of four chains was initiated in parallel from a random tree topology with the heating parameter set at 0.3. The MCMC analysis lasted until the average standard deviation of split frequencies was below 0.01 with trees saved every 1 000 generations. The first 25 % of saved trees were dis- carded as the ‘burn-in’ phase and posterior probabilities (PP) were determined from the remaining trees. Support values (BS & PP values) are indicated at the branches. The scale bar indicates 0.04 expected changes per site.
