Type studies in Russula 1: on two species described by Kühner.

Abstract

<p>Based on a detailed study of holotypes, emended descriptions of two somewhat problematic species are given. Recent material of those taxa is also presented with colour photographs. <em>Russula nuoljae</em> and <em>R. purpureofusca</em> were both described by Kühner based on one or two fruitbodies collected from Scandinavian fjelds. <em>R. cupreola</em> is shown to be synonymous with <em>R. purpureofusca</em>.<br /></p>
