Abstract


Rhodocybe tugrulii sp. nov. is described based on both morphological and molecular data (analysis of nrITS and nrLSU sequences) from Zigana Mountain, Trabzon, Turkey and Lääne County, Estonia. It is distinguished by the grey to beige or slightly reddish brown basidiomata, a small, convex to hemispheric, cracked pileus surface, decurrent lamellae; a pruinose and cylindrical stipe; 2- or 4- spored basidia; and hyaline, somewhat angular to broadly ellipsoid, sometimes obscurely bumpy, on average 5.9 × 4.9 μm inamyloid basidiospores. Colour photographs of fresh basidiomata and of the main micromorphological features and a comparison with the allied species are included. Based on molecular evidence, Clitocella obscura comb. nov. is proposed.
