The rare gilled fungus Mycena clavata is reported from the Czech Republic for the first time. It was found on large fallen trunks of Picea abies in Boubínský prales virgin forest, the best preserved montane old-growth forest in the country. The basidiomata occurred in the lower half of the trunks, either on their upper or lateral sides, on bark covered by mosses, on bare bark, or directly on wood covered by mosses, in wet times of the year. Descriptions and photographs of macro- and microcharacters are provided and data on the distribution and ecology of M. clavata are summarised. The species was sequenced for the first time. ITS-LSU rDNA sequences confirmed the species’ distinct position and showed that M. clavata belongs to a moderately supported clade consisting of various Mycena and Hemimycena species, some of them recently transferred to the vaguely delimited genus Phloeomana.
