[email protected] Holec, J. (2005): The genus Gymnopilus (Fungi, Agaricales) in the Czech Republic with respect to collections from other Eu- ropean countries. – Acta Mus. Nat. Pragae, Ser. B, Hist. Nat., 61 (1–2): 1–52. Praha. ISSN 0036-5343. The genus Gymnopilus (Fungi, Agaricales, Cortinariaceae) was monographically studied. The study is based on a thorough observation of macro- and microcharacters using numerous personal and herbarium collections from the Czech Republic. Se- lected collections from Austria, Bulgaria, Croatia, Finland, Germany, Italy, Poland, Romania, Russia, Slovakia, Sweden, and Ukraine were also used for a better understanding of the species concept. In each species, macro- and microcharacters, fruc- tification period, substrates, relation to vegetation and altitude, and distribution are evaluated in detail. Taxonomic remarks on all species are added and contemporary literature on Gymnopilus is summarised. A key for the identification of species gro- wing in the Czech Republic is provided. The following species were recognised in this area: Gymnopilus spectabilis (taxon with robust fruitbodies), G. bellulus, G. josserandii, G. flavus, G. fulgens, G. decipiens, G. penetrans (= G. hybridus), G. sa- pineus and G. picreus. The following names commonly used in contemporary literature are either not recognised in the Czech Republic or considered doubtful or hardly interpretable taxa: Gymnopilus stabilis, G.
