Revision of the Genus Entoloma s.l. (Entolomataceae, Agaricales, Basidiomycota) in the Komi Republic (North-East of the European Part of Russia)

The article presents the results of the revision of the genus Entoloma s.l. in the Komi Republic, based on morphological and molecular genetic approaches in accordance with modern data on the genus taxonomy and systematics. An annotated list of 50 species has been compiled, including 25 ones provided for the first time for the region, three of which (Entoloma frigidum, E. fuligineccinereum, E. mutabilipes) are registered for the first time for Russia, and E. pallidocarpum is new species to Europe. The presence of E. mirum in Russia is confirmed for the first time based on the study of basidiomata. The species identification was verified using molecular methods. For most of the studied species, nucleotide sequences of ITS1–5.8S–ITS2 marker have been obtained and deposited in the GenBank. The distribution of Entoloma species by landscape areas and main habitat types is considered. The largest number of species (29) is recorded in the lowland landscape area. The highest species diversity was observed in mixed (25) and spruce (18) forests.
