New records to the fungal biodiversity list of the Yuganskiy Nature Reserve (Western Siberia)

We present an annotated list of species of fungi which were found in the southern part of the Surgutskiy district (Western Siberia). Specimens were collected in 1996-2015 within the territory bounded by the rivers Bolshoy Yugan, Maliy Yugan and Antl’tur’yakh. The central part of this territory is the protected area of the Yuganskiy Nature Reserve (648656 ga). Vegetation of this territory consists of primary mixed dark taiga and secondary pine, aspen and birch forests. Various combinations of Picea obovata, Abies sibirica, Pinus sibirica, Pinus silvestris, Populus tremula, Betula pendula form a tree layer. Feather mosses, low shrubs and forb cover the ground. One third of the area is bogged. We provide collection records for 304 specimens. Each record provides information about location of the specimen, community types, substrate, abundance and collections number. The English version of the list is available as an .xls file in the Electonic Appendix. The collection is stored in the Yuganskiy Nature Reserve (268 specimens) and LE (36 specimens). The list contains 216 species from the five groups (heterobasidiomycetous, polyporoid, agaricoid, clavarioid basidiomycetes, and discomycetes) and 44 families (Agaricaceae (1), Auriscalpiaceae (1), Bankeraceae (5), Boletaceae (1), Cortinariaceae (4), Cyphellaceae (1), Discinaceae (1), Elaphomycetaceae (1), Entolomataceae (5), Gomphidiaceae (4), Helotiaceae (1), Helvellaceae (3), Hyaloscyphaceae (1), Hydnangiaceae (1), Hygrophoraceae (17), Hymenogastraceae (6), Hypocreaceae (1), Inocybaceae (7), Lachnaceae (1), Lyophyllaceae (3), Marasmiaceae (2), Mycenaceae (14), Omphalotaceae (9), Ophiocordycipitaceae (1), Pezizaceae (2), Physalacriaceae (2), Pleurotaceae (1), Pluteaceae (3), Polyporaceae (2), Psathyrellaceae (4), Pyronemataceae (10), Repetobasidiaceae (2), Rhizinaceae(1), Russulaceae (41), Sarcoscyphaceae (1), Sarcosomataceae (2), Sclerotiniaceae (1), Strophariaceae (14), Suillaceae (4), Thelephoraceae (1), Tremellaceae (1), Tricholomataceae (26), Tubariaceae (2), Incertae sedis (5)). 79 taxa are new records for Khanty-Mansiysk Autonomous okrug – Ugra.
