Species diversity of the biota of basidiomycetes of the Volgograd region in the autumn period

The biota of basidiomycetes from the Volgograd region has been studied severely limitedly and irregularly. The collection of basidiomycetes was carried out from 2010 to 2023 on the territory of Volgograd and its surroundings: Kirovsky, Sovetsky, Voroshilovsky, and Central districts of Volgograd, Natural Park “Volga-Akhtuba Floodplain,” Grigorova Bend, and Chapurnikovskaya Bend. There were collected 506 specimens of basidiomycetes belonging to 65 genera, 34 families, and 10 orders. The leading orders in the number of species are Polyporales (38) and Agaricales (23). The multi-species family is Hymenochaetaceae (13). The largest number of basidiomycetes is noted for the genus Phanerochaete (5). The leading environmental group is saprotrophs on dead and dry wood (61%). The greatest number of wood-destroying fungi was recorded on Quercus robur L., Populus alba L., P. nigra L., and Fraxinus lanceolata Borkh. due to their predominance in the study area.
