Polypore fungi species (Agaricomycetes, Basidiomycota), new to the Kaluga Region, Russia

Abstract

Eight species of aphyllophoroid fungi with poroid hymenophore were revealed for the first time for the Kaluga Region (European part of Russia) as a result of a mycological survey of forest ecosystems carried out by the author in August 2022 in the southern area of the Kaluzhskie Zaseki State Nature Reserve. The species Poriella subacida is listed for the first time in the Central Russian Upland. Detailed information on recorded wood substrates and habitats, geographical coordinates of findings, and numbers of herbarium specimens deposited in the Mycological Herbarium of the Komarov Botanical Institute of the RAS (LE) are given for each species. The features of ecology and distribution of new to the Kaluga Region fungal species in the adjacent regions and in Russia as a whole are briefly discussed.
