Notes on Medicinal Polypore Species from the Genus _Daedaleopsis_ (Agaricomycetes) Distributed in the Asian Part of Russia

We present a study on the medicinal value, taxonomy, and ecology of the polypore mushrooms Daedaleopsis confragosa and D. tricolor isolated from the Asian part of Russia (the Urals, Siberia, and the Far East). The phylogenetic analysis of recombinant DNA internal transcribed spacer sequences data has shown that D. confragosa and D. tricolor do not differ taxonomically and should be considered as one species. However, because D. confragosa and D. tricolor differ significantly in their ecological characteristics, they may be considered as two morpho-ecological varieties: D. confragosa var. confragosa and D. confragosa var. tricolor (both nomen provisiorum).
