Synopsis of the macrofungi (<i>Basidiomycota</i>) on wood of fruit trees in the Central Black Earth Region of Russia

Aim . To summarise and analyse data on the species diversity, distribution and substrate spectra of wood-inhabiting basidial macromycetes growing on fruit trees in the Belgorod, Voronezh, Kursk, Lipetsk, Oryol and Tambov Regions. Material and Methods . The work involved a critical examination of literature sources, LE, OHHI, and VU herbaria. We undertook field researches in 2019-2020, identified specimens collected based on light microscopy techniques and isolated the basidial fungi in a pure culture. Results . Data on 97 species of basidial macrofungi from 68 genera associated with Malus, Pyrus and Prunus wood in the Central Black Earth Region are summarised. Antrodia serpens and Ceriporia torpida are newly known to Russia. 65 new dikaryot-ic strains for 22 species of Agaricomycetes have been introduced into the LE-BIN. A total of 65 species are associated with Malus, 34 species with Pyrus and 29 species with Prunus . Five species ( Lyomyces crustosus, Stereum hirsutum, Trametes hirsuta, T. ochracea and T. versicolor ) grow on all three genera of host. These species specialise in fruit trees include Sarcodontia crocea and Phellinus pomaceus . Conclusion . Pathogenic activity has been clearly observed for 32 species of fungi found on trunks and branches of living trees, causing necrosis and trunk rot. Furthermore, it is recommended that regular phytopathological monitoring of orchards should be carried out, taking the group of xylotrophic fungi into account.
