Abstract
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 withMalus, PyrusandPrunuswood in the Central Black Earth Region are summarised.Antrodia serpensandCeriporia torpidaare 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 withPyrusand 29 species withPrunus. Five species (Lyomyces crustosus, Stereum hirsutum, Trametes hirsuta, T. ochraceaandT. versicolor) grow on all three genera of host. These species specialise in fruit trees includeSarcodontia croceaandPhellinus 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.
Highlights
Wood‐decaying basidial fungi are crucial components in forest ecosystems
An annotated list of basidial macrofungi species that develop on the wood of fruit trees in the Central Black Earth Region (CBER) is pre‐ sented below
In the CBER this species occurs on Acer negundo, Alnus glutinosa, Betula pendula, Populus tremula, Quercus robur, Salix sp. and Tilia cordata
Summary
Wood‐decaying basidial fungi are crucial components in forest ecosystems. These organisms play an im‐ portant role in agricultural lands, as they induce necrosis and rotten plant diseases that lead to weakening, wither‐ ing, suppression of flowering or death of trees. Russian phytopathological studies on agricultural plants generally focus on diseases caused by micromy‐ cetes [2; 3], while among polypores which cause trunk rot only common or dangerous species are mentioned [4,5,6]. The species of basidiomycete macrofungi that develop on fruit trees are often listed in more general studies [13; 14]
