Synopsis of the macrofungi (Basidiomycota) 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.

Peculiarities of successional changes of xylotrophic basidiomycetes during decomposition of dominant tree species of forest formations of the Pitsunda-Myussera Reserve of the Republic of Abkhazia

The article is about the biodiversity of xylotrophic fungi of oak and hornbeam forests of Abkhazia and related destructive processes of the main forest-forming species (oak and hornbeam). The species composition of fungi subjected to phytopathogenic and saprotrophic methods of decomposition was determined. The species composition of mycobiota, causing wood xylolysis practically up to the last stages of decomposition, has been determined. Key words: biodiversity, xylotrophic fungi, succession, Republic of Abkhazia.

Green potential ofPleurotusspp. in biotechnology

BackgroundThe genusPleurotusis most exploitable xylotrophic fungi, with valuable biotechnological, medical, and nutritional properties. The relevant features of the representatives of this genus to provide attractive low-cost industrial tools have been reported in numerous studies to resolve the pressure of ecological issues. Additionally, a number ofPleurotusspecies are highly adaptive, do not require any special conditions for growth, and possess specific resistance to contaminating diseases and pests. The unique properties ofPleurotusspecies widely used in many environmental technologies, such as organic solid waste recycling, chemical pollutant degradation, and bioethanol production.MethodologyThe literature study encompasses peer-reviewed journals identified by systematic searches of electronic databases such as Google Scholar, NCBI, Springer, ResearchGate, ScienceDirect, and ISI Web of Knowledge. The search scheme was divided into several steps, as described below.ResultsIn this review, we describe studies examining the biotechnological feasibility ofPleurotusspp. to elucidate the importance of this genus for use in green technology. Here, we review areas of application of the genusPleurotusas a prospective biotechnological tool.ConclusionThe incomplete description of some fungal biochemical pathways emphasises the future research goals for this fungal culture.

Communities of woody vegetation and wood destroying fungi in natural and semi-natural forests of kyiv city, Ukraine

Selected forestry parameters were investigated in the system of trees and wood-destroying fungi in the natural forests of the Kyiv city on a gradient of recreational transformation. We investigated the vitality, age compositions, and health condition of woody plants (11 species), and species, systematic, trophic and spatial compositions of xylotrophic fungi (51 species, 224 findings of xylotrophs representing 34 genera, 20 families, 7 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that communities of woody vegetation and xylotrophic fungi in forests depend on the degree of recreational transformation of the environment. Vitality, age compositions and health condition of trees altered species composition of xylotrophs.
