- Аннотация: The study of fungal diversity of peatlands started over a century ago with a microbiological approach (for a detailed history of research of fungi in peatlands, see Thormann 2006, Rydin et al. 2006 and Artz 2013. Microfungal communities of peat layer were first studied using in vitro culture techniques: fungi were discovered at all depths, but in the lower peat layers, they were considered dormant. The composition and structure of microfungal communities depend on micro-element composition, decomposition state and aerobic conditions of the peat horizons (Thormann 2006, Chernov 2018). The microbiological approach, however, is biased towards species of microfungi easily cultivated in vitro. With an integral approach, peatlands became a subject of interest to mycologists working by direct observation of fruit-bodies of macromycetes. Studies of different types of peatlands were carried out in a variety of paludified regions globally; the following works are noteworthy: Favre (1948) Jura mountain range, France; Einhellinger (1976), Einhellinger (1977) Upper Bavaria, Germany; Lange and Lange (1982) Maglemose, northern Denmark; Stasinska (2011) Pomeranian peatlands, Poland; Ohenoja (1974) and Salonen and Saari (1990) Finland; Kalamees (1982), Kalamees and Raitviir (1982) Estonia; Kotlaba (1953), Kotlabam and Kubicka (1960), Vašutová et al. (2021), Vašutová et al. (2023) in Czechia; Chastukhin (1965) north-western Russia. With the recent development of environmental DNA methods of sampling, all methods complement each other, helping to reveal the diversity and ecological role of fungi in peatlands. A number of published works employed the environmental DNA approach in peatlands: Jackson et al. 2008, Elliott et al. 2015, Garcés-Pastor et al. 2019, Kim et al. 2021, Vašutová et al. 2021; however, the results were rarely verified by cultures or direct observation of fruit-bodies.In this study, we aimed to describe the diversity, community structure and dynamics of macromycetes of peatlands in West Siberia by direct observation and complement it by a molecular approach (barcoding of accumulated collections). In contrast to the existing research, we used permanent plots with regular visits throughout the growing (snow-free) season from May till October and have been monitoring the plots for nine years, which is, to our knowledge, the longest observation series on the community of macromycetes in peatlands. Long-term plot-based monitoring is necessary to reveal the fullest possible diversity of macromycetes, as shown by many authors (O'Dell et al. 2004). There had been no published in-depth studies in regard to macromycetes of peatlands before the beginning of this project in Western Siberia; the study complements several research initiatives on peatland fungal diversity conducted country-wide in Russia. The plot-based description of the community by the direct observation method will be validated or used for validation for future metabarcoding analyses in the same location.This publication aims: to summarise the results of nine years of plot-based monitoring of the community fruiting dynamics; to describe the quantitative structure of the community, to reveal dominant and rare species and gain insight into its potential protection status; to revise the species diversity of macromycetes by barcoding the voucher collection.
