Daedaleopsis Genus in Siberia and the Far East of Russia

The current article discusses the findings of the study of biodiversity, distribution, and ecology of Daedaleopsis species in the Siberia and Russian Far East are presented. In this part of Eurasia, the genus Daedaleopsis is represented by 3 species, D. confragosa, D. tricolor and D. septentrionalis. They are distributed in all regions of Siberia and the Russian Far East (the most common are D. confragosa and D. tricolor) and contribute to the decomposition of woody debris of several deciduous (Acer, Alnus, Betula, Carpinus, Chosenia, Crataegus Quercus, Padus, Populus, Salix, Sorbus, Tilia) and rarely coniferous (Abies) trees. Each species has its own pattern of geographical and substrate distribution. D. confragosa is mainly confined to the Salix and Alnus debris in the near- water habitats and has an azonal distribution, whereas D. tricolor is mostly abundant in southern regions where it mainly occurs on Betula and less frequently on Alnus, Padus, and Salix. Species D. septentrionalis is a geographic antipode of the D. tricolor – common in the northern regions and part of the forest zone, mainly found on woody debris of Betula, rarerly Alnus and Salix. The geographical and substrate distribution patterns of the Daedaleopsis species in the Siberia and Russian Far East are close to those in the European subcontinent. The database was uploaded to the Global Biodiversity Information Facility (GBIF) (Ural Federal University named after the first President of Russia B.N. Yeltsin publisher) on September 17th, 2020 to provide open access to data.
