Abstract: In this paper distributional patterns and species composition of corticioid fungi (Corticiaceae s. l.) in forest ecosystems of Byarezinski Reserve were studied in permanent plots. The number of species per plot varies from 6 in oligotrophic bogs (Pino- Ledetum) to 47 in broadleaf-spruce forests (Querco-Piceetum). The cluster analysis of species lists revealed two main groups of biocoenoses with specific assemblages of fungi: southern taiga non-swamp coniferous forest and swamp forests dominated by alder and birch. The major factors determining biocoenotic preferences and species richness of fungi are number of tree and shrub species in community, coniferous/ deciduous hosts proportion, and soil humidity.
