This platform provides aggregated reports derived from a comprehensive database on the biodiversity of basidiomycete macrofungi in Russia, compiling distributional data from available scientific literature. The primary objective of this resource is to offer open access to structured information—ranging from regional species checklists to the geographical distribution of specific taxa. It is intended to serve as a useful resource for floristic, biogeographical, and taxonomic research. While species names have been standardized to reflect currently accepted taxonomy, the project does not critically re-evaluate the original biological identifications; occurrence records are accepted as published, and all underlying data are explicitly linked to their source publications.
