A critical catalogue of Exobasidiales (Exobasidiomycetes, Basidiomycota) of north-temperate Eurasia

Abstract
The present paper is devoted to expand the understanding of the geography of the Exobasidiales order over areas of cold and northern part of the temperate belt of northern Eurasia (Russia) on the basis of the herbarium collection of the Botanical Institute of the Russian Academy of Sciences (LE). In total, in the cold and northern part of the temperate belt of northern Eurasia (Russia), we noted 27 species belonging to the genera Arcticomyces (1 species), Exobasidium (25 species), and Graphiola (1 species). All 380 LE specimens included into the present catalogue were morphologically investigated by us. It should be noted that Graphiola phoenicis dosn't occur in natural habitats of the temperate zone and is included by us as an additional material due to the fact, that it is often found on artificially planted palms in greenhouses and indoor areas. An exhaustive original description is given for each species. All the herbarium documentation is given for each species and the most of species are illustrated.
