Three new species of Hymenochaete from Russian Far East are described based on morphological and ITS rDNA data. Hymenochaete adhaerens sp. nov. is a resupinate species closely related to H. macrospora, from which it differs in having longer basidiospores and setae. The basidiocarps of H. cupulata sp. nov. are effused-reflexed, resembling those of the European H. ulmicola, from which it differs in having setae inflated at the basal part and shorter basidiospores. Both H. adhaerens and H. cupulata inhabit bark of living elm trees (Ulmus spp.). H. manshurica sp. nov. is resupinate and morphologically similar to the North American H. corticolor, from which it differs in having narrower setae and basidiospores; it has been collected from bark of living Tilia manshurica.
