Abstract: A new species Junghuhnia vitellina Spirin is described, growing on Betula mandshurica in Russian Far East. Cinereomyces lenis (P. Karst.) Spirin, comb. nova is a so-called kelo fungus; its closest relative C. vulgaris (Fr.) Spirin, comb. nova has relatively wide set of hosts. The latter is new to Russia. Eleven species of Skeletocutis are discussed, and some data on their ecology are treated. S. chrysella Niemelä, S. subincarnata (Peck) Jean Keller and S. stellae (Pilát) Jean Keller are rare taiga species, growing on large spruce or pine trunks at late stages of wood-decomposition. S. biguttulata (Romell) Niemelä and S. brevispora Niemelä are locally common and found in both southern and northern parts of the study area. S. carneogrisea David and S. kuehneri David grow in association with Trichaptum species in virgin as well as managed coniferous forests. S. albocremea David is very rare; it was collected only once in old pine forest. S. kuehneri and S. papyracea David are new to Belarus.
