Asian Poria subtrametea Pil. is redescribed on the basis of new material from the Soviet Far East and its new combination in the genus Pachykytospora Kotl. et Pouz. is proposed. The very rare Pachykytospora subtrametea (Pil.) Kotl. et Pouz. is an independent species differing from the uncommon P. tuberculosa (Fr.) Kotl. et Pouz. not only in macro- and microscopical characters but also in different host and distribution pattern. An amended description of the genus Pachykytospora Kotl. et Pouz. and a key to the determination of the four known species of that genus is added. Of these, only P. tuberculosa (Fr) Kotl. et Pouz. occurs in Europe.
