Three new species, Pachykytospora nepalensis T. Hatt., Phellinus subsanfordii T. Hatt., Trichaptum montanum T. Hatt. are described. Pachykytospora nepalensis is characterized by the long tubes (up to IOmrn deep), white and large (2- 3/mrn) pores, and tuberculate basidiospores measured 8.5- 11. 5 X4.5- 6.5 f1.m . Phellinus subsanfordii is characterized by the duplex context with a thin crust, scattered hyphoid setae, and subglobose and almost colorless basidiospores. T montanum is characterized by the duplex context with white and fibrous tomentum, tubular hymenophore with regular pores, and cy lindrical basidiospores measured 5.2- 6.5 X 1.2- 2.0 p.m .
