Hymenochaete rhododendricola and H. quercicola spp. nov. (Basidiomycota, Hymenochaetales) from Tibet, southwestern China.

Hymenochaete rhododendricola sp. nov. and Hymenochaete quercicola sp. nov. are described from Xizang Autonomous Region (Tibet), southwestern China. Hymenochaete rhododendricola is distinct in the genus by its large and heavily enmeshed setae, and growing on dead branches of Rhododendron. Hymenochaete quercicola differs from other species by its smooth or tuberculate hymenophore, presence of a cortex, relatively large and oblong-ellipsoid basidiospores, and living on dead branches of Quercus.
