Polypores from eastern Xizang (Tibet), western China

A field expedition to study wood-inhabiting fungi in eastern Xizang Autonomous Region (Tibet), western China, was made in summer of 2004, and based on materials collected during the expedition and some herbarium specimens 154 poroid aphyllophoraceous fungi were identified. This paper gives a checklist of our results, and most of the species are here reported for the first time from Xizang. Substrates and collecting data of each species are supplied in the checklist. Ceriporiopsis egula C.J. Yu & Y.C. Dai, Heterobasidion linzhiense Y.C. Dai & Korhonen and Polyporus subvarius C.J. Yu & Y.C. Dai are new to science, and illustrated in line drawings. Species diversity of polypores in eastern Xizang is very high. The major component of the eastern Xizang polypore flora is widely distributed circumpolar, temperate and boreal species.
