fi eld trip to Mt. Fuji in Japan was made in November
2007, and some wood-decaying fungi were investigated. A
polypore, Haploporus subtrameteus (Pilát) Y.C. Dai &
Niemelä, was found on a dead tree of Padus grayana in an
angiosperm forest near Mt. Fuji. Because the fungus has not
been recorded in Japan (Núñez and Ryvarden 2001), its
detailed description is supplied according to the Japanese
material. The voucher specimen collected in Japan is deposited
in the herbarium of the Applied Institute of Ecology,
Chinese Academy of Sciences (IFP), and duplicates were
forwarded to the Mycological Herbarium of Forestry and
Forest Products Research Institute, Japan (TFM), and the
Herbarium of National Museum of Science, Japan (TNS).
The microscopic method used in this study is the same as
that described by Cui et al. (2007).
