A new species of Phellinus (Hymenochaetaceae) growing on bamboo in tropical China

Phellinus bambusicola sp. nov. is described and illustrated from Hainan Province, southern China. It has annual and resupinate basidiocarps, clay-buff to pale fawn pore surface, abundant hymenial setae, broadly ellipsoid and thin-walled basidiospores, setal hyphae present in the subiculum but absent at the sterile margin, and a growth on bamboo. The new species is similar to Phellinus ferruginosus, but the latter has an annual to perennial growth habit, yellowish brown to dark reddish brown pore surface, smaller pores (6-8 per mm), setal hyphae present at the sterile margin, and narrowly ellipsoid basidiospores.
