　Description： Basidiocarp resupinate and woody. Pore surface pale brown to dark brown. Pores angular, elongate, irregular to daedaleoid, 1-3 mm-1. Tubes up to 2 mm long, concolorous with pore surface. Context inconspicuous to thin, up to 0.5 mm thick, concolourous with pore surface. Hyphal system monomitic, hyphae thin- to thick-walled, hyaline, pale yellow to brown, simple-septate, 2.5-5 µm wide. Setal hyphae present both in dissepiments and context, 10-30 µm wide, 100-280 µm long in dissepiments, up to 500 µm long in context, walls up to 10 µm thick, dark brown, pointed terminally; tramal setal hyphae mostly buried in the trama, rarely projecting into hymenium. Hymenial setae abundant, dark brown, fusiform and straight, 25-60 × 5-10 µm. Basidiospores broadly ellipsoid to subglobose, smooth, 5-6.5 × 6.5-9.0 µm, hyaline to pale brown, IKI-.
