Perenniporia formosana T. T. Chang, Mycol. Res. 98: 954. 1994.

 Description: Basidiocarp annual, sessile, applanate, effuse-reflexed, often imbricate, corky to woody. Pileus up to 12 cm in diameter, 1-2 cm thick, semicircular dimidiate, flabelliform, flat to convex; upper surface glabrous, concentrically zoned, sulcate, at first white to cream, soon covered by a reddish brown cuticle starting from the base, buff to chestnut brown. Pores round to angular, 4-6 mm-1; pore surface wood brown to buckthorn brown. Dendrohyphidia abundant in the hymenium and dissepiments, branched, usually forming a head like a cauliflower, hyaline, thick-walled, not encrusted. Basidiospres tear-shaped to globose, hyaline, smooth, thin-walled, dextrinoid, 4.5-5.5 × 5.5-7.0 μm. Hyphal system dimitic, dextrinoid, generative hyphae with clamp connections, thin-walled, 1.5-4.0 μm wide, skeletal hyphae dominant, thick-walled to solid, hyaline to light brown, up to 8.0 μm wide.
