Phellinus noxius (Corner) Cunningham, Bull. N.Z.Dep. Sci. Ind. Res. 164: 221. 1965.

 Description: Basidiocarp perennial, pileate, effused-reflexed to resupinate, solitary to imbricate, broadly attached, consistency woody hard; pileus dimidiate, flat or semiungulate, up to 13.5 cm wide, and 1-5.5 cm thick; pilear surface first finely velvety and pale ferruginous to umber in concentric zones, soon glabrous in irregular sulcate zones and dark brown to black, covered with a 0.2-1 mm thick, resinous, hard crust, pore surface fulvous to dark bay or fuscous, pores small and round, 8-10 per mm, tubes each layer separated by a 1-3 mm thick dark brown context layer, in total up to 1 cm thick. Hyphal system dimitic; generative hyphae simple-septate, hyaline to pale yellowish, 2 µm wide; skeletal hyphae yellow to bay, 3-6 µm wide. Setal hyphae abundant in the tubes, thin-walled, dark brown to ferruginous, obtuse, up to 100 × 7.5-13 µm, in the context yellow to ferruginous, obtuse to blunt, up to 700 × 5-10 µm. Basidiospores broadly ellipsoid to ovoid, hyaline and thin-walled, 3.5-4.5 × 3-3.5 µm.

 Note: This species is recognized by its obtuse setal hyphae partly projecting into the hymenium and the absence of hymenium setae. The fungus causes brown root rot of many tree species in Taiwan.
