Remarks (public):This is one of the largest polypores in the tropics. The main characteristics are the ungulate, fulvous to dark brown pileus without a distinct cuticle, the obtuse, often velutinate margin, the swollen setae, and the rather large, subglobose basidiospores.

Description:Phellinus setulosus (Lloyd) Imazeki, Bull. Tokyo Sci. Mus. 6:104, 1943. - Fomes setulosus Lloyd, Mycol. Writ. 4:243, 1915.
Basidiocarps perennial, effused-reflexed to pileate, solitary or imbricate, dimidiate, broadly attached, convex to ungulate, up to 22 cm broad, 12 cm wide and 10 cm thick near the base, woody hard when dry; pilear surface dull, fulvous to reddish brown becoming blackish, very finely tomentose to glabrous, sometimes basally covered with mosses, broadly concentrically zonate and sulcate, when old rimose, without a distinct cortex, margin fulvous, obtuse and even, often velutinate; pore surface fulvous to ferruginous, pores round and regular, 5-8 per mm, dissepiments entire and fairly thick, tubes single-layered to stratified, each layer 2-5 mm long and often with a greyish tint, sterile margin narrow or up to 5 mm broad; context golden yellow to ferruginous brown, lacking a distinct cuticle above, fibrous, faintly zonate, up to 3 cm thick. Hyphal system dimitic; generative hyphae simple-septate, hyaline to pale yellow, thin- to weakly thick-walled, 3-3.5 µm wide, on average more yellow in the context than in the tubes; skeletal hyphae dominating in the whole basidiocarp, yellow to ferruginous, thick-walled but with a distinct lumen, 3-5 µm wide, unbranched and with a blunt apex.
Hymenial setae abundant to infrequent, ferruginous and thick-walled, subulate to ventricose, often strongly swollen at the base, apex straight or hooked, 15-40 x 5-16(20) µm.
Cystidia absent; cystidioles hyaline, ventricose, with a prolonged apex, 16-30 x 3-5 µm.
Basidia clavate, 7-10 x 4-5.5 µm, with four sterigmata.
Basidiospores subglobose to broadly ellipsoid, pale yellow to fulvous, smooth and thin- to very thick-walled, 5-7 x 4-6 µm.
Substrata. On dead wood.
Distribution. Pantropical, in Asia extending to subtropical China and Japan.
