Basidiocarp resupinate, effused reflexed to more rarely distinctly pileate, often widely effused as shelflike, tough and coriaceous, upper surface glabrous, zoned, at first white to cream, soon covered by a reddish cuticle starting from the base, individual pilei up to 1 cm thick at the base. Pore surface white to cork colored, pores angular to semidaedaleoid, especially on sloping parts of the basidiocarp, 2-3 per mm, but individual elongated pores up to 6 mm long, tubes concolorous, up to 5 mm deep, context white, tough up to 3 mm thick, in section with a distinct dark line where covered with the reddish to bay colored cuticle. Hyphal system trimitic, generative hyphae with clamps, thin-walled, 1.5-4 μm wide, skeletal hyphae dominate, thick-walled to solid, hyaline, 3-6 μm wide, binding hyphae as skeletal hyphae but branched. Basidiospores cylindrical to oblong ellipsoid, thin-walled and hyaline, IKI-, 8-12.5 × 3.5-5 μm.
