 Description: Basidiocarp annual, effused-reflexed or sessile. Pilei solitary, dimidiate, up to 2 × 3 × 4 cm. Upper surface ivory to brown, glabrous, azonate or faintly zonate, shallowly sulcate; margin ivory glabrous, rounded. Pore surface ivory, the pores circular, 3-5 per mm, with very thick. Context white to tan, faintly zonate, firm-corky, up to 4 mm thick. Tube layers concolorous with the context, indistinctly layered, each layer up to 4 mm thick. Hyphal system, dimitic generative hyphae hyaline, thin-walled, with clamps, rarely branched, 2-4 μm in diam; skeletal hyphae thick-walled, rarely branched, nonseptate, 2.5-4 μm in diam. Basidia broadly clavate, 25-35 × 12-16 μm, with a basal clamp. Basidiospores ellipsoid to ovoid, truncate, hyaline, thick-walled, smooth, dextrinoid, 13-16 × 7-10 μm.
