Basidiocarps centrally stipitate. Pileus circular, plane or depressed in the center, 1.9-5 cm in diameter, up to 3 mm thick; pileus surface wrinkled, light brown to grayish-brown (10YR5-7/4), margin round with inconspicuous lobes.

Stipe cylindrical, up to 1.5 cm long, up to 5 mm in diameter, wrinkled, pale orange (10YR8-9/4) at the top, otherwise covered with a grayish-brown to dark brown (10YR3-5/2) crust or without a crust. Context soft corky, brittle, 0.2-1.2 mm thick, pale orange (10YR9/4), without a crust.

Pore surface light brown (10YR6-7/4-8), pores angular, 2-3/mm, dissepiments thin, slightly dentate. Tubes pale orange (10YR7- 9/4), up to 2 mm deep.

Hyphal system dimitic with generative hyphae and skeletal- binding hyphae. Contextual generative hyphae 2-5 ?m in diameter, thin-walled, hyaline, with clamp connections. Contextual skeletal-binding hyphae thick-walled to solid, frequently branched, interwoven, hyaline, 2.5-5 ?m in diameter. Tramal generative hyphae 2-5 ?m in diameter, thin-walled, hyaline, with clamp connections. Tramal skeletal- binding hyphae 2-5 ?m in diameter, otherwise as in context. Crust on stipe composed of coralloid-binding hyphae with clavate tips, hyphae thick-walled, highly agglutinated. Basidia clavate, 17.5-37.5 × 4-8 ?m, with a basal clamp, 4-sterigmate.
