On dead wood of deciduous broadleaf trees, highly cosmopolitan, forming colonies of numerous specimens, with a fan-shaped pileus, concentrically zoned, displaying contrasting colors ranging from brownish to brown, occasionally with bluish tones, 4 to 5 circular to angular pores per mm, pale cream, and cream-colored flesh of coriaceous texture.

Trimitic hyphal system, with thick-walled skeletal hyphae, hyaline, 4 to 8 µm wide, aseptate; hyaline, thin-walled generative hyphae, 2.5 to 3 µm wide, septate and with clamp connections; and thick-walled binding hyphae, profusely branched, 2 to 4 µm wide.

Without cystidia, but with cystidioles present in the hymenium, of dimensions similar to basidia, fusiform, 15 to 19 µm long, 4 to 5 µm wide, with basal clamp connections.

Basidia clavate, 15 to 20 µm long, 4 to 6 µm wide, with basal clamp connections, 4-spored.

Spores cylindrical, slightly allantoid, smooth, hyaline, thin-walled, with an eccentric apiculus at one end, 5 to 6.5 µm long, 2 to 2.5 µm wide, containing small oil droplets of various sizes inside, inamyloid in Melzer's reagent.
