On decaying wood of broadleaved trees, preferentially Quercus sp., with completely resupinate basidiomata tightly adnate to the substrate, with an undulating to wrinkled/merulioid surface, ochre to reddish-brown, with a well-defined whitish growth margin, and gelatinous when fresh, turning coriaceous upon drying.

Hyphal system monomitic; subicular hyphae hyaline, moderately thick-walled, 2 to 3 µm wide, septate with clamp connections.

Leptocystidia cylindrical to sinuous, 50 to 100 µm long and 8 to 11 µm wide.

Basidia cylindrical-clavate, 18 to 25 µm long, 3.5 to 5 µm wide, clamped at the base, 4-spored.

Spores ellipsoidal, smooth, hyaline, thin-walled, 5.5 to 6.5 µm long, 2.2 to 2.7 µm wide, with a tiny lateral apiculus at one end, containing small guttules inside, inamyloid in Melzer's reagent.
