Suprapellis formed by subglobose to ovoid hyphae up to 40 µm in diameter, hyaline or with only faint ochraceous intracellular pigment, mixed with some hyphoid filamentous elements up to 8 µm wide.

Subpellis formed by filamentous, hyaline, densely interwoven hyphae with clamped septa.

Lamellar edge homomorphic, without differentiated elements from basidia or basidioles.

Basidia clavate, short, up to 25 µm long, with basal clamp connections, 4-spored.
