Inner peridial hyphae pseudoparenchymatous, formed by subglobose, vesiculose to angular hyphae 15 to 35 µm in diameter.

Basidia clavate, 8 to 15 µm long, 6 to 8 µm wide, simple-based, generally with 6 sterigmata.

Spores cylindrical-ellipsoidal to irregular, smooth, hyaline, thick-walled, 7 to 9.5 µm long, 4.5 to 6 µm wide, with homogeneous contents, and inamyloid in Melzer's reagent.
