Lamellar edge without elements differentiated from basidia or basidioles.

Basidia clavate, 22 to 35 µm long, 5 to 7 µm wide, with basal clamp connections and four-spored.

Spores ellipsoidal, smooth, hyaline, thin- to slightly thick-walled, 5.5 to 7.5 µm long, 3 to 4 µm wide, with an eccentric apiculus at one end, containing one or more oil droplets of varying size inside, and inamyloid in Melzer's reagent.
