Cystidia and other sterile hymenial elements absent.

Basidia subcylindrical to clavate, 15 to 21 µm long, 6 to 9 µm wide, with basal clamp connections, bearing 4 to 6 sterigmata.

Spores ellipsoidal, smooth, hyaline, thin-walled, with an eccentric apiculus at one end, 5.5 to 8 µm long, 2.5 to 4 µm wide, containing one or more oil droplets of varying size inside, and inamyloid in Melzer's reagent.
