Without cystidia.

Lamellar trama regular or parallel.

Basidia cylindric-clavate, 25 to 30 µm long, 6 to 8 µm wide, with simple base (not clamped), 4-spored.

Spores ellipsoid, smooth, hyaline, thin-walled, with an eccentric apiculus at one end, 5.5 to 7.5 µm long, 4 to 5.5 µm wide, containing a large oil or lipid droplet inside, inamyloid in Melzer's reagent.
