Hyphal system monomitic; subicular hyphae smooth, hyaline, thin- to slightly thick-walled, 4 to 10 µm wide, the basal ones encrusted, septate predominantly with simple septa.

Leptocystidia fusiform to lageniform, smooth, thin-walled, 55 to 70 µm long and 4 to 6 µm wide at the base.

Basidia cylindrical-clavate, 25 to 35 µm long, 5 to 6 µm wide, simple-septate at the base (unclamped), 4-spored.

Spores ellipsoidal, smooth, hyaline, thin-walled, 4.5 to 5.5 µm long, 2.5 to 3 µm wide, with a slightly pointed apicular end, containing guttules of varying sizes, inamyloid in Melzer's reagent.
