Pileipellis filamentous, composed of densely interwoven hyphae up to 9 µm wide, septate and clamped, overlaid by short hyphae with swellings and short digitations pileocystidia-like, reaching up to 20 µm wide.

Cheilocystidia cylindrical to clavate, with apical swellings and finger-like outgrowths, up to 40 µm long, with basal clamps.

Basidia clavate, up to 27 µm long and up to 7.5 µm wide, with basal clamps, 4-spored.

Spores cylindric-ellipsoidal, smooth, hyaline, thin-walled, with a prominent eccentric apiculus at one end, vacuolar internal content, inamyloid in Melzer's reagent.
