Cheilocystidia very abundant, cylindrical to clavate, hyaline, thin- to slightly thick-walled, septate, the terminal cell 12-30 µm long and 11-14 µm wide, with basal clamps.

Pleurocystidia absent.

Basidia cylindric-clavate, 27-37 µm long and 11-14 µm wide, with yellowish granulations inside, with basal clamps, generally 4-spored.
