Pileipellis cellular, composed of subglobose to pyriform cells 20 to 50 µm in diameter, containing pale brownish intracellular pigment.

Caulocystidia subcylindrical, fusiform to lageniform, clustered in fascicles.

Cheilocystidia pyriform, clavate to lageniform, 35 to 50 µm long and 11 to 16 µm wide, often bearing small apical droplets.

Pleurocystidia fusiform to lageniform, 65 to 75 µm long and 12 to 15 µm wide.

Basidia clavate, 35 to 40 µm long, 13 to 16 µm wide, clampless at the base, 2- or 4-spored.

Spores ellipsoidal, dark brown under the microscope, 12 to 15 µm long, 7 to 8 µm wide, with a tiny eccentric hyaline apiculus at one end and a conspicuous central germ pore at the opposite pole.
