Pileipellis composed of parallelly arranged filamentous hyphae, 4-9 µm wide, with yellowish-brown intracellular pigment and abundant darker surface incrustations, septate and clamped.

Caulocystidia present only on the stipe apex, cylindrical to clavate, with basal clamps.

Cheilocystidia abundant, cylindrical, sinuous to clavate, 30-50 µm long and 9-13 µm wide, thin- to moderately thick-walled, with basal clamps.

Pleurocystidia absent.

Basidia clavate, 35-50 µm long and 9-12 µm wide, with basal clamps, 4-spored.

Spores ellipsoidal, large, smooth- and thick-walled, yellowish-brown under the microscope, with an eccentric apiculus at one end and internal oil droplets.
