Pileipellis composed of filamentous hyphae, arranged in parallel, up to 10 µm wide, moderately thick-walled, with brown intracellular pigment, fine and abundant yellowish-brown incrustations, septate and with prominent clamps.

Cheilocystidia very abundant, rendering the gill edge virtually sterile, subcapitate to lageniform, up to 50 µm long and a maximum width of 10 µm, thin-walled, with faint brown intracellular pigment.

Basidia clavate, up to 35 µm long, with basal clamps, 2- or 4-spored.

Spores ellipsoidal to subfusiform, thick-walled and moderately verrucose, yellowish-brown in water under the microscope, with abundant darker warts, an inconspicuous eccentric apiculus at one end, slightly darkening in KOH, distinctly dextrinoid in Melzer's reagent.
