Filamentous pileipellis, with an outer layer of slender hyphae, hyaline or slightly pigmented ochraceous, widely separated by gelatinization and clamped. Below these, a layer of broader, compacted hyphae, parallel to slightly interwoven, also clamped.

Lamellar edge with scattered cylindrical to pyriform elements, similar in morphology to basidioles.

Basidia clavate, up to 38 µm long, with basal clamp connections, 4-spored.

Spores ellipsoidal to fusiform (almond-shaped), very large, finely verrucose-walled, yellow under the microscope, with minute darker warts, an eccentric apiculus, and without appreciable reaction in Melzer's reagent.
