HyphaZ system trimitic; generative hyphae thin-walled, nodose-septate, 2.5-3 µm in diem; skeletal hyphae thick-walled, aseptate, 3-3.5 µm diam; binding hyphae richly branched, 1.5-3 µm diam; subicular tissue dextrinoid in Melzer's reagent. CystidioZes embedded, blunt-fusiform, 20-26 x 5-7 µm, with a basal clamp; hyphal pegs present. Basidia short-clavate to subglobose, 4-sterigmate, 19-22 x 7-10 µm, with a basal clamp. Basidiospores hyaline, smooth, thick-walled, often appearing truncate, dextrinoid in Melzer's reagent (reaction sometimes variable), ellipsoid to ovoid, 5.5-8.5 x 4-5 µm.
