Lamellar edge: Lacking clearly differentiated cheilocystidia, but lined with abundant sterile terminal hyphae of various shapes (fusiform, ventricose, clavate), similar in size to basidia.

Basidia: Clavate, 25-30 x 5-7 µm, with basal clamp connections, 4-spored.

Spores: Ellipsoid to amygdaliform, thin-walled, hyaline, with a distinct eccentric apiculus, containing lipid droplets.
