Cuticle formed by filamentous hyphae, smooth, hyaline, thin-walled, 3 to 5 µm thick, interwoven, containing faint ochraceous pigment inside, septate and with clamp connections at the septa.

Lamellar edge without elements differentiated from basidia or basidioles.

Basidia clavate, 28 to 35 µm long, 6 to 8 µm wide, with basal clamp connections and four-spored.

Spores cylindrical-ellipsoidal, smooth, hyaline, thin-walled, 4.5 to 7 µm long, 2 to 3 µm wide, with an eccentric apiculus at one end, containing abundant oil droplets of varying size inside, and inamyloid in Melzer's reagent.
