Cuticle formed by cylindrical, hyaline hyphae arranged parallel, 3.5 to 12 µm wide, with emergent subcylindrical to lageniform pileocystidia 40 to 60 µm long and 12 to 20 µm wide.

Caulocystidia present, lageniform, slightly capitate, 35 to 50 µm long and 8 to 13 µm wide.

Cheilocystidia subcylindrical to lageniform, subcapitate, 35 to 55 µm long and 8 to 13 µm wide.

Pleurocystidia scattered, of similar morphology, 35 to 45 µm long and 7 to 11 µm wide.

Lamellar trama regular or parallel.

Basidia subcylindrical to clavate, 25 to 35 µm long, 4.5 to 6 µm wide, with basal clamp connections and four-spored.

Spores cylindrical-ellipsoidal, smooth, hyaline, thin-walled, 4 to 6 µm long, 2.5 to 3.5 µm wide, with an inconspicuous apiculus at one end, containing oily granular content inside, and inamyloid in Melzer's reagent.
