Filamentous cuticle composed of cylindrical hyphae arranged more or less parallel, 4 to 9 µm wide, with a light brown pigment inside, septate with clamp connections.

Cheilocystidia abundant, cylindrical to slightly lageniform, sinuous, hyaline, thin-walled, 25 to 45 µm long, with a maximum width of 5 to 8 µm.

Without pleurocystidia.

Basidia cylindric-clavate, 15 to 25 µm long by 5 to 8 µm wide, with basal clamp connections and tetrasporic.

Spores ovoid to slightly amygdaliform, smooth, hyaline, thin-walled, with a discreet eccentric apiculus at one end, 4.5 to 6.5 µm long by 3.5 to 4.5 µm wide, containing oil drops of varying sizes inside, and inamyloid in Melzer's reagent.
