Caulocystidia present on the stipe surface, subulate, septate, thick-walled, with brown pigment inside.

Basidia cylindric-clavate, 25 to 40 µm long by 5 to 6 µm wide, with basal clamp connections and tetrasporic.

Spores cylindric-ellipsoidal to very slightly allantoic, smooth, hyaline, thin-walled, 4.5 to 7 µm long by 2 to 3 µm wide, with small oil drops inside, and with a very weakly amyloid reaction in Melzer's reagent.
