Cheilocystidia not observed; described in literature as fusiform to clavate, 9–25 µm long by 10–12 µm wide, with warts up to 1.5 µm on their surface.

Basidia clavate, 13–20 µm long by 7–9 µm wide, with basal clamps, 2-spored.

Spores short-ellipsoidal to oblong, with a pointed end where the apiculus is located, measuring 7.5–10 µm long by 4.5–6.5 µm wide, containing oil droplets of varying size inside, amyloid in Melzer's reagent.
