Monomitic hyphal system with hyaline, thin-walled generative hyphae 2 to 5 µm wide, with clamped septa.

Marginal hairs thick-walled, up to 3.5 µm wide, thoroughly encrusted with acicular crystals up to 4 µm long, except at the smooth extreme apex.

Basidia clavate, with basal clamp connections, predominantly 2-spored.

Spores very scarce in mounts, ellipsoidal to slightly navicular, smooth, hyaline, thin-walled, with vacuolar content (measuring 7–10 x 3.5–4.5 µm according to literature).
