Cortina absent. - Context whitish, not reddening upon exposure. - Odor not distinctive or weakly spermatic. - Taste not distinctive.
Spore print brown. - Basidiospores 8.5-10.5 — 8-9.5 µm, ovoid, distinctly nodulose, hemispherical or obtuse-conical projections (nodules) 2-2.5 µm high, yellow-brown. - Basidia 20-34 — 7-10 µm, 4-spored, clavate, clamped. - Cheilocystidia 40-60 (-70) — 12-20 (-24) µm, broadly fusoid or utriform, hyaline or rarely also yellow-brown wall metuloid, up to 4-5 µm thick at apex, crystals present. - Paracystidia (10-) 15-30 — 7-15 µm, vesiculose or clavate, numerous, hyaline wall thin, pigment absent. - Pleurocystidia size and shape like cheilocystidia. - Caulocystidia size and shape like cheilocystidia, but less metuloid, intermixed with clavate, thin-walled cells. - Pileipellis an (ixo)cutis of repent (or suberect) cylindrical hyphae, (2-) 4-8 (-10) µm diam.; terminal cells not differentiated, non-gelatinized or weakly gelatinized wall encrusted with yellow-brown pigment.
