Coprinopsis nivea

Veil hyphae of the suprapellis spherical to ovoid, very large (up to 60 µm or more), smooth, hyaline or very slightly encrusted, interspersed with scarce slender filamentous hyphae (3 to 9 µm wide).

Cheilocystidia abundant, subglobose, pyriform to utriform, large, exceeding 80 µm in length.

Pleurocystidia of similar morphology, but larger, exceeding 140 µm in length.

Spores short ellipsoidal, slightly angular, very dark brown under the microscope, with a minute slightly eccentric apiculus at one end and a truncated central germ pore at the opposite end.
