peeling but dry. Stipe: White, almost straight thickening towards
the base. Gills: Free, crowded, initially pale changing to
black and autodigesting. Spore print: Black liquid.
Microscopy: Basidia: 4-spored. Spores: Broadly ellipsoid to ovoid, smooth with
central germ pore (1.8-2.7µm); L= 12.4-17.3µm,
W = 7.3-10.2µm, Q=1.55-1.80, Qm=1.69
The spores in this specimen are larger than the
reported sizes for Coprinus comatus.
