  Pileus up to 4-15(-20) x 3-12 mm when still closed, up to 30 mm when expanded, first globose or sometimes ellipsoid, ovoid or conical, then hemispherical or obtusely conical, finally convex, white. Veil first white and covering whole pileus, then breaking up around centre in felty patches, later becoming brownish in part. Lamellae, L = 32-38, l = 0-3(-5), free, first white, then grey-brown, finally blackish. Stipe up to 60 x 1-3(-4) mm, whitish; base somewhat clavate, up to 5 mm.
  Spores [220,11,9] 6.2-8.7 x 5.3-8.2 x 4.8-6.5 µm, short ovoid or subglobose and truncate, lentiform, generally very dark red-brown, with central, 1.3-1.5 µm wide germ pore; Q = 1.00-1.35, av. Q = 1.05-1.25; av. L = 7.0-8.0, av. B = 6.1-7.6 µm. Basidia 12-34 x 7-9 µm, 4-spored, surrounded by 4-7 pseudoparaphyses. Pleurocystidia 50-120 x 20-40 µm, subcylindrical, oblong and then often conical towards apex or fusiform. Cheilocystidia 40-85 x 25-45 µm, subcylindrical, oblong, (broadly) ellipsoid, fusiform or subutriform. Elements of veil thin-walled, diverticulate, 2-5(-7) µm wide, slightly incrusted. Clamp-connections present.

Habitat & distribution

  Solitary or a few together; often on burned places but also on bare, often clayey soil. Widespread but not common in Europe.

Remarks

  Coprinus gonophyllus can be recognized by the rather firm, usually hemispherical basidiocarps which often grow on burnt places and the thin-walled, narrowly velar hyphae and the short, subglobose spores with truncate germ pore. The size of the spores is somewhat similar to that of Coprinus spilosporus, but that species has long, thick-walled hairs between the velar elements. Another taxon, named Coprinus spec. Bas 5002 in the present paper, is close to C. gonophyllus but differs in smaller, (sub)globose spores with an apical papilla (limoniform). Coprinus epichloeus is a much smaller and fragile species with spores which are not distinctly truncate at apex.
