Habitat: On weathered dung of herbivores (especially cattle and horses). Notes: Common and widespread.   Based on recent molecular studies published by Hopple & Vilgalys in 1999 (Molecular Phylogenetics & Evolution 13: 1-19), Redhead, Vilgalys, Moncalvo, Johnson & Hopple (2001. Taxon 50: 203-241) recently split the large and well-known agaric genus Coprinus Pers. taxonomically into four genera and two families. Coprinus comatus , the universally recognized lectotype for Coprinus , and two other species are now recognized as belonging with Lepiota and Agaricus in the Agaricaceae. This transfer renders the younger name (Coprinaceae) synonymous and superfluous. Over 95% of the remaining former Coprinus species are now treated with Psathyrella in a separate family, for which the name Psathyrellaceae has been proposed. Except for C. comatus and close allies, all former Coprinus species have now been distributed into Coprinopsis, Coprinellus, and Parasola within the Psathyrellaceae. Lorelei Norvell (2001)

Habitat: On soil amongst grass in unimproved grassland, parkland, on lawns and along woodland edges (but not in woodland). Notes: Common and widespread but undoubtedly over-recorded. This is a grassland taxon and therefore any 'plicatilis' in other habitats should be examined microscopically.

Unlikely to be mistaken for anything else, except C. episcopalis which often resembles small basidiomes of C. picaceus. but is much rarer and very localised.   Based on recent molecular studies published by Hopple & Vilgalys in 1999 (Molecular Phylogenetics & Evolution 13: 1-19), Redhead, Vilgalys, Moncalvo, Johnson & Hopple (2001.
