Coprinus Pers. and the disposition of Coprinus species sensu lato

Summary Redhead, S. A., Vilgalys, R., Moncalvo, J.‐M., Johnson, J. & Hopple, J. S., Jr.: Coprinus Pers. and the disposition of Coprinus species sensu lato. – Taxon 50: 203–241. 2001. –1SSN 0040–0262. Based upon molecular studies, the genus Coprinus Pers. is subdivided into Coprinus sensu stricto ( Agaricaceae ), and Coprinellus P. Karst., Coprinopsis P. Karst., and Parasola gen. nov. in the new family Psathyrellaceae. The nomenclatural history and typifications of names previously treated as synonyms of Coprinus are reviewed. It is demonstrated that taxonomic characters previously considered not to be generically significant gain importance when correlated with molecular evidence. Many new combinations are proposed. A key using anatomical features to molecularly (phylogenetically) recognised coprinoid genera is provided.
