title: Fourteen coprophilous species of Psathyrella identified in the Nordic countries using morphology and nuclear rDNA sequence data.
abstract: Psathyrella species growing on dung or occasionally on dung in the Nordic countries were studied using morphological characters and nu-rDNA sequence data and type collections were examined when available. Fourteen species capable of growing on dung were identified. Descriptions are given of all dung-inhabiting species and to a lesser extent of the species occasionally growing on dung. Three new species are described: Psathyrella fimiseda, P. merdicola, and P. scatophila. P. stercoraria is described as a new species in order to validate the name. A key to the coprophilous species in Europe including the species described by Peck & Smith from North America is provided. The phylogenetic analyses recovered four major supported clades within Psathyrellaceae corresponding to Parasola, Coprinopsis, Lacrymaria/Spadiceae pro parte, and Psathyrella. The status of Coprinellus was ambiguous. The current morphology-based infrageneric classification of Psathyrella was not supported by the phylogenetic analyses and a coprophilous habit has apparently evolved on multiple occasions. Three new combinations are proposed: Parasola conopilus, Coprinopsis marcescibilis, and Coprinopsis pannucioides.
