Abstract
Melanoleuca is one of the taxonomically most complicated genera of Agaricomycetes. The aim of this study is taxonomic revision of European specimens confused with M. angelesiana A.H. Sm. and delimitation of four species, M. brachyspora Harmaja, M. graminicola (Velen.) Kühner & Maire, M. rufipes Bon and M. stridula (Fr.) Singer. The research is based on macro- and micromorphological characters and the multigene phylogenetic analyses of a combined (ITS, rpb2, and tef1) dataset. According to the result, the two new species are proposed – M. monticola sp. nov. which accomodates European specimens previously confused with American species M. angelesiana and M. romanensis sp. nov. from Italy. Moreover, American specimens identified as M. angelesiana belongs to three different phylogenetic species (M. angelesiana sensu typi, M. acystidiata aff. and one more separate lineage). M. graminicola is emended and the respective epitype designated. An identification key of the European species of subg. Urticocystis is provided.
