More smooth-spored species of Inocybe (): type studies and 12 new species from Europe.

Twelve new species of () are described from Europe on the basis of detailed morphological and molecular investigation. A portrait of the recently described is given. All species are smooth-spored and some pruinose only in the apical part of the stipe, and some on entire length. The new species are compared to 24 type specimens (17 characterized by at least partial ITS sequence data), all of which are described and revised here. Epitypes were selected for two species, . Based on our studies, we confirm that and on one hand, and and on the other, are synonyms and furthermore suggest that is synonymous with with with . All of the new species are supported by phylogenetic analyses. Among the 16 previously described species accepted here, 10 are represented by types in the phylogenetic analyses and five by own collections corresponding to the type. Two species, (remaining doubtful) and are only treated morphologically. In summary, we describe as new or verify the taxonomic status and provide or corroborate morphological concepts for 37 smooth-spored species of . : Bandini D, Oertel B, Eberhardt U. 2022.
