Multi-locus phylogeny and taxonomy of .

includes a number of plant pathogenic, saprobic and clinically relevant fungi. Some of these species are of great importance in human activities, but the genus has never been revised in a phylogenetic framework. In this study, we revise based on available ex-type cultures from worldwide collections, observation of the holotypes and/or protologues, and additional isolates from diverse substrates and geographical origins. Based on nine nuclear loci, i.e., ITS, LSU, , , , , , and , as well as phenotypic data, the genus and species boundaries are assessed for . Three species, i.e., , and , are excluded from the genus and reallocated in and , respectively, whereas and are confirmed as members of . is revealed as conspecific with species previously described in such as , , , , and . Additionally, is revealed as synonym of , and of . A total of 11 phylogenetic species are described, illustrated and discussed, including one novel taxon, The placements of 15 other doubtful species are discussed, and is validated.
