|Publication abstract=''Ramularia'' is a species-rich genus that harbours plant pathogens responsible for yield losses to many important crops, including barley, sugar beet and strawberry. Species of ''Ramularia'' are hyphomycetes with hyaline conidiophores and conidia with distinct, thickened, darkened, refractive conidiogenous loci and conidial hila, and ''Mycosphaerella'' sexual morphs. Because of its simple morphology and general lack of DNA data in public databases, several allied genera are frequently confused with ''Ramularia''. In order to improve the delimitation of ''Ramularia'' from allied genera and the circumscription of species within the genus ''Ramularia'', a polyphasic approach based on multilocus DNA sequences, morphological and cultural data were used in this study. A total of 420 isolates belonging to ''Ramularia'' and allied genera were targeted for the amplification and sequencing of six partial genes. Although ''Ramularia'' and ''Ramulariopsis'' proved to be monophyletic, ''Cercosporella'' and ''Pseudocercosporella'' were polyphyletic. ''Phacellium'' isolates clustered within the ''Ramularia'' clade and the genus is thus tentatively reduced to synonymy under ''Ramularia''. ''Cercosporella'' and ''Pseudocercosporella'' isolates that were not congeneric with the ex-type strains of the type species of those genera were assigned to existing genera or to the newly introduced genera ''Teratoramularia'' and ''Xenoramularia'', respectively. ''Teratoramularia'' is a genus with ramularia-like morphology belonging to the ''Teratosphaeriaceae'', and ''Xenoramularia'' was introduced to accommodate hyphomycetous species closely related to ''Zymoseptoria''. The genera ''Apseudocercosporella'', ''Epicoleosporium'', ''Filiella'', ''Fusidiella'', ''Neopseudocercosporella'', and ''Mycosphaerelloides'' were also newly introduced to accommodate species non-congeneric with their purported types. A total of nine new combinations and 24 new species were introduced in this study.
