Ascomata (chasmothecia) are rarely formed on most hosts. Phylogenetic analyses based on rDNA ITS and 28S rDNA data of a wide range of powdery mildew collections of G. orontii s. lat. suggested the genetic heterogeneity of this species, which is undoubtedly not monophyletic. Sequences retrieved from numerous collections referred to as G. orontii (s. lat.) split into three distinct clusters, previously classified as groups 1 to 3, which have been genetically and morphologically analyzed, circumscribed and named. One cluster (group 2), including a sequence retrieved from powdery mildew on the type host of Erysiphe orontii, Misopates orontium, constitutes G. orontii s. str. G. tabaci comb. nov. ( Erysiphe tabaci) is introduced for the second cluster referring to group 1 that is genetically and morphologically clearly distinct from G. orontii s. str. The third assemblage of sequences (group 3) comprises powdery mildews on hosts of the composite tribe Cichorieae, including Cichorium and Lactuca spp., and a wide range of hosts belonging to various other plant families for which the name G. bolayi sp. nov. is proposed. Oidium lactucae-debilis on Ixeris japonica in Asia is tentatively reduced to synonymy with G. sonchicola, i.e., it does not pertain to the G. orontii s. lat. complex. G. orontii s. lat. on Vinca spp. (Apocynaceae), only known as asexual morph, represents a separate species only distantly related to G. orontii s. str., which is described herein as G. vincae sp. nov. G. spadiceus is a further plurivorous Golovinomyces species discussed in this work, which, however, does not belong to the G. orontii complex. } }
