The very large genus Mycosphaerella, typified by M. punctiformis, has long been known to include a diverse range of relatively non-descript sexual morphs that cause leaf spots. This became more obvious as their asexual morphs were explored and determined to belong to numerous genera (Sivanesan 1984, Crous & Braun 2003). Crous et al. (2009b, 2011b) determined that M. punctiformis, now regarded as Ramularia endophylla (Videira et al. 2015a), belongs in Ramularia typified by R. pusilla, thus Mycosphaerella and Ramularia are synonyms. Crous et al. (2009b, 2011b) and others have also determined that most of the 1738 names placed in Mycosphaerella are not congeneric with the type of the genus such that many species have already been placed in segregate genera including Batcheloromyces, Delphinella, Passalora, Pseudocercospora, Stenella, and Pseudocercospora amongst many others (Farr & Rossman 2015). Although Mycosphaerella includes many names, those that are congeneric with the type species are relatively few. Around 225 names in Mycosphaerella have been reported to be morphologically indistinguishable from M. punctiformis (Aptroot 2006) and are thus likely to belong to Ramularia. Given the extreme morphological convergence of the sexual morphs placed in Mycosphaerella and confusion associated with these names, the use of the generic name that has priority, Ramularia, for the species of Mycosphaerella sensu stricto as already reflected in the recent literature (Videira et al. 2015b), is recommended.

Ramularia Unger 1833

Ramularia species are usually described as hyphomycetes with hyaline conidiophores and conidia with distinct, thickened, darkened and refractive conidial loci and hila. Braun (1998) divided the genus Ramularia in two morphologically circumscribed subgenera, one with conidia consistently solitary (Ramularia subgen. Ramularia) and another with catenate conidia (Ramularia subgen. Septocylindrium, type species R. septata). Within Ramularia subgen. Ramularia, two sections were established, one with conidiogenous cells straight to geniculous-sinuous (Sect. Ramularia,typeRamularia pusilla) and one with conidiogenous cells strongly curved like a swan's neck (Sect. Ophiocladium,type species R. collo-cygni). Ramularia species are phytopathogenic and mostly cause leaf spots but they can also be endophytic, saprophytic and mycophylic. There are about 325 species accepted in this genus (Braun 1998, or MycoBank) of which only six have thus far been experimentally linked to a Mycosphaerella sexual morph (Videira et al. 2015b). Currently Ramularia is accepted as being a hostspecific genus of phytopathogenic fungi (Braun 1998) …
