Introduction Many species of the genus Ramularia Unger are phytopathogenic, causing leaf spots on various host plants and have sexual morphs belonging to the genus Mycosphaerella Johanson s. str. The genus Ramularia, published in 1833, is older than Mycosphaerella, introduced in 1884, and has been proposed as preferred name, i.e., Mycosphaerella is now a younger heterotypic synonym of Ramularia. Ramularia species are characterized by having colorless structures, solitary to fasciculate conidiophores forming small to sporodochial fascicles and solitary to catenate conidia with high morphological variation. A combination of morphological features including shape, size and septation of conidia and conidiophores, and conidiogenous loci have been used to identify Ramularia species. Little is known about Ramularia species in Iran. Scattered reports including 23 species were published between 1941 and 2009 in Iran by several mycologists. In recent years, increasing attempts to examine cercosporoid and ramularioid fungi (Mycosphaerellaceae) in Iran have been made, which led to more than 50 first records of such ascomycetes for this country. In this paper, a new species of Ramularia based on Iranian material is described, and new observations on some Ramularia species with a record of a new host plant for a species previously reported from this country are listed.
