The genus Mycosphaerella and its anamorphs

More than 2000 names have been described in Mycosphaerella and Sphaerella ( Dothideales). Based on various morphological features depicted by earlier w orkers, six sections are recognized in the genus. About 27 anamorph genera have been linked to Mycosphaerella, 23 of which are recognized here. Based on phylogenetic analyses of the ITS-1, 5.8S and ITS-2 DNA sequence data of 46 species of Mycosphaerella species (58 strains), one large cluster was di stinguished containing primarily taxa with cercosporoid anamorphs, as well as another smaller cluster for species with Dissoconium anamorphs.
