abstract = {Ascospore septation was used by Saccardo as a primary character to separate genera in the Dothideales (Ascomycetes). The genus Sphaerulina (3- to multi-septate ascospores) was thus distinguished from Mycosphaerella (1-septate ascospores). Several species in Sphaerulina have been found to have anamorphs commonly associated with Mycosphaerella. Sequence data derived from the rDNA (ITS 1, 5.8S and ITS 2) gene suggest that Sphaerulina is heterogeneous, and that species with Mycosphaerella-like anamorphs belong in Mycosphaerella, while those with yeast-like anamorphs belong to the Dothioraceae. Mycosphaerella sphaerulinae and its Pseudocercospora sphaerulinae anamorph are newly described from leaf spots of Eucalyptus globulus and E. nitens in Chile. Sphaerulina eucalypti, which occurs on Eucalyptus leaves in South Africa, is transferred to Sydowia. This species is also newly linked to its anamorph, Selenophoma eucalypti. This study contributes to growing phylogenetic evidence that ascospore septation is a poor indicator of generic status in the Ascomycetes.}
