New species of Mycosphaerella occurring on Eucalyptus leaves in Indonesia and Africa
Canadian Journal of Botany - Revue Canadienne de Botanique 75 (5), 781-790
Abstract: Although Africa and Indonesia have not been particularly well surveyed for Mycosphaerella leaf spot fungi, several species are known to occur on Eucalyptus leaves in these areas. Three new species of Mycosphaerella with anamorph states are described from herbarium specimens and cultures in the present study. Mycosphaerella suttoniae and Mycosphaerella heimioides are described from Eucalyptus leaves from Indonesia. The former species is of particular interest, because its anamorph Phaeophleospora epicoccoides is the first species of Phaeophleospora linked to Mycosphaerella. Mycosphaerella irregulariramosa is described from Eucalyptus saligna growing in the Northern Province of South Africa. Both M. irregulariramosa and M. heimioides have Pseudocercospora anamorphs, and these are described as Pseudocercospora irregulariramosa and Pseudocercospora heimioides. Notes are also provided on the host range and geographic distribution of previously described species of Mycosphaerella on Eucalyptus leaves in other parts of Africa and in Indonesia.
