NEW SPECIES OF MYCOSPHAERELLA OCCURRING ON EUCALYPTUS LEAVES IN INDONESIA AND AFRICA

Although Africa and Indonesia have not been particularly well surveyed for Mycosphaerella leaf spot fungi, several species are known to occu r on Eucalyptus leaves in these areas. Three new species of Mycosphaer ella with anamorph states are described from herbarium specimens and c ultures in the present study. Mycosphaerella suttoniae and Mycosphaere lla heimioides are described from Eucalyptus leaves from Indonesia. Th e former species is of particular interest, because its anamorph Phaeo phleospora 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. B oth M. irregulariramosa and M. heimioides have Pseudocercospora anamor phs, 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 Mycosp haerella on Eucalyptus leaves in other parts of Africa and in Indonesi a.
