Taxomic examinations of five powdery mildew fungi found on two new host plants in Japan, rosemary (Rosmarinus o$cinalis, fam. Labiatae) and downy thorn apple (Datura metel, fam. Solanaceae), and on blue gum (Eucalyptus globulus, fam. Myrtaceae) on which the causal fungus is still indeterminate in Japan, were carried out. Between two anamorphic types found on blue gum, the fungus of Euoidium type was identified to be Oidium state of Sphaerotheca aphanis var. aphanis. Another one, Pseudoidium type was regarded as a new Oidium species, O. eucalypti-globuli. The fungus of Euoidium type on downy thorn apple was identified with the anamorphic state of Erysiphe orontii, but it was not able to specify that of Pseudoidium type. The anamorph on rosemary morphologically agreed well with that of Erysiphe galeopsidis observed on various plants of the Labiatae.
