A new subgenus, Microidium, of Oidium (Erysiphaceae) on Phyllanthus spp.

A new subgenus, Microidium, of Oidium (Erysiphaceae) on Phyllanthus spp.

Powdery mildew fungi found on leaves, shoots, and stems of Phyllanthus acidus, P. amarus, and P. reticulatus proved to be a fungus having morphology unique in the Erysiphaceae. Light micrographs of a new germination pattern are added to discuss differences to other four germination patterns of the p...
