Erysiphe alphitoides is a species of powdery mildew in the family Erysiphaceae. It is found across the world on every continent bar Antarctica, where it primarily infects plants in the genus Quercus (oaks). It has also been recorded with varying degrees of likelihood on other plants, including Aesculus (horse chestnut), Castanea (sweet chestnut), Fagus (beech) and Wisteria.

Podosphaera fusca is a fungus that parasitically infects plants (a phytopathogen). It is the cause of powdery mildew in the genus Doronicum. P. fusca was formerly considered synonymous with Podosphaera xanthii, but due to, mainly, the smaller ascomata and smaller oculi than P. xanthii, it was deemed a separate species. While P. xanthii remains a large species complex (with P. xanthii s.s. on Xanthium), P. fusca is now very narrowly defined.

Podosphaera plantaginis is a species of powdery mildew in the family Erysiphaceae. It is found across the world, where it affects plantains (genus Plantago).

Erysiphe platani, also known as sycamore powdery mildew, is a fungus native to North America that now infects sycamore tree species worldwide. Infections may spread rapidly in urban settings with large groups of young trees or in plant nurseries. This mildew thrives when there are high humidity conditions during the growing season. Symptomatic trees show leaf discoloration and puckering as the mildew spreads across buds and leaf surfaces. The most visible effects, which include "leaf curling, stunting, and distortion," appear on vulnerable newly emerged leaves. This infection only appears on
