Podosphaera xanthii is a species complex [1] of fungal plant pathogens that causes powdery mildew disease of a range of different host species. The primary symptoms are white, powder-like spots on the leaves and stems. P. xanthii sensu stricto affects plants in the genus Xanthium (cocklebur).
Some researchers formerly considered P. xanthii to be a synonym of Podosphaera fusca . [1]
