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,¹ but due to, mainly, the smaller ascomata and smaller oculi than P. xanthii, it was deemed a separate species.² While P. xanthii remains a large species complex (with P. xanthii s.s. on Xanthium), P. fusca is now very narrowly defined.
