Zhao, (1981) Sphaerotheca erigerontis-canadensis (Lév.)

& Shirai, (1900) Podosphaera fusca is a fungus that parasitically infects plants (a phytopathogen).

It is one cause of powdery mildew in melons and gourds.

[1] Some sources suggest that P. fusca should be considered synonymous with P. xanthii,[1] while others maintain they are separate species in the subsection Magnicellulata of the section Sphaerotheca of the genus Podosphaera, as of 2011[update], based on the size of chasmothecia, and on the thin-walled portion of the asci (oculus).
