Podosphaera ruborum is a species of powdery mildew in the family Erysiphaceae. It is found across Europe and North America, on plants in the genus Rubus , including multiple commercially significant crops.
The fungus forms thin, white irregular patches on the leaves of its host. Podosphaera ruborum, like most Erysiphaceae, is highly host-specific and infects only the genus Rubus . Two species in the genus ( Rubus spectabilis and Rubus ursinus ) are instead infected by the closely-related species Podosphaera rubi-spectabilis . [1]
The fungus was formally described in 1878 by Rabenhorst with the basionym Oidium ruborum. The new combination Podosphaera ruborum was created by Bradshaw and Liu in 2025. It is a member of the Podosphaera aphanis complex of species and was formally considered conspecific with that species. [1]
