Description

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]

Taxonomy

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]
