Podosphaera rubi-spectabilis is a species of powdery mildew in the family Erysiphaceae. It is found wherever its host plant species (Rubus spectabilis and Rubus ursinus) are, mostly in the west of North America.

Description

The fungus forms thin, white irregular patches on the leaves of its host. Podosphaera rubi-spectabilis, like most Erysiphaceae, is highly host-specific and infects only two species of Rubus. Other species in the genus are infected by the closely-related Podosphaera ruborum.

Taxonomy

The fungus was formally described in 2025 by Bradshaw and Liu. It is a member of the Podosphaera aphanis complex of species and was formally considered conspecific with that species.[1]
