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]
