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]
