Podosphaera plantaginis

Podosphaera plantaginis is a species of powdery mildew in the family Erysiphaceae. It is found across the world, where it affects plantains.

Description

The fungus forms thin, white irregular patches on the leaves of its host. P. plantaginis infects narrow-leaved plantains such as Pl. lanceolata, which can also be infected by Golovinomyces sordidus. As a result, records on these hosts are best confirmed by microscopy, as macromorphological differences are not yet known.

Taxonomy

The fungus was formally described in 1965 by Castagne with the basionym Erysiphe ''plantaginis. The taxon was transferred to the genus Podosphaera'' by Uwe Braun and Susumu Takamatsu in 2000.
