Podosphaera ferruginea is a species of powdery mildew in the family Erysiphaceae. It is found across Eurasia and North America, where it affects burnets (genus Sanguisorba ).

Description

The fungus forms thin, white irregular patches on the leaves of its host. P.ferruginea, like most Erysiphaceae, is highly host-specific and infects only the genus Sanguisorba . ^[1]

Taxonomy

The fungus was formally described in 1819 by Schlechtendal with the basionym Alphitomorpha ferruginea. The taxon was transferred to the genus Podosphaera by Uwe Braun and Susumu Takamatsu in 2000. ^[2]
