Description

The vast majority of species in the genus Podosphaera infect hosts of the Rosaceae.^[2] Symptoms of an infection by Podosphaera species include mycelium on most often the upperside of leaves or on young shoots and twigs.

Taxonomy

The genus was formally described by Kunze in 1823. The genus Sphaerotheca was absorbed into Podosphaera in 2000 by Braun and Takamatsu. The anamorph genus of Podosphaera was Fibroidium. In 2012, due to the 'one fungus, one name' change to the Code, species from this genus were also included in Podosphaera.^[3]
