Podosphaera is a genus of obligate biotrophic fungi in the family Erysiphaceae.^[2] Species in this genus are plant pathogens, causing powdery mildew, notably on hops and cucurbits.

The section Podosphaera (formerly the genus Podosphaera) parasitizes woody plants, and about 90 % of its hosts belong to the Rosaceae.^[3] The section Sphaerotheca (formerly the genus Sphaerotheca) is further divided into the subsections Sphaerotheca and Magnicellulatae.^[3] Over 50% of the hosts of the former belong to the Rosaceae, whereas hosts of the Magnicellulatae are scattered among 40 plant families but not the Rosaceae.^[3] In 2010 Takamatsu et al used ITS sequences and 28S rDNA to divide the genus into two, with clade 1 consisting of Podosphaera tridactyla (section Podosphaera) on Prunus spp. and subsection Magnicellulatae, and clade 2 consisting of the remainder of section Podosphaera and section Sphaerotheca.^[3]

P. macularis is an economically important pathogen of hops; isolate HPM-609 was sequenced in 2023 and has a genome of 102.28Mbp with 6,954 genes.^[4]
