Notes: Many molecular analyses have confirmed that the genera Podosphaera and Sphaerotheca form a clearly single monophyletic clade (Saenz & Taylor 1999, Mori et al. 2000, Takamatsu et al. 2000). Therefore, Braun and Takamatsu (2000) proposed to merge the two genera into an emended genus Podosphaera which subsequently was divided into two non-monophyletic groups, sect. Podosphaera, sect. Sphaerotheca. Section Sphaerotheca was further divided into two subsections, subsect. Sphaerotheca and subsect. Magnicellulatae. In section Podosphaera 86% of hosts and in subsection Sphaerotheca 57% of hosts belong to the Rosaceae and the close evolutionary relationship between Podosphaera and its rosaceous hosts has been revealed by Takamatsu et al. (2010).
Type species: Podosphaera myrtillina Kunze, in Kunze & Schmidt, Mykologische Hefte (Leipzig) 2: 113 (1823).
Other accepted species: Species Fungorum – search Podosphaera.
