Podosphaera Kunze, Mykol. (Hefte) 2: 111 (1823) 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 [...]
