• Pseudoidium cinnamomi on Cinnamomum camphora is found to be the anamorph of Erysiphe quercicola.
• A fungus reported as Oidium murrayae on Murraya paniculata in Taiwan is the anamorph of Erysiphe quercicola.
• Cinnamomum (Lauraceae) and Murraya (Rutaceae) are new host genera for Erysiphe quercicola.
Based on collections of powdery mildews (Erysiphales) in Taiwan and combined molecular and morphological analyses, camphor tree (Cinnamomum camphora) and orange jasmine (Murraya paniculata) are recognized as new hosts of the anamorph of the powdery mildew Erysiphe quercicola. The anamorphic powdery mildew on C. camphora has been known as Pseudoidium cinnamomi, but its relationship to a teleomorph was unknown. For M. paniculata as substrate of powdery mildew, only an anamorphic Cystotheca species has been named. Morphological investigation of the fungus on this host shows that the specimens from Taiwan belong to another genus because of the lack of fibrosin bodies. Analysis of internal transcribed spacer sequences indicates that the anamorphic powdery mildews on camphor and orange jasmine belong to a clade representing E. quercicola, with the teleomorph found only on oak species (Quercus, Fagaceae), but with its anamorph reported from a broad host range, particularly in the tropics.
