Abstract

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 hitherto 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 known. Morphological investigation of the fungus on this host shows that the specimens from Taiwan belong to another genus outside the Cystotheceae because of the lack of fibrosin bodies. Analysis of ITS rDNA sequences indicates that the anamorphic powdery mildews on camphor and orange jasmine belong to a clade representing Erysiphe quercicola, with the teleomorph known only from certain oak species (Quercus, Fagaceae), but with its anamorph known from a broad host range, particularly in the tropics.
