Two Erysiphe species, E. diervillae and E. weigelae, were recognized powdery mildew pathogens infecting Weigela species in East Asia, with E. weigelae first documented in Korea in the early 2000s. Based on a recent taxonomic revision, E. weigelae was synonymyzed with E. diervillae var. weigelae. To update our knowledge on this fungus, the holomorph morphology of the Korean powdery mildew on Weigela was described by integrating detailed morphological characterization and molecular phylogenetic studies. The newly generated sequences of the internal transcribed spacer regions and large subunit gene of rDNA have been submitted to GenBank. This study provides the first molecular phylogeny report of E. diervillae.
