Holomorph and Phylogeny of Erysiphe chloranthi on Chloranthus japonicus in Korea

Erysiphe chloranthi is the only powdery mildew species (Erysiphaceae) found on Chloranthusplants belonging to the family Chloranthaceae. This species has long been known to bepresent in Japan and Korea and is hence regarded as endemic to East Asia. Examination ofseven Korean specimens revealed detailed morphological characteristics of the holomorphof this species. Short foot-cells of conidiophores are proposed as key characteristics thatdiffer from related species. Sequences of the internal transcribed spacer regions and largesubunit gene retrieved from four Korean samples confirm the phylogenetic position of thisspecies within the Erysiphe aquilegiae complex. These data may help elucidate the identityof this species and clarify the ambiguity of the E. aquilegiae complex. KCI Citation Count: 0
