摘要：
Powdery mildew diseases on Quercus (oak) trees can cause economic losses due to biomass reduction, harmful pest association and damage to street landscapes. Molecular phylogenetic studies have recognized over 20 powdery mildew species on oak worldwide. In this study, we aimed to identify the powdery mildew specimens that had been collected on Quercus species in recent years from Ottawa, Ontario through multi-gene molecular analyses and morphological assessments. Three species were recognized, including Erysiphe alphitoides, E. extensa and a new species distinct from known species. A formal taxonomic treatment and morphological and molecular characterizations for the new species, Erysiphe parmeleeana sp. nov., are provided.
