Summary In June 2016, pot‐grown Eucalyptus gunnii plants showing typical symptoms of powdery mildew disease were found in a greenhouse in Korea. Morphological characteristics of the anamorph and molecular sequence analyses of the ITS regions and 28S rDNA verified the fungus as Erysiphe alphitoides , which is known as common and widespread powdery mildew on Quercus spp. Although E. alphitoides has been reportedly associated with powdery mildew diseases of tropical trees and shrubs other than Quercus spp., this is the first finding of E. alphitoides on a Eucalyptus tree worldwide.
