| description |
The common oak, although infrequently, can be found as urban trees in the cities of northwestern Argentina. Between late 2023 and early 2024, leaves of Quercus robur exhibiting typical symptoms of powdery mildew were collected from three provinces in this region. Based on its morphological characteristics, host specificity, and the available descriptions, the fungus was identified as Erysiphe alphitoides in the asexual phase. This represents the first report of this fungus in northwestern Argentina. The symptoms of the disease, as well as the morphological characteristics of the anamorph are described and illustrated.
