Information on the record of Phyllactinia moricola, a new in Ukraine alien powdery mildew fungus, is reported. The teleomorph of the fungus was collected in October–December 2020 on Morus alba in Odesa. The description and illustrations of the studied material are provided. The disease caused by this species can significantly reduce the ornamental properties of mulberry, a popular plant that is often used in greenery in the settlements of Ukraine. It is noted that the fungus can spread to Southern Europe, where it may cause significant damage to horticulture and silk production.

Keywords: adventive species, invasion, mulberry, powdery mildew, Ukraine
