The find of a powdery mildew (Pseudoidium sp.) on Chelidonium majus in the Czech Republic and Slovakia is reported. Disease symptoms and morphological characteristics of the anamorph are described. No telemorph was observed. Morphology and distribution of the powdery mildew species on hosts of the Papaveraceae are discussed. We point out the need for phylogenetic analysis of three closely related species (Erysiphe cruciferarum, E. hylomeci, and E. macleayae) and determination of its relationship to the fungus on C. majus.
