It is found across Europe and North America, where it affects the genus ''Physocarpus''.
== Description == The fungus forms a chalky coating on the leaves of its host, coating and often significantly distorting leaves and stems up to whole shoots and inflorescences. It is the only species of powdery mildew on its host, and like many Erysiphaceae, only infects one genus.<ref name=":0">{{Cite book |last1=Braun |first1=Uwe |title=Taxonomic manual of the Erysiphales (powdery mildews) |last2=Cook |first2=Roger T.
