    In the course of routine examinations of powdery mildews collected in Idaho and Oregon, USA, some of the identified species proved to be new to North America, in some cases on new host plants. Leveillula papilionacearum and L. picridis are first records from the USA. Astragalus filipes, Dalea ornata and D. searlsiae are new hosts for Leveillula papilionacearum. Enceliopsis, Heliomeris and Machaeranthera are new host genera for L. picridis. Additional records refer to powdery mildew species which have been rarely reported from North America or first records on certain hosts.
