Biogeography

Erysiphe polygoni on Rumex crispus, documented previously in California, is reported for the first time in the Pacific Northwest. Podosphaera (Sphaerotheca) fusca is reported in the Pacific Northwest for the first time on Taraxacum laevigatum, a host record documented previously in Europe. New host records for Idaho are Golovinomyces sordidus on Plantago major, Erysiphe convolvuli on Convolulus arvensus, and Podosphaera ( Sphaerotheca) aphanis on Geum macrophyllum. Golovinomyces (Erysiphe) cichoracearum on Cirsium arvense is reported for the first time in Washington.
