New records for powdery mildews and Taphrina species in Idaho and Washington
- Podosphaera (Sphaerotheca) euphorbiae on Euphorbia epithymoides (= E. polychroma, cushion spurge) is reported for the first time in North America. Neoerysiphe ( Erysiphe ) galeopsidis on Lamium amplexicaule (henbit), Blumeria (Erysiphe) graminis on Festuca idahoenis (Idaho fescue), Taphrina johansonii on Populus tremuloides (trembling aspen), and Taphrina occidentalis on Alnus rubra (red alder) are reported for the first time from Idaho. Reports of Erysiphe cichoracearum on henbit may reflect misdetermined Neoerysiphe galeopsidis.
