- Abstract::
- Contorted hazelnut is an ornamental tree introduced to North America from Europe. In the fall of 2004 and 2005, powdery mildew caused by Phyllactinia guttata (Wallr.:Fr.) Lév. was observed on contorted hazelnut ('contorta') located on the campus of Washington State University, Pullman, and on several C. avellana trees (unknown cultivar) on the campus of the University of Washington, Seattle. This report documents for the first time the occurrence of P. guttata on C. avellana in both eastern and western Washington.
