First Report of Podosphaera alpina f. alpina on Tolmiea menziesii in Washington State and British Columbia

L. S. Putnicki and D. A. Glawe

August 2009


Tolmiea menziesii (Pursh) Torr. & A. Gray (Saxifragaceae, piggyback plant) is an understory species typically sold as an ornamental houseplant. We recently made several collections of T. menzii in Washington and British Columbia with powdery mildew symptoms and determined the causal agent to be Podosphaera alpina f. alpina (U. Braun) U. Braun & S. Takam. This is the first report of this fungus on T. menziesii in Washington and British Columbia.
