In May 2003, Phytophthora ramorum S. Werres & A.W.A.M. de Cock was isolated from leaflets of wood rose (Rosa gymnocarpa Nutt.), a native, low shrub of the Rosaceae family, at the Jack London State Park in Sonoma County, California. Affected leaflets had cream-to-brown lesions or spots, sometimes delimited by a chlorotic zone. Lesions coalesced with time and spread into the petiole and rachis. Lesions on the stems were not observed.
