Abstract
The dwarf mistletoe severely parasitizing Pacific silver fir in Oregon is described as a new subspecies of hemlock dwarf mistletoe. This classification is based on morphological and host range differences between hemlock dwarf mistletoe, Arceuthobium tsugense (Rosendahl) G. N. Jones subsp. tsugense, and the new subspecies, Pacific silver fir dwarf mistletoe, Arceuthobium tsugense subsp. amabilae Mathiasen & C. Daugherty. The new subspecies is parasitic principally on Abies amabilis, A. procera, and Tsuga mertensiana (Bongard) Carrière. Secondarily parasitic on A. lasiocarpa, occasionally parasitic on T. heterophylla and A. lowiana (Gordon) A. Murray, and rarely parasitic on A. grandis and Pinus monticola Douglas ex D. Don.
