The brown felt blight fungus (Herpotrichia juniperi) was found colonizing shoots of dwarf mistletoe (Arceuthobium abietinum f. sp. magnificae) growing on Abies magnificae in the higher elevations of the southern Cascades in California. The fungus was found only where deep snowpacks persist for a long time. Except for this report and one on Primula sp., the fungus is known to colonize only coniferous species.
