Geniculodendron pyriforme, the imperfect state of Caloscypha fulgens, caused mortality of Engelmann and Sitka spruce in Oregon and Washington. This fungus killed 0.44.8% of the seeds in 13.4% of the seed lots. Twenty-one genera of fungi were isolated from samples of 67 seed lots, and most of these also caused seed mortality under laboratory conditions.
