Stored seeds were assayed for the seed-borne fungus Caloscyphafulgens and the pathogen was found in 0, 25, 3, 0, 0, 0, 29, 16, 14, 0, and 0% of the seed lots of Abiesamabilis, A. grandis, Pseudotsugamenziesii, Pinusponderosa, P. monticola, P. contorta, Piceaglauca, P. engelmannii, P. glauca × P. engelmannii hybrid, Tsugamertensiana, and T. heterophylla, respectively. Within infested seed lots, 0.4 to 22.4% of the seeds were infected. There was no relationship between incidence of infested seed lots and year of cone collection or geographic origin. Overall, squirrel-cache collected cones, especially of Picea spp., had the highest incidence, and slash-picked cones the lowest incidence, of C. fulgens infested seed lots. The percentage of diseased seeds, within infested seed lots, was unrelated to the origin of ground-picked cones.
