Aspen Bibliography
Four aspen stands with greater than 90% sprout mortality in Colorado and one in Arizona were evaluated for fungal pathogens. There 4- to 5-year-old sprouts had rapidly expanding cankers moving from the terminal to the ground line. Roots of sampled sprouts showed no damage and root diseases were not found. Fruiting structures of Cytospora chrysosperma were consistently found on dying stems, while those of Dothiora polyspora were occasionally found. The same organisms were isolated from the margins of advancing cankers. Pathogenicity tests using greenhouse-grown aspen trees indicated C. chrysosperma caused rapidly expanding cankers similar to those observed on the aspen …
