Abstract

Through inoculation tests in the greenhouse and in the field, the previously unknown 0 and I stages of Coleosporium viburni Arth. are shown to occur on jack pine (Pinus banksiana Lamb.). These stages are described and differences in aeciospore morphology which permit distinction on pine of this rust from Coleosporium asterum (Diet.) Syd. are discussed. The description of C. asterum is amended to include differences in aeciospore size between collections on jack and red pine (Pinus resinosa Ait.). The known distribution of C. viburni is summarized.
