Cronartium ribicola J.C. Fischer ex Raben. 1872 (white pine blister rust)
causes a serious and lethal disease on white pines (species of the subgenus Pinus) in North America. It is also found in Europe and Asia but is not such a devastating disease in these regions. In North America, white pines have little resistance against this introduced fungus. Pines are the aecial host and Ribes species the telial host for the fungus. The planting of ornamental Ribes species is not allowed in some regions in order to reduce the risk for this disease.

Infections start at the needles and then spread to the twigs, where pale yellow blisters (aecia) break through the bark and release bright orange aeciospores. These spores infect Ribes species where they produce urediniospores (which re-infect the Ribes host) as well as teliospores and basidiospores. The latter re-infect pine trees.
