Alder rust, Melampsoridium hiratsukanum Ito, identified from Wales, UK and British Columbia, Canada
Forest Pathology 42 (4), 348-350
Abstract: An epidemic rust, Melampsoridium hiratsukanum, originating from East Asia has spread to Europe over the last two decades. We report the first observation of this rust in the British Isles on leaves of Alnus incana and A. glutinosa. In addition to M. hiratsukanum, a native M. betulinum-like rust co-occurred on the same leaves as a mixed infection. We also confirm that a rust on A. rubra in Western Canada is identical to M. hiratsukanum present in East Asia and Europe.
