Abstract

Abnormal symptoms were observed on Anemone flaccida in Korea, indicating an infection caused by smut fungi. Morphological and molecular analyses of the strain KNUF-UB were consistent with previous reports of Urocystis eranthidis. Therefore, this is the first report of smut caused by U. eranthidis on A. flaccida in Korea.
