The disease causes considerable yield losses in many cherry growing regions. We surveyed cherry leaf spot disease in Beijing City and collected 67 fungal isolates from diseased leaves, including Alternaria species, Colletotrichum species and Didymellaceae species. Multigene phylogenetic analyses coupled with morphological observations facilitated the identification of species isolated from the diseased tissues. Pathogenicity assays were conducted for six isolates representing all the identified species and Koch?s postulates were confirmed on three cultivars of Prunus avium in a greenhouse. These results confirmed the pathogenicity on cherry leaves as symptoms were reproduced. Based on these results, Alternaria prunicola sp. nov. was concluded as the main pathogen of Cherry leaf spot in Beijing City. In addition, Alternaria alternata, Alternaria pseudoeichhorniae sp. nov., Colletotrichum aenigma, Colletotrichum pseudotheobromicola sp. nov., Epicoccum pseudokeratinophilum sp. nov., Nothophoma pruni sp. nov., Nothophoma quercina and Stagonosporopsis citrulli were isolated from the Cherry leaf spots. Significant variations in the virulence were observed among fungal species on different cherry cultivars.} }
