摘要： Brown spot disease caused by Colletotrichum species was found on leaves of mulberry (Morus alba L.) in Dujiangyan, Sichuan Province, China. Fungal isolates from leaf lesions were identified as six Colletotrichum species based on morphological characteristics and DNA analysis of the combined sequences ITS, GAPDH, ACT, CHS-1, TUB2, and GS. These included Colletotrichum fioriniae, C. fructicola, C. cliviae, C. karstii, C. kahawae subsp. ciggaro, and C. brevisporum. Results showed that the most important causal agent of mulberry anthracnose was C. fioriniae, causing typical brown necrotic spots or streaks, followed by C. brevisporum, C. karstii, and C. kahawae subsp. ciggaro, whereas the two other species (C. fructicola and C. cliviae) showed no pathogenicity to mulberry. This study is the first report of these species associated with mulberry in China.
