Michelia odora is a rare and endangered species unique to China. In recent years, it has been discovered that this species has been suffering from leaf blight. In this study, the symptoms were observed to reveal the pathogen of M.odora leaf blight. A fungal strain Fg-1 with high pathogenicity was isolated from the diseased leaves of M.odora by conventional tissue isolation. The pathogenic strain Fg-1 was identified as Colletotrichum gloeosporioides by morphological observation and multi-gene sequence analysis of internal transcribed spacer(ITS), ribosomal large subunit(LSU), and ribosomal small subunit(SSU). The results showed that the optimum growth temperature for the pathogen was 25 ℃, and the optimal light condition was 12 h light/12 h darkness. The pathogen could grow in the potato dextrose agar with pH 4-12, with the optimal pH 7. The colonies grew on all six types of culture media tested, namely water agar, synthetic low-nutrient agar, potato sucrose agar(PSA), mung bean agar, wheat agar, and corn agar. The colonies demonstrated the best growth on PSA. The most suitable carbon source was sorbitol, and the most suitable nitrogen sources were beef extract.
