摘　　要：In 2014, a disease of black spot was found on leaves of Avicennia marina （ one of the mangroves） inDonghai island of Zhanjiang, Guangdong Province. By the method of pathogen-containing tissue isolation andpathogenicity test, we obtained a pathogenic isolate bgrl. Based on morphological characteristics and sequence a^nalysis of rDNA-1TS and glyceraldehyde-3-phosphate dehydrogenase （gpd） gene, the isolate was identified asStemphylium lycopersici. This is the first report of leaf black spot on Avicennia marina in China.In 2014, a disease of black spot was found on leaves of Avicennia marina （ one of the mangroves） in Donghai island of Zhanjiang, Guangdong Province.
