文章摘要：

: A new disease was observed on jujube (Ziziphus jujuba Mill.) in Awti county, Xinjiang, China, in 2014. The symptoms on infected leaves consisted of spots which were tan in the centre, with black pycnidia, surrounded by dark-brown to black margins, and yellow halos. Infected fruit became dark brown to black, and were covered by small pycnidia. The causal agent was isolated from infected leaves and fruit. Pathogenicity tests showed that the fungus could infect jujube fruits, which developed the same symptoms under artificial inoculation conditions as those observed in the field. The fungus was identified based on morphological and cultural characteristics as Nothophoma quercina (Syd) Q. Chen
