为了给防治大果紫檀叶斑病提供理论依据，对发生于广东大果紫檀上的一种新病害--叶斑病的病原进行了形态学及分子生物学鉴定。通过观察病害症状，分离培养病原菌并观察菌落形态、产孢结构及分生孢子特征，并结合病菌DNA序列对比，最后将其鉴定为间座壳属真菌，其无性阶段为拟茎点霉属。

To provide theoretical basis for controlling leaf sopt disease of Pterocarpus macrocarpus, the pathogen of leaf spot disease was identified in terms of morphology and molecular biology. Through observing disease symptoms, seperating culture of pathogen, and observing colonial morphology, conidial fructiifcation and conidial features, and comparing pathogen DNA sequence, it ifnally was identiifed as Diaporthe fungus, and its asexual stage belonged to Phomopsis.
