摘　　要：狭壳柱孢属(Stenocarpella)中的两种菌:Stenocarpella macrospora(Earle)B.Sutton(异名:Diplodia macrospora)和Stenocarpella maydis(Berk.)B.Sutton(异名:Diplodia maydis),均可引起玉米穗腐病,其中S.maydis被认为是世界上最持久和最重要的穗腐病菌之一^([1])。S.maydis侵染玉米致使玉米茎腐病、穗腐病及叶斑病的发生,严重影响玉米产量、品级、价格等^([2])。The fungal strain 98180-8 was isolated from the maize of Malaysian containers.The pathogenicity of the isolated fungus was confirmed in inoculating tests.To elucidate the strain,morphological observation,PCR detection and ITS sequence analysis were used in this study.Taken all,the strain 98180-8 was identified as Stenocarpella maydis,an ear rot pathogen of maize.
