摘　　要：从黄山市祁门县仙寓山自然保护区自然分布的多花黄精健康根茎中分离得到10株内生真菌。因未观察到分离株分生孢子及产孢结构,基于菌落特征和菌丝结构对其进行了形态学鉴定,并结合分子系统学方法,将其鉴定为新棘壳孢属5个种,其中新种3个:内生新棘壳孢Neosetophoma endophyticum,黄精新棘壳孢N.polygonatum和祁门新棘壳孢N.qimenensis;已知种2个:禾新棘壳孢N.poaceicola和贵阳新棘壳孢N.guiyangensis;棘壳孢属Setophoma已知种1个:洞穴棘壳孢Setophoma caverna。研究菌株保存于安徽农业大学昆虫病原真菌研究中心(RCEF)。Ten fungal isolates from the healthy rhizomes of Polygonatum cyrtonema naturally distributed in Xianyushan Nature Reserve of Qimen County in Anhui Province were identified based on colony and mycelial characteristics in the absence of conidia and sporogenous structures and molecular phylogenetic analysis.Five species in Neosetophoma,namely new species,N.endophyticum,N.polygonatum and N.qimenensis,and known species,N.poaceicola and N.guiyangensis were identified;besides,Setophoma caverna was also identified.The isolates were deposited in the Research Center for Entomogenous Fungi(RCEF)at Anhui Agricultural University.
