摘　　要：依据形态分类学和分子系统学相结合的方法对采集于大别山的子囊菌标本进行物种鉴定的结果,本研究报道了4个中国新记录种:蚤褐炭团菌Hypoxylon pulicicidum、提契诺炭团菌H.ticinense、双滴瓶头霉Phialocephala biguttulata和近木根平盘菌Rhizodiscina lignyota,基于作者所研究的标本对这4个种进行了描述及图示。在基于ITS序列和(或)LSU序列、采用贝叶斯法和最大似然法构建的系统发育树中,新记录种均得到分子数据的支持。凭证标本保存于南京师范大学真菌标本室(Herbarium of Fungi of Nanjing Normal University,HFNNU)。Identification of specimens collected from Dabie Mountains on the basis of morphological taxonomy method in combination with molecular systematics method has yielded four ascomycete species new to China,Hypoxylon pulicicidum,H.ticinense,Phialocephala biguttulata and Rhizodiscina lignyota.These species were described and illustrated based on Chinese collections.ITS and LSU(or LSU)were selected to analyze the phylogenetic relationships,and Bayesian inference and maximum likelihood analysis were used to structure phylogenetic trees.The taxonomic treatments of the four species were supported and confirmed by molecular data.Voucher specimens examined are deposited in the Herbarium of Fungi of Nanjing Normal University(HFNNU).
