Leptographium olivacea复合体包括广泛定义的Leptographium属（蛇气孔门，子囊菌门）中的物种，这些物种通常以同质分生孢子为特征。这种复合体的大多数物种都是欧洲和北美的针叶树树皮甲虫的近亲。本研究的目的是重新考虑已知种的划分，并确认最近在中国、芬兰、波兰、俄罗斯和西班牙调查中出现的几个类似L. olivacea的额外分离株的身份。对5个基因座（ACT、TUB、CAL、ITS2-LSU和TEF-1α）的序列数据进行系统发育分析，鉴定出该复合体中的14个物种。其中包括8个已知种（L. cucullatum、L. davidsonii、L. erubescens、L. francke-grosmanniae、L. olivaceapini、L. sagmatosporum和L. vescum）和6个新种（本文描述为L. breviuscapum、L. conplurium、L. pseudoalbum、L. rhizoidum、L. sylvestris和L. xiningense）。提供了空心乳酸菌、大卫乳酸菌、芥菜乳酸菌、橄榄乳酸菌、橄榄乳酸菌、sagmatosporum和泡状乳酸菌的新组合。新分型：确定了olivaceum、l.l . erubescens和l.l . sagmatosporum的分型。确定了olivaceapini和sagmatosporum的表型。除了系统发育上的分离外，同系性无性状态和具有几乎圆柱形颈部和突出的气孔菌丝的子囊，将L. olivaceum复合体与其他Leptographium复合体区分开来。
Abstract The Leptographium olivacea complex encompasses species in the broadly defined genus Leptographium (Ophiostomatales, Ascomycota) that are generally characterized by synnematous conidiophores. Most species of the complex are associates of conifer-infesting bark beetles in Europe and North America. The aims of this study were to reconsider the delineation of known species, and to confirm the identity of several additional isolates resembling L. olivacea that have emerged from recent surveys in China, Finland, Poland, Russia, and Spain. Phylogenetic analyses of sequence data for five loci (ACT, TUB, CAL, ITS2-LSU, and TEF-1α) distinguished 14 species within the complex. These included eight known species (L. cucullatum, L. davidsonii, L. erubescens, L. francke-grosmanniae, L. olivaceum, L. olivaceapini, L. sagmatosporum, and L. vescum) and six new species (herein described as L. breviuscapum, L. conplurium, L. pseudoalbum, L. rhizoidum, L. sylvestris, and L. xiningense). New combinations are provided for L. cucullatum, L. davidsonii, L. erubescens, L. olivaceum, L. olivaceapini, L. sagmatosporum and L. vescum. New Typifications: Lectotypes are designated for L. olivaceum, L. erubescens and L. sagmatosporum. Epitypes were designated for L. olivaceapini and L. sagmatosporum. In addition to phylogenetic separation, the synnematous asexual states and ascomata with almost cylindrical necks and prominent ostiolar hyphae, distinguish the L. olivaceum complex from others in Leptographium.
