通过比较与北美山毛榉树皮溃疡病相关的两种新丛赤壳菌属的分离株和另外的新丛赤壳菌属（Neonectria coccobacterium）的分离株，评价了这两种新丛赤壳菌属之间的关系。Fr.）在法古斯身上发现的罗斯曼和塞缪尔小组。对翻译延伸因子1-α（EF 1-α）、RNA聚合酶II第二大亚基（RPB 2）和β-微管蛋白中的基因区域进行测序和分析。结果表明，真菌与山毛榉树皮病以前被称为新丛赤壳变种。faginata Lohman等（相当于Nectria coccobalus（.：Fr.）Fr. var. faginata Lohman等人）应被视为一个独立的物种，新丛赤霉faginata，有别于新丛赤霉coccidae。Neonectria faginata，包括其变态状态，学名为Neonectria faginatum C.aBooth，仅在北美的水青冈上发现。在北美与山毛榉树皮病相关的第二个物种是Neonectria ditissima（Tul. & C. aTul.）Samuels & Rossman，其可基于子囊孢子大小、分生孢子大小和形状以及菌落着色在形态上与新赤壳菌区分。形态学和分子数据表明，Neonectria ditissima代表了Neonectria galligena Bres的旧名称。类似地，Neonectria ditissima的变形状态是更古老的加词Escherichrocarpon heteronema，而Escherichrocarpon willkommii是同义词。Neonectria ditissima发生在北美和欧洲的各种硬木树上。新赤壳菌仅在欧洲的水青冈上发生。大叶新丛赤壳Neonectria major（Wollenw.）卡斯特& Rossman被认为是只在加拿大（不列颠哥伦比亚省）、法国、挪威和美国（华盛顿）的赤杨属上出现的物种。以下命名的变化建议：Neonectria faginata comb. and stat.十一月，新丛赤壳Neonectria fuckeliana comb. nov常春藤新丛枝菌。nov.，大新丛赤壳菌梳理和统计十一月，和紫红新丛赤壳Neonectria punicea comb. nov.
The relationship of two species of Neonectria associated with beech bark canker in North America was evaluated by comparing isolates of these and additional species of the Neonectria coccinea (Pers.:Fr.) Rossman & Samuels group found on Fagus. Gene regions in the translation elongation factor 1-alpha (EF1-alpha), RNA polymerase II second largest subunit (RPB2), and beta-tubulin were sequenced and analyzed. Results indicate that the fungus associated with beech bark disease previously known as Neonectria coccinea var. faginata Lohman et al. (equivalent to Nectria coccinea (Pers.:Fr.) Fr. var. faginata Lohman et al.) should be recognized as a separate species, Neonectria faginata, distinct from Neonectria coccinea. Neonectria faginata including its anamorphic state, Cylindrocarpon faginatum C.aBooth, is known only on Fagus in North America. A second species associated with beech bark disease in North America is Neonectria ditissima (Tul. & C.aTul.) Samuels & Rossman, which can be distinguished morphologically from Neonectria faginata based on ascospore size, conidial size and shape, and colony pigmentation. Morphological and molecular data indicate that Neonectria ditissima represents an older name for Neonectria galligena Bres. Similarly, the anamorphic state of Neonectria ditissima is the older epithet Cylindrocarpon heteronema with Cylindrocarpon willkommii as a synonym. Neonectria ditissima occurs on a variety of hardwood trees in North America and Europe. Neonectria coccinea occurs only on Fagus in Europe. Neonectria major (Wollenw.) Castl. & Rossman is recognized as a species that occurs only on Alnus in Canada (British Columbia), France, Norway, and the United States (Washington). The following nomenclatural changes are proposed: Neonectria faginata comb. and stat. nov., Neonectria fuckeliana comb. nov., Neonectria hederae comb. nov., Neonectria major comb. and stat. nov., and Neonectria punicea comb. nov.
