线粒体小亚基（mtSSU）rDNA序列分析揭示了新丛赤壳属植物的系统发育关系。（anamorphs = Aidrocarpon Wollenw.;子囊菌纲，肉座菌目）。12株代表7种在5个分类非正式组的新丛赤壳属进行了系统发育分析。内弯镰孢菌施奈德（有性型：赤霉属）和朱砂叶赤壳（Nectria cinnabarina（Fr.）Fr.（=丛赤壳属）是外群体所有的Neonectria物种形成了一个强有力的支持分支相对于外类群，表明一个单一的子囊菌属的全形的drocarpon。在Neonectria分支有三个很好的支持，只有部分对应的表型定义的组的亚分支。12个新丛赤霉属分离物之间的DNA序列差异为2.3- 7.4%，足以解决它们。结果表明，mtSSU rDNA序列适合于新丛赤霉属和刺果霉属的系统发育分析。以下新组合被提出：Neonectria...
Mitochondrial small subunit (mtSSU) rDNA sequences elucidated phylogenetic relationships in Neonectria Wollenw. (anamorphs = Cylindrocarpon Wollenw.; Ascomycetes, Hypocreales). Twelve isolates representing seven species in five taxonomically informal groups of Neonectria were subjected to phylogenetic analysis. Fusarium inflexum R. Schneid. (teleomorph: Gibberella) and Nectria cinnabarina (Fr.) Fr. (= Nectria s.str.) were outgroups. All of the Neonectria species formed a strongly supported clade with respect to the outgroups, indicating a single ascomycete genus for the holomorphs of Cylindrocarpon. Within the Neonectria clade there were three well-supported subclades that only partially corresponded to phenotype-defined groups. DNA sequence divergence among the twelve Neonectria isolates, 2.3-7.4%, was sufficient to resolve them. The results suggest that the mtSSU rDNA region is appropriate for phylogenetic analysis of Neonectria and Cylindrocarpon. The following new combinations are proposed: Neonectria...
