摘　　要：对nrDNA大亚基部分序列进行序列分析,探讨丛赤壳科11个属的属间关系。研究结果表明,Cosmospora不是单起源,它的成员分别与Nectria,Haematonectria以及Neocosmospora3个不同的属聚类在一起;Haematonectria和Neocosmospora的亲缘关系最接近;Lanatonectria为一个独立的属;以Neonectriadiscophoravar.discophora为代表的Neonectria是一个可靠的属。Phylogenefic relationships among 11 genera in the family Nectriaceae, Hypocreales were studied by using analysis of partial sequences of the nuclear large subunit rDNA. The results showed that Cosmospora is possibly not monophyletic, species of the genus tested showed close relationships to 3 different genera i.e. Nectria, Haematonectria, and Neocosmospora; species of Haematonectria and Neocosmospora are very closely related; Lanatonectria is a tenable genus; and Neonectria represented by N. discophora var. discophora is distinct at the generic level.
