【摘要】对Corallomycetella属的概念进行了阐述,该属包括子实体为红色、在自然和培养条件下产生菌索的丛赤壳类真菌。根据对近期采集的标本的观察和多基因系统树分析的结果,广义的Corallomycetella repens形成2个分支,它们与生物地理因素相关联。狭义的Corallomycetella repens限于来自亚洲的标本,而C.elegans来自非洲和美洲。Corallomycetella属成熟的子囊孢子表面具有纤细条纹,此特征过去曾被忽略,C.jatrophae与广义的Neonectria属关系接近,而与C.repens和C.elegans关系较远;因而建立新属Corallonectria,其子囊壳表面细粉状,无性型为束丝结构并与镰孢菌相似。
