本文对Dactylella、变形球孢科（Ascomycetes）及相关属Vermispora进行了系统研究，并根据形态学和ITS 1 -5. 8 S-ITS 2 rDNA序列的系统发育分析对它们进行了订正。39株以前分配到Dactylella和Vermispora，包括28个从Centraalbureau voor Schimmelcultures和11个从我们的实验室进行了研究。基于ITS序列比对，所有测试菌株聚类成三个单系统发生分支对应于三个属，例如Dactylella，Vermispora和一个独特的组，包括具有非常短的分生孢子梗的物种。修订了Dactylella和Vermispora的分类界限，并介绍了一个新属Brachyphoris。
Dactylella, anamorphic Orbiliaceae (Ascomycetes) and related genus Vermispora are systematically studied and are revised according to morphology and phylogenetic analyses of ITS1-5.8S-ITS2 rDNA sequences. Thirty-nine isolates formerly assigned to Dactylella and Vermispora, including 28 from the Centraalbureau voor Schimmelcultures and 11 from our laboratory were studied. Based on ITS sequence alignment, all the tested strains cluster into three monophylogenic clades corresponding to three genera, e.g. Dactylella, Vermispora and a distinct group comprising species with very short conidiophores. The circumscription of Dactylella and Vermispora are emended and a new genus Brachyphoris is introduced.
