The asexual genera Coniella (1918) and Pilidiella (1927), including their sexual morphs in Schizoparme (1923), have a cosmopolitan distribution and are associated with foliar, fruit, leaf, stem and root diseases on a wide variety of hosts. Species of these genera sometimes occur as secondary invaders of plant tissues infected by other organisms or that are injured by other causes. Several studies published over the last few decades had conflicting ideas as to whether Coniella, Pilidiella and Schizoparme should be regarded as synonymous or as separate genera. The present study aims to resolve the generic classification of these genera through phylogenetic analyses of the concatenated alignment of partial LSU nrDNA, rpb2, ITS nrDNA and tef1 sequence data of 117 isolates, combined with their morphology. Results revealed that all strains cluster in a single well-supported clade. Conidial colour, traditionally the distinguishing character between Coniella and Pilidiella, evolved multiple times throughout the clade, and is not a good character at generic level in Schizoparmaceae. The three genera should therefore be regarded as synonymous, with the older name Coniella having priority. Furthermore, this study delineated 13 new species, and new combinations were proposed for a further 15 species.

无性属Coniella (1918) 和Pilidiella (1927)，包括它们在Schizoparme (1923) 中的有性变体，具有世界性分布，并与多种寄主的叶、果实、叶、茎和根病害相关。这些属的物种有时作为被其他生物体感染或因其他原因受损的植物组织的二次入侵者而出现。过去几十年发表的几项研究对于Coniella 、 Pilidiella和Schizoparme是否应被视为同义属或单独属的观点存在相互矛盾。本研究旨在通过对 117 个分离株的部分 LSU nrDNA、 rpb2 、ITS nrDNA 和tef1序列数据的串联比对及其形态进行系统发育分析，解决这些属的属属分类问题。结果显示，所有菌株都聚集在一个得到良好支持的进化枝中。分生孢子颜色传统上是Coniella和Pilidiella之间的区别特征，在整个分支中多次进化，在裂谷草科属中并不是一个好的特征。因此，这三个属应被视为同义，其中旧名Coniella优先。此外，这项研究还确定了 13 个新物种，并为另外 15 个物种提出了新组合。
