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），包括其在Schizoparme（1923）中的有性形态，具有世界性分布，并与多种寄主上的叶，果实，叶，茎和根部疾病相关。这些属的物种有时作为被其他生物体感染或受到其他原因伤害的植物组织的继发入侵者而出现。在过去的几十年中发表的几项研究对Coniella，Pilidiella和Schizoparme是否存在矛盾的想法应该被视为同义词或单独的属。本研究旨在通过系统发育分析117种分离株的部分LSU nrDNA，rpb2，ITS nrDNA和tef1序列数据的串联比对，并对其形态进行系统分析。结果显示，所有菌株均聚集在单个支撑良好的进化枝中。分生孢子的颜色，传统上是科涅拉菌属和菌毛虫之间的区别特征，在整个进化枝中演化了多次，并且在裂殖藻科中不是一般的好特征。因此，这三个属应被视为同义词，与较早的名称Coniella有优先权。此外，这项研究描述了13个新物种，并为另外15个物种提出了新的组合。
