The represent thousands of fungal species that are associated with diseases on a wide range of plant hosts. Understanding and stabilising the taxonomy of genera and species of is therefore of the utmost importance given their impact on agriculture, horticulture and forestry. Based on previous molecular studies, several phylogenetic and morphologically distinct genera within the have been delimited. In this study a multigene phylogenetic analysis (LSU, ITS and ) was performed based on 415 isolates representing 297 taxa and incorporating ex-type strains where available. The main aim of this study was to resolve the phylogenetic relationships among the genera currently recognised within the family, and to clarify the position of the cercosporoid fungi among them. Based on these results many well-known genera are shown to be paraphyletic, with several synapomorphic characters that have evolved more than once within the family. As a consequence, several old generic names including , , , and are resurrected, and 32 additional genera are described as new. Based on phylogenetic data 120 genera are now accepted within the family, but many currently accepted cercosporoid genera still remain unresolved pending fresh collections and DNA data. The present study provides a phylogenetic framework for future taxonomic work within the .
它们代表了数千种与多种植物寄主疾病相关的真菌物种。鉴于它们对农业、园艺和林业的影响，了解并稳定该类真菌属和种的分类学至关重要。基于之前的分子研究，已界定了该类真菌中几个系统发育和形态上不同的属。在本研究中，基于代表297个分类单元的415个分离株进行了多基因系统发育分析（LSU、ITS和[此处原文缺失具体基因名称]），并在可行的情况下纳入了模式菌株。本研究的主要目的是解析该科目前公认的属之间的系统发育关系，并阐明尾孢菌属真菌在其中的位置。基于这些结果，许多知名属被证明是并系的，有几个共衍征在该科内不止一次进化。因此，包括[此处原文缺失具体属名]、[此处原文缺失具体属名]、[此处原文缺失具体属名]、[此处原文缺失具体属名]和[此处原文缺失具体属名]在内的几个旧属名被重新启用，并描述了另外32个新属。基于系统发育数据，该科目前接受120个属，但许多目前公认的尾孢菌属真菌在有待新的采集样本和DNA数据的情况下仍未得到解决。本研究为该类真菌未来的分类学工作提供了一个系统发育框架。
