The ascomycete order Diaporthales includes a number of plant pathogenic fungi such as Cryphonectria parasitica, the chestnut blight fungus, as well as many asexually reproducing fungi without known sexual states. Relationships among genera in the Diaporthales were evaluated as a basis for the recognition of families and to provide a taxonomic framework for the asexually reproducing diaporthalean fungi. Phylogenetic relationships were determined based on analyses of large subunit (LSU) nuclear ribosomal DNA (nrDNA) sequences. Within the Diaporthales 82 sequences representing 69 taxa were analyzed. Results suggest the presence of at least six major lineages within the Diaporthales recognized as the Gnomoniaceae sensu stricto, Melanconidaceae sensu stricto, Schizoparme complex including the anamorph genera Coniella and Pilidiella, Cryphonectria-Endothia complex, Valsaceae sensu stricto, and Diaporthaceae sensu stricto. In addition, six teleomorphic and anamorphic taxa fell within the Diaporthales but were not allied with any of the six lineages.
散囊菌目包括一些植物病原菌，如栗疫菌，栗疫病真菌，以及许多无性繁殖真菌，没有已知的有性状态。散囊菌目的属之间的关系被评估为识别科的基础，并为无性繁殖的散囊菌目真菌提供一个分类框架。系统发育关系是基于大亚基（LSU）核核糖体 DNA（nrDNA）序列分析确定的。在散囊菌目中，分析了代表 69 个分类群的 82 个序列。结果表明，在散囊菌目中至少存在六个主要谱系，被认为是狭义的丛梗孢科、狭义的黑盘孢科、包括无性型属 Coniella 和 Pilidiella 的 Schizoparme 复合体、Cryphonectria-Endothia 复合体、狭义的 Valsaceae 和狭义的 Diaporthaceae。此外，六个有性型和无性型分类群属于散囊菌目，但与六个谱系中的任何一个都没有联系。
