The systematics of the ascomycete genera Apiorhynchostoma, Endoxyla and Pseudovalsaria are reevaluated based on the comparison of cultural characteristics, teleomorph morphology and DNA sequence data. Analyses of sequences of the internal transcribed spacer (ITS) of the ribosomal DNA operon and the large subunit (LSU) of the nuclear ribosomal DNA gene resolve Boliniales as a robustly supported lineage comprising Apiorhynchostoma, Camarops, Camaropella, Cornipulvina, Endoxyla and Pseudovalsaria. Within Boliniales, species of Endoxyla form a strongly supported lineage. Apiorhynchostoma curreyi and Pseudovalsaria ferruginea group with Cornipulvina ellipsoides. Species of Camarops are paraphyletic and comprise two clades, one of which includes Camaropella. Boliniaceae is emended, Endoxyla mallochii is described as new and Apiorhynchostoma trabicola is considered a synonym of Apiorhynchostoma altipetum. We also propose the combinations Endoxyla occulta, Endoxylina luteobasis and Jobellisia peckii. Keys to genera included in the Boliniaceae and to species of Apiocamarops, Apiorhynchostoma and Endoxyla are provided.
基于培养特征、有性型形态和 DNA 序列数据的比较，重新评估子囊菌属 Apiorhynchostoma、Endoxyla 和 Pseudovalsaria 的系统发育。核糖体 DNA 操纵子的内部转录间隔区（ITS）和核核糖体 DNA 基因大亚基（LSU）序列分析将 Boliniales 解析为一个强有力支持的谱系，包括 Apiorhynchostoma、Camarops、Camaropella、Cornipulvina、Endoxyla 和 Pseudovalsaria。在 Boliniales 中，Endoxyla 物种形成一个强烈支持的谱系。Apiorhynchostoma curreyi 和 Pseudovalsaria ferruginea 与 Cornipulvina ellipsoides 聚在一起。Camarops 物种是并系的，包含两个分支，其中一个分支包括 Camaropella。Boliniaceae 被修正，Endoxyla mallochii 被描述为新种，Apiorhynchostoma trabicola 被认为是 Apiorhynchostoma altipetum 的同义词。我们还提出了 Endoxyla occulta、Endoxylina luteobasis 和 Jobellisia peckii 的组合。提供了 Boliniaceae 中包含的属以及 Apiocamarops、Apiorhynchostoma 和 Endoxyla 物种的关键。
