The phylogeny of Agyriaceae was investigated using MP and Bayesian approaches based on a combined dataset of nuLSU rDNA, mtSSU rDNA, and RPB1 sequences of 78 ascomycetes. The type genus of the family is shown to be a strongly supported sister to Coccotremataceae+Pertusariaceae, whereas the remaining species currently classified in Agyriaceae have a well-supported sister-group relationship with Baeomycetales. Monophyly of Agyriaceae is significantly rejected using two independent alternative topology tests. The micromorphology in Agyriaceae s. lat., Coccotremataceae, and Pertusariaceae is restudied. It is confirmed that the ascus type of Agyrium agrees with that of other taxa currently placed in Agyriaceae, and hence the ascus type is interpreted as homoplasious and phylogenetically misleading in this group of fungi. Consequently, we suggest that Trapeliaceae be resurrected for the lichenized taxa currently classified in Agyriaceae, and that this family be placed in Baeomycetales. The ordinal classification in Ostropomycetidae, especially the circumscription of Pertusariales and its distinction from Agyriales, requires additional studies.
基于78种子囊菌的核大核糖体亚基（nuLSU）rDNA、线粒体小核糖体亚基（mtSSU）rDNA和RNA聚合酶II最大亚基（RPB1）序列的组合数据集，采用最大简约法（MP）和贝叶斯方法对粉衣科的系统发育进行了研究。结果表明，该科的模式属是与球腔菌科+黑盘衣科形成强支持的姐妹类群，而目前归入粉衣科的其余物种与粉盘菌目有良好支持的姐妹群关系。使用两个独立的替代拓扑检验，显著拒绝了粉衣科的单系性。对广义粉衣科、球腔菌科和黑盘衣科的微观形态进行了重新研究。证实了粉衣属的子囊类型与目前归入粉衣科的其他类群一致，因此在这组真菌中，子囊类型被解释为同形的且在系统发育上具有误导性。因此，我们建议恢复陷阱衣科，用于目前归入粉衣科的地衣类群，并将该科置于粉盘菌目中。对星裂盘菌亚纲的目级分类，特别是黑盘衣目的界定及其与粉衣目的区分，需要进一步研究。
