Here, we test the current generic delimitation of (Collemataceae, Peltigerales, Ascomycota) utilizing molecular phylogeny and morphological investigations. Using DNA sequence data from the mitochondrial SSU rDNA and two nuclear protein-coding genes (MCM7 and β-tubulin) and utilizing parsimony, maximum likelihood and Bayesian phylogenetic methods, is shown to be non-monophyletic in the current sense. A new generic delimitation of is thus proposed, in which the genus is monophyletic, and three species (, , ) are excluded and transferred to other genera. is further non-monophyletic, and a more detailed investigation of species delimitations in s. str. is needed. The new combinations and are proposed.
在此，我们利用分子系统发育学和形态学研究，对（胶衣科，皮果衣目，子囊菌门）当前的通用分类界定进行了检验。通过线粒体小亚基核糖体DNA以及两个核蛋白编码基因（MCM7和β微管蛋白）的DNA序列数据，并运用简约法、最大似然法和贝叶斯系统发育方法，结果表明在当前意义上该属并非单系类群。因此，提出了一个新的该属分类界定，其中该属为单系类群，并且三个物种（，，）被排除并转移到其他属。该属进一步被证明并非单系类群，因此需要对狭义的该属物种界定进行更详细的研究。提出了新的组合和。
