Phlebia属长期以来被认为是一个多系或并系的分类单元，包括不同的组更密切相关的物种。因此，该属的划分被赋予了不同的解释，并由不同的作者提出了几个重新排列。本研究获得了20种脉虫的25S rDNA序列，并进行了系统发育分析。由于该属的推测并系性，不同的外类群被用于不同的分类群。一个核心的物种群，包括模式Ph. radiata，是很好的区别。然而，对于属的划界，提出了一个更弱支持的分支的更广泛的范围。该分支还包括Phlebiopsis lactea，并重申了其在Phlebia中的组合。两个种，Ph.griseoflavescens和Ph.tristis，明显地从这个分支中分离出来，应该从该属中删除。形态学特征被用于一个单独的系统发育分析，但结果不符合从序列数据的分析。
The genus Phlebia has long been regarded as a polyphyletic or paraphyletic taxon, including distinct groups of more closely related species. Consequently, the delimitation of the genus has been given different interpretations and several rearrangements have been proposed by various authors. In the present study, DNA sequences (25S, rDNA) were obtained for twenty species of the genus Phlebia and a phylogenetic analysis was performed. Because of the presumably paraphyletic nature of the genus, different outgroups were used for different sets of taxa. A core group of species, including the type Ph. radiata, is well distinguished. For the delimitation of the genus, however, the wider scope of a more weakly supported clade is proposed. This clade also includes Phlebiopsis gigantea and its combination in Phlebia is reaffirmed. Two species, Ph. griseoflavescens and Ph. tristis, are distinctly separated from this clade and should be removed from the genus. Morphological characters were used in a separate phylogenetic analysis but the result did not conform with analysis from sequence data.
