根据形态和分子资料，在P. sulcata复合体中将barrenoae描述为新种。新种表面上类似于P. sulcata，但不同之处在于具有简单的根茎，而该复合体的其他物种具有方玫瑰根茎。核ITS rDNA和部分β -微管蛋白基因序列已被用作分子标记。在系统发育分析中，P. sulcata可分为4个支系，其中一个支系对应于本文所描述的新分类单元的形态型。来自伊比利亚半岛不同地点的6个新分类单元样本形成了一个强有力的单系群。
Parmelia barrenoae is described as new to science in the P. sulcata complex on the basis of morphological and molecular data. The new species is superficially similar to P. sulcata but differs in having simple rhizines whereas the other species of the complex have squarrose rhizines. Nuclear ITS rDNA and partial beta-tubulin gene sequences have been used as molecular markers. In the phylogenetic analysis, P. sulcata falls into four well supported clades, one of them corresponds to the morphotype that is described here as a new taxon. Six samples of the new taxon from different locations on the Iberian Peninsula form a strongly supported monophyletic group.
