Phylogenetic trees, based on ITS and mtSSU loci, were constructed using Maximum Likelihood analysis (ML) and Bayesian Inference (BI) methods. <i>Ochrolechia guizhouensis</i> and <i>O. akagiensis</i> are positioned close to each other in the phylogenetic tree. <i>Ochrolechia guizhouensis</i> is morphologically characterised by its apothecia which feature rugose to rosulate, epruinose discs resembling a floral structure.

Phylogenetic analysis reveals that <i>Ochrolechia kuankuoshuiensis</i> is closely related to <i>O. parellula</i> and is distinguished by its light yellow, epruinose, deeply rugose apothecial discs, the production of gyrophoric acid and lecanoric acid and the largest ascospores known in the genus. <i>Ochrolechia leigongshanensis</i> forms an isolated phylogenetic branch which is characterised by a soraliate thallus and apothecia with a ring of smooth, salmon-pink tissue on the inner margin. The discs are epruinose to lightly pruinose and plane.
