Three new species of <i>Ochrolechia</i> (Ochrolechiaceae, Pertusariales) from Guizhou Province, China.

ABSTRACT: Based on morphological, chemical and phylogenetic analyses, three species of Ochrolechia collected from Guizhou, China, are described as new to science and named Ochrolechia guizhouensis, O. kuankuoshuiensis and O. leigongshanensis. Phylogenetic trees, based on ITS and mtSSU loci, were constructed using Maximum Likelihood analysis (ML) and Bayesian Inference (BI) methods. Ochrolechia guizhouensis and O. akagiensis are positioned close to each other in the phylogenetic tree. Ochrolechia guizhouensis is morphologically characterised by its apothecia which feature rugose to rosulate, epruinose discs resembling a floral structure. Chemically, the apothecia contain gyrophoric acid, lecanoric acid and lichesterinic acid, while the thallus contains
