For comparison, X. calcicola was also included in the study. Morphological as well as molecular data were utilized. Morphology indicated the presence of three species, Xanthoria parietina, X. calcicola, and X. aureola, the latter of which is resurrected here from synonymy. The most important separating characters involve colour and thickness of the thallus, lobe width, morphology of laminar structures, and the texture of the upper surface. X. aureola, as recognized here, mostly occurs on seashore rocks. Part of the IGS region as well as the complete ITS were sequenced in 70 individual thalli representing ten geographical regions in Europe. In total, 19 different IGS haplotypes and 20 different ITS haplotypes were present in the data set. Owing to indications of possible recombination between the IGS and the ITS, the two data sets were analyzed separately. Haplotype networks were estimated, both of which indicate that X. parietina is distinct from X. aureola and X. calcicola. In our sample, the two latter do not share haplotypes, but are only separated by a few mutational steps.</p>

Phylogenetic reconstructions were performed using Bayesian MCMC tree sampling and a maximum likelihood approach. The Micareaceae in its current sense is highly heterogeneous, and Helocarpon, Psilolechia, and Scutula, all thought to be close relatives of Micarea, are shown to be only distantly related. The genus Micarea is paraphyletic unless the entire Pilocarpaceae and Ectolechiaceae are included, as also indicated by an expected likelihood weights test. It is suggested that the Micareaceae is reduced to synonymy with the Pilocarpaceae, which also includes the Ectolechiaceae, and that Micarea may have to be divided into a series of smaller genera in the future. Micarea species with a &#39;non-micareoid&#39; photobiont group with Psora and the Ramalinaceae, whereas Micarea intrusa appears to belong in Scoliciosporum. Three species fall inside the paraphyletic Micarea: Szczawinskia tsugae, Catillaria contristans, and Fellhaneropsis vezdae. Tropical foliicolous taxa are nested within groups of mainly temperate and arctic-alpine distribution. A &#39;micareoid&#39; photobiont appears to be plesiomorphic in the Pilocarpaceae but has been lost a few times.</p>
