Lecanora inaurata, a corticolous member of the L. subfusca group, is described as new to science. This species is characterized by typically epruinose, reddish brown apothecial discs, a chlarotera-type epihymenium, pulicaris-type amphithecium, and chloroatranorin and zeorin as major constituents, often with accessory calycin in the thalline margins of the apothecia, imparting a distinctive yellow halo appearance when present in sufficient concentrations. Lecanora inaurata occurs in open hardwood-dominated woodlands of the Edwards Plateau and grasslands of the southern Great Plains in Oklahoma and Texas.
