Lecanora inaurata, a new member of theL. subfuscagroup from central North America

Abstract

AbstractLecanora inaurata, a corticolous member of theL.subfuscagroup, is described as new to science. This species is characterized by typically epruinose, reddish brown apothecial discs, achlarotera-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 inaurataoccurs in open hardwood-dominated woodlands of the Edwards Plateau and grasslands of the southern Great Plains in Oklahoma and Texas.
