    Abstract

    The phylogeny of the Lecanora varia group is inferred from ITS sequences using Bayesian and ML phylogenetic analysis methods. According to our data, usnic acid-containing, corticolous Lecanora species do not form a monophyletic group but occur in three major clades together with other groups of Lecanora and Protoparmeliopsis. The new combination Lecanora filamentosa (Stirt.) Elix & Palice is proposed. The new species Lecanora schizochromatica is described from northwestern North America. It produces atranorin as a major substance and is closely related to the morphologically and chemically similar L. filamentosa. The American Biatora pullula Tuck. is synonymised with Lecanora anopta Nyl., which is hereby reported for continental North America for the first time. The phylogenetic relationships between the major clades of Lecanora are still largely unresolved and require more intensive taxon and character sampling.
