Abstract

Phylogenetic reconstructions based on ITS/5.8S and mtSSU DNA sequence data suggest a close relationship between two Lecanora species containing calycin and usnic acid and the Lecanora polytropa group. Lecanora solaris Yakovchenko & Davydov sp. nov. is described from the Altai Mountains in Russia. Its gross morphology resembles that of L. somervellii as both species have an effigurate, citrine-yellow thallus (due to the production of calycin). However, L. solaris is distinguished from L. somervellii by having a small, squamulose to marginally lobate umbilicate thallus and apothecia with a persistent margin, whereas L. somervellii has a large, distinctly placodioid thallus and an apothecial margin that is soon excluded.
