Abstract

Lecanora albescens (Hoffm.) Branth & Rostr. is the correct authorship of this species, and the combination cannot be attributed to Flörke. Lecanora antiqua J. R. Laundon is described for the lichen previously, but wrongly, known in Britain as L. conferta; it is remarkable in occupying the interface between acid and calcareous surfaces on the vertical walls of medieval churches. The nomenclature of the lobed Lecanora, which has had two alternative Latin names since the early 19th century, namely L. muralis Rabenh. and L. saxicola (Pollich) Ach., has been studied and the latter was found to be correct.
