Four species belonging to the Lecanora subfusca group (Lecanoraceae, lichenized Ascomycotina) and containing the 2,5,7-trichloro-3-O-methyl-norlichexanthone chemosyndrome are described: L. elixii Lumbsch, L. epibryon Ach., L. mayrhoferi Lumbsch spec. nov. and L. parmelinoides Lumbsch spec. nov. The species, which are interpreted as being closely related, can be distinguished by a combination of subtle morphological and anatomical characters.
