On the basis of morphological and chemical data, and a phylogenetic reconstruction using six DNA regions, a new crustose,
lecanoroid lichen species from the region of Baden-Württemberg (SW Germany) is described. Myriolecis suevica
is characterized by the presence of an unexpected secondary metabolic compound, namely isousnic acid. Phylogenetic
analysis revealed that this new species is closely related to M. sambuci, the nomenclatural type for the genus Myriolecis.
‘Lecanora’ casimceana and ‘L.’ elenkinii, which resemble representatives of the genus Myriolecis also contain isousnic
acid and are therefore described in detail. The issue of replacing the generic name Myriolecis with the former name
Polyozosia for the group traditionally circumscribed as Lecanora dispersa gr. is briefly discussed.
Key words: Lichen-forming fungi, Polyozosia, Lecanora dispersa, limestone, Swabian Alb, SW Germany.
