Xanthoparmelia protomatrae (Gyeln.) Hale

A thermophilic non-isidiate yellow-green Xanthoparmelia. From similar species, it is distinguished by the brown lobe underside and the presence of fumarprotocetraric acid in the medulla (K+ brown, Pd+ red). In the field, it is difficult to distinguish from the commonly co-occuring X. stenophylla.

In Europe, it is mainly found in the west and central parts of the continent. In the Czech Republic, the species is scattered to locally abundant on sun-exposed acidic siliceous and extrusive rock in warmer areas, typically river valleys, e.g., the Vltava, Berounka or Dyje rivers. Most of its localities are in central Bohemia.
