Xanthoparmelia tinctina (Maheu & A. Gillet) Hale

A thermophilic isidiate yellow-green Xanthoparmelia. It is characterized by globular to barrel-shaped isidia, black lobe underside and the presence of salazinic acid in the medulla (K+ yellow to red). It often has conspicuously wide but relatively short lobes.

The species grows on sun-exposed siliceous and other non-calcareous rocks. It is distributed from the Mediterranean, where it is common, to southern Scandinavia. In central Europe, it is quite rare and associated with the warmest areas. Xanthoparmelia tinctina is known from only a few localities in the Czech Republic; xerothermic rocks in the valleys of the Vltava river and its tributaries from Prague further downstream; and from the České středohoří hills. It is possibly overlooked and more common in the Bohemian Thermophyticum.
