Xanthoparmelia loxodes (Nyl.) O. Blanco & al.

One of the pair of isidiate brown Xanthoparmelia species present in the Czech Republic. It is distinguished from X. verruculifera by a paler and larger thallus, larger isidia and the presence of glomelliferic, glomellic and perlatolic acids and traces of other substances. Thus, it is chemically identical to non-isidiate X. delisei.

The species grows on siliceous and extrusive rocks, including those with basic pH. It occurs on open sun-exposed rocks and stones, but also anthropogenic substrates and eutrophicated sites. In the Czech Republic, it is quite abundant from the lowlands to the mountains, with the centre of distribution at lower elevations. In Europe, it is a common species in the temperate zone, with a suboceanic preference.
