Lepraria nivalis J.R. Laundon

Morphologically and chemically variable species, which requires a detailed taxonomic study. Lepraria nivalis grows on shady limestone rocks and on bryophytes that cover them. In central Europe, the species is rather rare but it may be common in regions rich in calcareous rocks. From the Czech Republic, the lichen is usually reported from single localities in karst areas. To date, three chemotypes have been found in the country: 1) containing atranorin and protocetraric acid, 2) containing atranorin and fumarprotocetraric acid and 3) containing only protocetraric acid.
