Lichinella nigritella (Lettau) P. Moreno & Egea

This cyanolichen has a shiny black thallus, sometimes pruinose, with lobes that are characteristically thickened at margins and usually produce isidia. It grows on exposed rocks, mainly on limestone ones but also on various calcareous silicates. The species is often found on seepage rocks. Lichinella nigritella is sparsely distributed across Europe, occurring mainly in warmer regions in the southern part of the continent. In the Czech Republic, most of its localities are known from karst areas and river valleys in central Bohemia and southern Moravia.
