The genus Cetraria originally comprised deciduous and shrub lichen that looked quite different . The genus is cosmopolitan, but mainly found in the cold and temperate areas of the northern hemisphere. Further genera are separated from Cetraria . So were about Schneeflechte (formerly C. nivalis ) and the Kapuzenflechte (formerly C. cucullata ) in the newly created genus flavocetraria moved. Cetraria in the narrow sense then comprises only about 15 species. There are 5 species in Central Europe: Cetraria aculeata, ericetorum, islandica, muricata and sepincola. An extract is obtained from the thallus of Cetraria islandica that has an expectorant effect and is used, for example, in cough drops.
The name Cetraria comes from the Latin word caetra = small, light leather shield and refers to the fact that the storage sections of the Icelandic moss are often shiny brown.
