A group of sorediate species of a similar appearance, C. cetrarioides, C. monachorum and C. olivetorum. Morphologically they differ only in minor traits, even chemical reactions do not help to distinguish them except for C. olivetorum. The best method for their safe identification is the thin-layer chromatography. Their taxonomic status has changed over the past decades, but currently they are recognised as individual species. The revision of herbarium specimens could help to reveal their so far unclear historical distribution. Rarely, another species of Cetreria, C. chicitae occurs in central Europe and theoretically it may be found also in the Czech Republic in the future.
