Rhizocarpetalia geographici Klement 1950
– rhi02 Klement (1950) described the order without a taxon epithet. Although more than two Rhizocarpon species occur in the original diagnosis, the use of the taxon epithet 'geographicum' of the most common and typically occurring species became established in the licheno-sociological literature. This is, however, at variance with the requirements of the ICPN (Art. 10c). (HB).
