The first phylogeny showed this was of Bylin al. (in Biblioth. Lichenol. 96: 49–60. 2007), which constans is placed inside a monophyletic group with several species Fuscidea. These results were later confirmed by Miadlikowska Molec. Phylogen. Evol. 79: 132–168. 2014). Both these had very limited sampling, not the main aim studies. Later Zahradnikova (Taxon.
