Taxonomy

The lichen was first formally described as a new species by the Swedish lichenologist Erik Acharius in 1799.^[3] He classified it in the eponymous genus Lichen, which was standard at the time. In 1803 he transferred it to the genus Parmelia.^[4] Ernst Stizenberger transferred it to the genus Anzia in 1862.^[5]
