Circinaria calcarea is a species of crustose lichen in the family Megasporaceae. It was first described as a new species by Carl Linnaeus in his 1753 work Species Plantarum . Linnaeus named it Lichen calcareus, as he classified all lichens in the eponymously named genus. [2] The species has had an extensive taxonomic history, resulting in dozens of synonyms. [1] In 2010, it was placed in its current genus, Circinaria , following molecular phylogenetic analysis of the Megasporaceae. [3]
Circinaria calcarea has a cosmopolitan distribution, having been recorded from the Arctic, Asia, Australasia, Europe, Oceania, Central America, South America, and North America. It is a saxicolous lichen, and grows on calcareous, calciferous, and basic rock. [4]
