Relicina is a genus of foliose lichens belonging to the large family Parmeliaceae. It contains 59 species.

Taxonomy

Relicina was originally conceived as a series of the large genus Parmelia by lichenologists Mason Hale and Syo Kurokawa in 1964. A decade later, they promoted it to the status of genus. The genus Relicinopsis, proposed by Australian lichenologists John Elix and Doug Verdon in 1986 as a segregate of Pseudoparmelia, was shown to be nested within Relicina in a 2017 molecular phylogenetics study.
