Roccellaria
''Roccellina'' is a genus of lichen-forming fungi in the family Roccellaceae. Taxonomy The genus was circumscribed in 1898 by British botanist Otto Vernon Darbishire with ''Roccellina condensata'' as the type, and at that time, only species. A year earlier, Darbishire published the genus ''Roccellaria'' to contain the species ''Roccellaria intricata''. More than a century later, molecular phylogenetic analysis showed that this species is nested in the polyphyletic genus ''Roccellina''. Because ''Roccellaria'' was published earlier than ''Roccellina'', the name ''Roccellaria'' has priority, threatening to disrupt the nomenclature of all the ''Roccellina'' species. To avoid this nomenclatural instability, Swedish botanist Anders Tehler made a proposal to formally conserve the name ''Roccellina'' over ''Roccellaria''; the proposal was later accepted by the Nomenclature Committee for Fungi in 2010.

Roccellina Arboricola
''Roccellina'' is a genus of lichen-forming fungi in the family Roccellaceae. Taxonomy The genus was circumscribed in 1898 by British botanist Otto Vernon Darbishire with '' Roccellina condensata'' as the type, and at that time, only species. A year earlier, Darbishire published the genus ''Roccellaria'' to contain the species ''Roccellaria intricata''. More than a century later, molecular phylogenetic Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to ... analysis showed that this species is nested in the polyphyletic genus ''Roccellina''.

Lichen Genera
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches ( fruticose); flat leaf-like structures ( foliose); grow crust ...
