Roccellina is a genus of lichen-forming fungi in the family Roccellaceae. [2]
The genus was circumscribed in 1898 by British botanist Otto Vernon Darbishire with Roccellina condensata as the type. At that time, only species. [3] 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; [4] the proposal was later accepted by the Nomenclature Committee for Fungi in 2010.

Chrysotrichaceae is a family of lichenized fungi in the order Arthoniales. Member of this family have a widespread distribution, but are especially prevalent in tropical areas. "Chrysothrichaceae" and "Chrysothricaceae" are alternative spellings that have been used in some older publications; the latter was used by Alexander Zahlbruckner in the protologue publication. Both of these spellings are considered incorrect, and the current spelling has been formalised following a proposal for conservation of Chrysotrichaceae against Pulverariaceae.
The Roccellaceae are a family of mostly lichen-forming fungi in the order Arthoniales, circumscribed by the French botanist François Fulgis Chevallier in 1826. Species in the family exhibit various growth forms, including crustose and fruticose thalli, and diverse reproductive structures. Roccellaceae species typically have apotheciate or lirellate ascomata, often with distinct blackened margins. Molecular phylogenetics studies have revealed significant genetic diversity and complex evolutionary histories within the family.
Gymnographopsis is a genus of lichen-forming fungi in the family Redonographaceae.
Fuscopannaria is a genus of lichen-forming fungi in the family Pannariaceae. It has 55 species.
Dendrographa is a genus of lichen-forming fungi in the family Roccellaceae. It has seven species. It was given its current name by Otto Vernon Darbishire in 1895.
Pentagenella is a genus of lichen-forming fungi in the family Opegraphaceae. It contains five species.
Lecanactis is a genus of crustose lichens, commonly called old wood rimmed lichen. The genus was circumscribed in 1855 by German lichenologist Gustav Wilhelm Körber, who assigned Lecanactis abietina as the type species.
Ingaderia is a genus of lichen-forming fungi in the family Opegraphaceae. The genus was circumscribed by British botanist Otto Vernon Darbishire in 1897.
Roccella is a genus of 23 species of lichens in the family Roccellaceae. The genus was circumscribed by Swiss botanist Augustin Pyramus de Candolle in 1805, with Roccella fuciformis as the type species.
Roccellographa is a genus of lichen-forming fungi in the family Roccellographaceae. The genus was circumscribed by Austrian lichenologist Julius Steiner in 1902, with Roccellographa cretacea assigned as the type, and at that time, the only species. Three additional species have since been transferred to the genus from other genera.
Sigridea is a genus of lichenized fungi in the family Roccellaceae.
Leptogium is a genus of lichen-forming fungi in the family Collemataceae. It has about 110 species. Species formerly classified under Leptogium have since been divided among the genera Leptogium, Pseudoleptogium, and Scytinium. Leptogium lichens are predominantly found on tree bark or soil, often among mosses, and sometimes on rocks in moist environments.
Chrysothrix is a genus of lichen-forming fungi in the family Chrysotrichaceae. They are commonly called gold dust lichens or sulfur dust lichens, because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia. Apothecia are never present in North American specimens.
Coccotrema is a genus of lichen-forming fungi. It is the type genus of the family Coccotremataceae, in the order Pertusariales. The genus contains 16 species.
Opegraphaceae is a family of lichen-forming and lichenicolous fungi in the order Arthoniales. It was originally proposed by German lichenologist Ernst Stizenberger in 1862. It fell into disuse, but was resurrected in a molecular phylogenetic study of the order Arthoniales published in 2010. It now includes taxa that were previously referred to the family Roccellaceae, its sister group.
Bilimbia is a genus of lichen-forming fungi in the family Ramalinaceae.
Dictyographa is a genus of lichen-forming fungi in the family Opegraphaceae. It comprises three species of corticolous (bark-dwelling), crustose lichens. The genus was originally described by the Swiss scientist Johannes Müller Argoviensis in 1893, who distinguished it from related genera by its unique spore structure and interconnected filaments within its reproductive organs. Dictyographa lichens are characterised by their elongated, slit-like fruiting bodies and spores that are divided by both vertical and horizontal internal walls. The genus has been subject to taxonomic debate, with some researchers proposing to merge it with the related genus Opegrapha. However, genetic studies have since confirmed Dictyographa as a distinct evolutionary lineage. These lichens are found in various parts of the world, including Africa, the Middle East, and Hawaii, typically growing in coastal environments.
Marcelaria is a genus of crustose lichens in the family Trypetheliaceae. It has three species. The genus was circumscribed in 2013 by André Aptroot, Matthew P. Nelsen, and Sittiporn Parnmen, with Marcelaria purpurina assigned as the type species. The genus contains species that were previously in the Laurera purpurina species complex. Species in Marcelaria contain secondary compounds such as red, orange, and yellow anthraquinones, and sometimes lichexanthone. The genus name honours Brazilian lichenologist Marcela Cáceres.
Austroroccella is a single-species genus in the family Roccellaceae. It contains Austroroccella gayana, a saxicolous (rock-dwelling), fruticose lichen. This lichen produces dark to black discs lacking pruina, and it contains roccellic acid as its only lichen product. The genus was circumscribed in 2013 by Anders Tehler, Martin Irestedt, and Damien Ertz based on molecular phylogenetic analysis that showed that the species belongs in an isolated clade in the Roccellaceae along with Dendrographa, Syncesia, and Roccellina.
Roccella galapagoensis is a species of fruticose lichen in the family Roccellaceae. It is endemic to the Galápagos Islands.
