Lecanographa dialeuca is a species of saxicolous (rock-dwelling) crustose lichen in the family Roccellaceae. It is found in Cape Verde and Europe.
It was first described by Scottish James Stirton in 1874, with the name Opegrapha undulata. The type specimen was collected from Cape Verde, as part of the Challenger expedition of 1872–1876. [3] James Mascall Morrison Crombie mentioned the species in an 1877 publication in which he revised and added his own notes about the lichens collected by Stirton. Crombie noted that the species was the same as one that he had named Opegrapha dialeuca. [4] It was later discovered that the name Opegrapha undulata had already been used by François Fulgis Chevallier in 1824, and consequently, Stirton's use of the name was invalid. Because Crombie had noted synonymy with his Opegrapha dialeuca, that species epithet replaced the unavailable epithet undulata. [5]
José María Egea Fernández and Pilar Torrente transferred the taxon to Lecanographa in 1994, when they circumscribed that new genus as a result of their studies on the family Opegraphaceae. [2] They also proposed that the taxon named Opegrapha huneckii by Gerhard Follmann and Oscar Klement in 1970, collected from Canary Islands, [6] is the same species as Lecanographa dialeuca. [2]
Lecanographa dialeuca is found in coastal areas of Macaronesia. In 2000, the lichen was recorded from Europe. A single specimen was collected from Sálvora Island (Galicia, northwest Spain), an uninhabited island with an oceanic climate. Although it differs slightly in some characteristics from the description given by Egea and Torrente, Graciela Paz-Bermúdez considered the two specimens to represent the same species. The Galician specimen was found on a sheltered granitic rock overhang, growing with other lichens such as Dirina massiliensis , Lecanographa grumulosa , Roccella phycopsis , Sclerophyton circumscriptum , and species of Opegrapha .

Opegrapha is a genus of lichenized fungi in the family Opegraphaceae. Species include:
Lecanographa is a genus of about 40 species of lichens in the family Lecanographaceae. It was circumscribed in 1994 by José M. Egea and Pilar Torrente, with Lecanographa lyncea as the type 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.
Peltula is a genus of small dark brown to olive or dark gray squamulose lichens that can be saxicolous ) or terricolous. Members of the genus are commonly called rock-olive lichens. They are cyanolichens, with the cyanobacterium photobiont from the genus Anacystis. They are umbilicate with flat to erect squamule lobes that attach from a central holdfast or cluster of rhizenes. Lichen spot tests are usually negative.
Tylophorella is a genus of lichen-forming fungi in the order Arthoniales. The genus has not been placed into a family. Tylophorella was circumscribed by Finnish lichenologist Edvard August Vainio in 1890, with Tylophorella polyspora assigned as the type species. T. pyrenocarpoides was added to the genus in 1993.
Niebla homalea is a species of fruticose lichen that grows on rocks in foggy areas along the Pacific Coast of North America, from Mendocino County, California south to Bahía de San Quintín on the main peninsula of Baja California, with an isolated occurrence further south on vertical rock faces above Punta Camachos, and other occurrences in the Channel Islands and on Guadalupe Island. The epithet homalea, given by Acharius, suggests it was in regard to the branches appearing flattened.
Vermilacinia cerebra is a fruticose lichen that grows on trees and shrubs in the fog regions along the Pacific Coast of North America from the Channel Islands and mainland California near Los Angeles to southern Baja California, also occurring in South America in the Antofagasta Province of northern Chile. The epithet is in reference to the apical swollen lobes that resemble the cerebrum of the brain.
Vermilacinia flaccescens is a fruticose lichen that grows on cacti and shrubs in the fog regions along the Pacific Coast of South America, Peru, Chile and in the Juan Fernandez Islands The epithet is in reference to the flaccid thallus but some specimens have been interpreted to have rigid branches.
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.
Punctelia toxodes is a species of foliose lichen in the family Parmeliaceae. The lichen is a member of the Punctelia rudecta species complex. Found in South Africa, it was first formally described as a new species by English botanist James Stirton in 1878 as Parmelia toxodes. Klaus Kalb and Manuela Götz transferred it to the genus Punctelia in 2007. In his 1878 publication, Stirton did not designate a type specimen, so an epitype was designated in a 2016 publication. This epitype was collected from the Cape Floristic Region of South Africa, on Paarl Mountain at an altitude of 530 m (1,740 ft). The lichen grows on bark and on rocks.
Punctelia subalbicans is a species of foliose lichen in the family Parmeliaceae. It is found in Australia and New Zealand, where it grows on the bark of various tree species.
Igneoplaca is a genus in the subfamily Xanthorioideae of the family Teloschistaceae. It contains a single species, the crustose lichen Igneoplaca ignea.
Gyalideopsis buckii is a species of bark-dwelling lichen in the family Gomphillaceae. It is found in the United States.
Xanthoparmelia salazinica is a species of lichen in the family Parmeliaceae. Found in South Africa, it was described as a new species in 1989 by American lichenologist Mason Hale. He classified it in Karoowia, a genus that has since been placed in synonymy with Xanthoparmelia following molecular phylogenetic analysis published in 2010.
Carbacanthographis salazinica is a species of script lichen in the family Graphidaceae. Found in Australia, it was described as a new species in 2001 by lichenologist Alan Archer. The type specimen was collected by Archer in Conglomerate State Forest. Here the lichen was found growing on the bark of a palm tree. Its thallus is thin and grayish-green, with conspicuous white lirellae measuring 1–4 mm long. The specific epithet refers to salazinic acid, the presence of which is a distinguishing characteristic of this species. The lichen also has trace amounts of other secondary chemicals, including consalazinic acid, norstictic acid, and protocetraric acid. In 2005 Archer transferred the taxon to genus Carbacanthographis.
Pulchrocladia ferdinandii is a species of lichen in the family Cladoniaceae. It was first formally described as Cladonia ferdinandii by Swiss lichenologist Johannes Müller Argoviensis in 1882. The specific epithet honours German-Australian botanist Ferdinand von Mueller, who collected the type specimen near Esperance, Western Australia. Rex Filson transferred the taxon to Cladia in 1970. In 2018, it was transferred to the newly circumscribed genus Pulchrocladia.
Siegfried Huneck was a German chemist and lichenologist. Much of his scientific career was hampered by the political situation in the former German Democratic Republic. He rejected pursuing a career in academia, and instead ended up working at the Leibniz Institute of Plant Biochemistry, a public research institute, from 1969 until his retirement in 1993. Despite his relative isolation and restricted freedoms in East Germany, Huneck had numerous professional contacts both in Germany and abroad, and was a highly published scholar. Many of his more than 400 scientific publications dealt with the chemistry of lichen products. He was awarded the Acharius Medal for lifetime achievements in lichenology in 1996.
Opegrapha vulpina is a species of lichenicolous (lichen-eating) fungus in the family Opegraphaceae. It is found in the Czech Republic, Dobruja, Romania, and the Italian Apennine Mountains. It grows parasitically on two species of saxicolous (rock-dwelling), crustose lichens.
Biatora oxneri is a species of corticolous (bark-dwelling) lichen in the family Ramalinaceae. It is found in the Russian Far East and in South Korea.
Variospora cancarixiticola is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in southeastern Spain, where it grows on cancarixite, a volcanic rock known only to occur in that country.
