Graphidastra is a genus of lichen-forming fungi in the family Roccellaceae.

Chrysothrix granulosa, the coastal gold dust lichen, is a brilliant yellow, powdery (leprose) lichen that grows in irregular patches mostly on bark (sometimes wood and rock) in shaded dry areas of coastal western North America and western South America. In North America it is found from Mexico to as far north as British Columbia. It can be found in coastal areas of California near Santa Barbara County, and coastal areas of the Sonoran Desert, mostly islands off Baja California. In South America it is found from Chile to Peru. It is found at elevations from sea-level to 400 metres (1,300 ft).

Calvitimela uniseptata is a little-known species of crustose lichen in the family Tephromelataceae. Found in Antarctica, it was described as new to science in 2011. The lichen forms small, wart-like to coral-shaped growths that are grey to greenish-grey in colour, with stalked fruiting bodies up to about a millimetre across. It grows on basalt rock outcrops near a nutrient-enriched site, having been found near old bird nest remains at around 500 metres elevation.

Ancistrosporella is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed in 1995 by Swedish lichenologist Göran Thor, with Ancistrosporella australiensis assigned as the type species. The International Union for Conservation of Nature has classified A. leucophila as a Critically Endangered species due to its limited known distribution in South America and the threats to its habitat from deforestation and land-use changes.

Sagenidiopsis isidiata is a species of corticolous (bark-dwelling) byssoid lichen in the family Roccellaceae. Found in tropical montane rainforests throughout Central America, South America, and the Antilles, it was described as new to science in 2011. The lichen is characterised by its cream-coloured to greyish thallus and numerous pseudoisidia, which are small, cylindrical outgrowths on its surface.

Pulvinodecton is a small genus of lichen-forming fungi in the family Roccellaceae. It comprises two species of corticolous (bark-dwelling) crustose lichens. These lichens are found exclusively in humid tropical rainforests, where they grow on tree bark in shaded locations from sea level to about 400 metres elevation. One species ranges across the Indo-Pacific region while the other is found only in the Seychelles islands. The lichens form thin, greyish crusts on bark that develop distinctive star-shaped fruiting bodies and powdery mounds for reproduction. They can be recognized by their

Lecanographaceae is a family of mostly lichens (also some lichenicolous fungi) in the order Arthoniales. The family was circumscribed in 2014, prompted by a molecular phylogenetic-based restructuring of the Arthoniales.

Erythrodecton is a genus of two species of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed in 1991 by Swedish botanist Göran Thor, with E. granulatum assigned as the type species.

Crypthonia is a genus of lichen-forming fungi in the family Arthoniaceae. It has 16 species. The genus was circumscribed in 2010 by Andreas Frisch and Göran Thor, with Crypthonia polillensis assigned as the type species.

Sporodophoron is a genus of lichen-forming fungi in the family Arthoniaceae. It includes four corticolous (bark-dwelling) crustose lichen species. Sporodophoron is uniquely characterised by the formation of fruiting structures called sporodochia, which are open conidiomata in the form of tufts of conidiophores on the thallus. Although these lichens bear a strong resemblance to Inoderma, another genus within the same family, Sporodophoron's distinct chemical makeup sets it apart from its lichen relatives. Collectively, the genus has a widespread geographical distribution in the Northern

Micarea capitata is a species of moss-dwelling lichen in the family Ectolechiaceae. Described in 2011 from Härjedalen in north-western Sweden, this rarely recorded lichen is characterised by minute black apothecia with a distinctly constricted base and a mottled, darkly pigmented hypothecium. The species grows on shoots of the pleurocarpous moss Hylocomium splendens on rocks in open forests, where it forms an extremely thin, pale grey crust that is easily overlooked in the field.

Herpothallon rubromaculatum is a species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. Found in tropical rainforests of Peru and Venezuela, it was formally described as new to science in 2009 by the lichenologist Göran Thor. It contains neodiffractic acid as a major lichen product, and confluentic acid as a minor component.

Herpothallon rubroechinatum is a species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. It is distinguished by its greyish-white to beige thallus and distinctive rust-red crystals that appear sprinkled on its reproductive structures. The species contains psoromic acid and reproduces primarily through vegetative means rather than spores. Initially documented in Florida, Costa Rica, and Peru, its known range expanded to the Galápagos Islands in 2013, where it inhabits the humid zone of Santa Cruz Island, growing on both native endemic trees and introduced species in

Herpothallon pustulatum is a species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. It was formally described as new to science in 2009 by the lichenologist Göran Thor. It is found in montane forests in Costa Rica, Brazil, and Venezuela. It contains confluentic acid as its major lichen product along with trace amounts of several other substances.

Herpothallon nigroisidiatum is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. Found in Peru, it was formally described as new to science in 2009 by the lichenologist Göran Thor. It contains neodiffractic acid as its major lichen product, along with trace amounts of confluentic acid and chiodectonic acid. It is only known to occur at its type locality, which is a tropical rainforest in the Cordillera Escalera, San Martín. The species epithet nigroisidiatum refers to its pseudisidia, which have a black hypothallus that sometimes projects up

Herpothallon hypoprotocetraricum is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. Found in Tanzania, it was formally described as new to science in 2009 by the lichenologist Göran Thor. The type specimen was collected by Edit Farkas in 1989 from a rocky forest on the south-east slope of Mount Kanga, a hill of the Nguru Mountains in the Mvomero district, Morogoro, Tanzania, at an altitude between 1,200 and 1,300 m (3,900 and 4,300 ft). It is only known to occur at the type locality. The lichen contains hypoprotocetraric acid as its major

Herpothallon globosum is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. Found in São Tomé and Príncipe, it was formally described as new to science in 2009 by the lichenologist Göran Thor. It contains psoromic acid and chiodectonic acid as major lichen products. The lichen is known only from two old collections made by Moller in 1885, at altitudes of 1,200 and 1,500 m (3,900 and 4,900 ft). The species epithet refers to its numerous globose (spherical) and unbranched isidia.

Herpothallon furfuraceum is a species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. Found in Costa Rica, it was formally described as new to science in 2009 by the lichenologist Göran Thor. It is only known to occur in two locations in Costa Rica, at elevations ranging from 900 to 1,350 m (2,950 to 4,430 ft). It contains confluentic acid and chiodectonic acid as major lichen products. The authors suggest that because this lichen resembles a more weakly pigmented version of the more common and widespread Herpothallon rubrocinctum, it may be commonly overlooked by

Herpothallon elegans is a rare species of corticolous (bark-dwelling), crustose lichen in the family Arthoniaceae. Found in Peru, it was formally described as new to science in 2009 by the lichenologist Göran Thor. It contains confluentic acid and lichexanthone as major lichen products. It is only known to occur in tropical rainforest at a couple of locations, with elevations of 850 m (2,790 ft) and about 1,200 m (3,900 ft).
