Caloplaca sol is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. [2] It is found on limestone and basic siliceous rocks along the southern and western shores of Great Britain.
The lichen was formally described as a new species in 2018 by the lichenologist Alan Orange. The species epithet sol, derived from the Latin word for "sun", was chosen to reflect the rich yellow colour of its often circular thalli , and its preference for growing on dry, sun-exposed rocks. [1]
The lichen features a prominent, crust-like, non- placodioid , orange-yellow body with cracks, and fruiting bodies (apothecia) that are up to about 0.66 millimetres in diameter. Its spores are approximately 11.0 to 13.0 micrometres in length, with a septum (a dividing wall or partition) about 0.4 times the length of the spore. The species is found exclusively near coastal areas in southern and western Britain, with known locations ranging from Dorset and Cornwall up to North Wales. [1]
Caloplaca sol, with its well-defined, cracked- areolate , completely epilithic thallus and sessile apothecia the same colour as its thallus, can be easily confused with other species in the field. It is often mistaken for a morph of Flavoplaca marina , which typically has a darker orange colour and more convex areoles. Flavoplaca marina is commonly found in the splash zone of seashores, sometimes extending above the high-water mark on sea-facing slopes. Its areoles are usually thicker and strongly convex near the shore, but those found above the splash zone may resemble C. sol more closely, presenting challenges in distinguishing individual specimens based solely on morphology. [1]
Flavoplaca maritima differs from C. sol in its more convex areoles that tend to become isolated as the thallus ages, and its young apothecia often feature a yellow crenulate thalline margin. Another species, Gyalolechia flavovirescens , has large orange apothecia, which contrast sharply with its yellow epilithic thallus. Xanthocarpia diffusa , typically found on damp or poorly drained surfaces and not in coastal habitats in Great Britain, has a less developed epilithic thallus and ascospores with a much narrower septum. Finally, Athallia vitellinula , as defined by Ulf Arup, is a non-maritime species characterised by a thin, inconspicuous, discontinuous pale yellow thallus, and small apothecia up to 0.44 mm in diameter in British specimens.

Catenarina desolata is a species of lichen in the family Teloschistaceae. It was formally described as a new species in 2014 by lichenologists Ulrik Søchting, Majbrit Søgaard, and Arve Elvebakk. It is predominantly found in the southernmost parts of Chile, with some instances in Antarctica and the Kerguelen Islands. Characterised by its dark reddish-brown to almost purple apothecia, this species of lichen was originally thought to be lichenicolous, meaning it grows on other lichens, particularly Aspicilia species. The later discovery non-lichen-dwelling examples from James Ross Island in the Antarctic Peninsula suggests that it is not exclusively lichenicolous. Its distinctive secondary compound, 7-chlorocatenarin, sets it apart from other lichens in the region.
Charcotiana is a single-species genus in the family Teloschistaceae. It contains the species Charcotiana antarctica, a crustose lichen found in Antarctica.
Caloplaca aliciae is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Australia. It is characterised by a thallus that can grow up to 2 cm wide, featuring colours from dull pink to dull brown, with small, dispersed, flat areoles that are irregularly shaped and occasionally dissected by cracks, displaying a whitish, dull pink, or dull orange-brown surface. Its apothecia are lecanorine in form, initially immersed but often rising above the areoles, with each areole containing one or two apothecia that have a thalline margin matching the thallus colour.
Caloplaca conranii is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. The lichen has a bright yellow thallus about 1–2 cm wide, featuring a thick texture with convex, pustule-like formations around the edges and occasionally forming clusters in the centre. Its apothecia are quite large and heavy, ranging from 0.4 to 1.5 mm in diameter, with a flat, dull orange or brownish-orange disc, and long, narrow ascospores.
Caloplaca streimannii is a little-known species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Found in New South Wales, Australia, it is characterised by its powdery soredious mass and numerous tiny apothecia.
Elixjohnia bermaguiana is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Australia. The lichen is characterised by its varying areoles, which are thin to moderately thick, flat to slightly convex, and range from bright yellow to whitish in colour, sometimes with a greenish-yellow hue. Its apothecia are small, with a distinct orange margin and a raised brownish-orange or yellowish-brown disc.
Filsoniana kiamae is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Australia. The lichen forms small rosettes with brownish-orange areoles, and it occasionally develops isidia. Its rare apothecia are round, with brownish-orange margins and a reddish disc.
Filsoniana rexfilsonii is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2007. The thallus of Filsoniana rexfilsonii comprises brownish-orange squamules each hosting one to four reproductive structures.
Neobrownliella montisfracti is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Australia. The small lichen has dull pink to grey areoles, characterised by completely immersed, reddish to pink-brown apothecia and lacking soredia and isidia. Its areoles are closely pressed against the substrate, with the apothecia containing small, elongated ascospores and narrowly rod-shaped conidia.
Sirenophila maccarthyi is a species of corticolous/lignicolous, crustose lichen in the family Teloschistaceae. It has a thallus that is whitish or greyish, often inconspicuous and not always continuous, which can appear darker or dirty grey near its numerous, clustered apothecia. Sirenophila maccarthyi is distributed across regions including Western Australia, New South Wales, Victoria, Tasmania, and New Zealand, in both coastal and inland habitats. It typically grows on the bark and dead wood of a wide range of trees and shrubs such as Acacia sophorae, Araucaria excelsa, and various Eucalyptus species.
Caloplaca letrouitioides is a little-known species of corticolous (bark-dwelling), crustose lichen belonging to the family Teloschistaceae, described in 2011. It is known to occur in Victoria, Australia. The species was named for its superficial resemblance to species in the genus Letrouitia. The anatomical characteristics of Caloplaca letrouitioides, particularly the well-developed true exciple and the unexpanded paraphyses tips, along with the absence of algae in the apothecia, set it apart from other species in the genus.
Caloplaca sterilis is a corticolous (bark-dwelling), crustose lichen belonging to the family Teloschistaceae, described in 2011. It is primarily found in steppe and sand dune habitats in the Black Sea region, and has been recorded from Bulgaria, Romania, southwest Russia, and Ukraine. Caloplaca sterilis is characterised by tiny squamules/areoles with contrasting pale greyish-green to greenish soredia. It is easily overlooked and challenging to identify when completely sorediate and sterile, especially as its soredia do not contain the typical Sedifolia-grey pigment.
Gintarasiella is a single-species genus in the fungal family Teloschistaceae. It contains the species Gintarasiella aggregata, a saxicolous (rock-dwelling), crustose lichen that is found in Australia. The lichen forms uneven, pillow-like patches up to 30 mm across, distinguished by its yellow-orange areoles that are tightly packed or spread out and soon covered by many apothecia. These fruiting bodies start as zeorine in form and later become biatorine, ranging from 0.3 to 1 mm wide and often appearing distorted due to their dense clustering.
Caloplaca nothocitrina is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Its thallus is up to 8 mm in diameter and deep yellow in colour. It comprises small dispersed areoles, occasional concave soralia, and circular apothecia with a bright yellow margin and a dull dark yellowish or brownish disc.
Caloplaca patagoniensis is a species of lignicolous (wood-dwelling), crustose lichen in the family Teloschistaceae. It is found in Chile. It forms small thallus patches, with distinctive areoles that change from whitish or greyish-yellow to deep orange or brownish-orange, often covered by a bright orange blastidious mass. Its fruiting bodies (apothecia) are dark reddish-orange and initially immersed in the substrate, while its spores are ellipsoid to elongated, and the species contains parietin, turning purple when exposed to a potassium hydroxide solution.
