Lecania sessilisoraliata is a species of saxicolous (rock-dwelling), crustose lichen in the family Ramalinaceae. It is found on rock outcrops in the mountainous Burdur region of Turkey.
The lichen was formally described as a new species in 2017 by lichenologists André Aptroot and Kenan Yazıcı. The type specimen, collected by the second author near Esirlik village (Bucak, Burdur) at an altitude of 859 m (2,818 ft), was found growing on calcareous rock. The species is only known to occur in Turkey, usually on limestone. The species epithet refers to the characteristic sessile soralia (i.e., vegetative propagules without a stem, stalk, attached to the thallus surface). [1]
The crust-like thallus of Lecania sessilisoraliata is pale olivaceous brown to pale olivaceous green and measures up to 2.5–3 cm (1.0–1.2 in) in diameter. The crust thickness is greatest at its centre, about 1–2 mm. The crust comprises smaller areoles crowded together, each measuring 0.2–0.6 mm in diameter. Whitish soralia are raised above the level of the thallus and are sessile; they are largely crowded towards the thallus centre measuring up to 0.8–1 mm in diameter. The soredia are granular, each measuring 30–50 μm in diameter. The asci contains eight spores and are of the Bacidia -type, with dimensions of 8.5–12 by 25.5–30 μm. Ascospores are hyaline, ellipsoid in shape with a single septum, and measure 8.5–9.8 by 2.4–3.1 μm. [1]
Acarospora flavisparsa is a species of lichen in the family Acarosporaceae. Found in Portugal and Spain, it was described as new to science in 2011. The lichen grows on acidic rock walls in inland areas.
Malmidea is a genus of crustose lichens and the type genus of the family Malmideaceae. It was established in 2011 to contain a phylogenetically distinct group of species formerly placed in the genus Malcolmiella. Malmidea comprises more than 50 mostly tropical species that grow on bark, although a few grow on leaves.
Punctelia perreticulata is a widely distributed species of foliose lichen in the family Parmeliaceae. It occurs in Mediterranean Europe and Russia, North America, South America, Australia, and New Zealand, where it grows on rocks, bark, or wood. Its main distinguishing features are its thallus surface, marked with many shallow depressions, grooves, or pits, and sorediate pseudocyphellae. The lower side of the thallus is ivory to tan towards the centre and the major secondary metabolite in the medulla is lecanoric acid. A lookalike species with which it has been historically confused is Punctelia subrudecta; this lichen can be distinguished from Punctelia perreticulata by the texture of the thallus surface, or, more reliably, by the length of its conidia.
Punctelia graminicola is a species of foliose (leafy) lichen in the family Parmeliaceae. It grows on rocks, and, less frequently, on bark in North America, South America, and East Africa. It has a blue-grey thallus measuring up to about 15 cm (6 in), covered with tiny pores called pseudocyphellae. Sometimes the lichen forms small lobes that project out from the surface. Fruiting bodies are uncommon in this species; if present, they resemble small cups with a brown internal disc measuring 3–10 mm (0.1–0.4 in) in diameter. A lookalike species, Punctelia hypoleucites, is not readily distinguishable from Punctelia graminicola by appearance or habitat alone; these species can only be reliably differentiated by examining the length of their conidia.
Ramalina erosa is a species of fruticose lichen in the family Ramalinaceae. It was described as a new species by Hildur Krog in 1990. The type specimen was collected from Pico do Facho on Porto Santo Island (Portugal), where it was found growing on acidic rock at an elevation of 500 m (1,600 ft).
Fuscidea muskeg is a species of crustose lichen in the family Fuscideaceae. Found in Alaska, it was described as a new species in 2020 by Tor Tønsberg and Martina Zahradníková. The type species was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park. Here it was found growing on a branch of the tree Pinus contorta in muskeg. The specific epithet muskeg is an Algonquin word for a blanket bog.
Cladonia lichexanthonica is a rare species of saxicolous (rock-dwelling) lichen in the family Cladoniaceae. Found in Bahia, Brazil, it was formally described as a new species in 2018 by lichenologists André Aptroot and Marcela Eugenia da Silva Cáceres. The type specimen was collected by the authors from the Morro do Pai Inácio at an altitude between 1,050 and 1,140 m ; here the lichen was found growing on siliceous sandstone rock in a transitional forest. Cladonia lichexanthonica is only known to occur at the type locality, and is only known from the type specimen. The lichen has a squamulose (scaley) thallus measuring up to 10 cm (4 in) in diameter; this consists of a 5-millimetre (0.2 in) thick crust comprising individual crowded squamules, pale-olive green to olive brown, measuring 1–5 mm in size. The specific epithet lichexanthonica refers to the presence of lichexanthone, a secondary compound that was not previously known to occur in genus Cladonia.
Lepra lichexanthonorstictica is a species of crustose and corticolous (bark-dwelling) lichen in the family Pertusariaceae. Found in Brazil, it was formally described as a new species in 2021 by Dutch lichenologist André Aptroot. The type specimen was collected by Aptroot from the summit area of Quiriri (Garuva), at an altitude of 1,350 m (4,430 ft); here it was found growing on the bark of a pine tree. The lichen is named after its two major secondary compounds, lichexanthone and norstictic acid. Lepra lichexanthonorstictica has a thin, smooth and glossy thallus ranging in colour from white to very pale yellowish. The thallus has discrete, rounded soralia measuring about 0.5–0.9 mm in diameter.
Buellia lichexanthonica is a species of saxicolous (rock-dwelling) lichen in the family Caliciaceae. Found in Brazil, it was formally described as a new species in 2017 by lichenologists André Aptroot and Marcela Eugenia da Silva Cáceres. The type specimen was collected by the authors near the Poço Azul, at an altitude of about 450 m (1,480 ft); here, in Cerrado, it was found growing on sandstone. The lichen has a thin (0.1–0.2 mm), dull yellow thallus covered with xanthone crystals. Its ascomata are round and black, about 0.2–0.5 mm in diameter with a flat disc. The ascospores are dark brown with an ellipsoid shape, one septum, and measure 11–13 by 6–7.5 μm. The specific epithet lichexanthonica refers to the presence of 4,5-dichlorolichexanthone, a lichexanthone derivative that is found in the cortex of the thallus.
Neoprotoparmelia capitata is a species of corticolous (bark-dwelling) and crustose lichen in the family Parmeliaceae. It is found in eastern North America.
Phacopsis australis is a species of lichenicolous (lichen-dwelling) fungus in the family Parmeliaceae. It is found in a few locations in South Africa, where it grows on the thalli of several species of the leafy lichen genus Xanthoparmelia. Unlike other members of genus Phacopsis, the fungus does not induce the formation of galls in its host.
Leucodecton coppinsii is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. It is found in lowland forests of Sarawak, Malaysia.
Mazaediothecium uniseptatum is a species of calicioid lichen in the family Pyrenulaceae. Found in French Guiana, it was formally described as a new species in 2015 by Dutch lichenologist André Aptroot. The type specimen was collected near the village sentier Limonade in Saül at an altitude of 300 m (980 ft); here, in a mixed forest, the lichen was found growing on the higher trunk of a Protium tree. It has a dull, greyish-white thallus that lacks a cortex and is surrounded by a brown prothallus line. The apothecia are black but covered in their upper half with a golden yellow pruina; they are about 0.2 mm in diameter and up to 0.6 mm high. The asci soon disintegrate to form a mazaedium layer. Ascospores are pale grey with a shape ranging from ellipsoid to spindle-shaped (fusiform), and measure 7.0–12.0 by 5.0–7.5 μm; they contain a single septum. It is this last feature that is referenced in the species epithet uniseptatum.
Astrothelium sipmanii is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. It is found in Guyana.
Lobariella sipmanii is a species of foliose lichen in the family Peltigeraceae. It is found in high-altitude páramo in Cundinamarca, Colombia.
Loxospora cristinae is a fungal species classified in 2018, found in a few European countries. It belongs to the division Ascomycota and the family Sarrameanaceae. It was first identified and described in the 19th century, but the species would not be correctly classified until almost two centuries later. Loxospora cristinae is a sterile crustose lichen, meaning it reproduces by a type of vegetative spore that has evolved specifically to produce morphological structures.
Buellia schaereri is a species of lichen in the family Caliciaceae. It was formally described as a new species in 1849 by Italian botanist Giuseppe De Notaris. The botanical name honours Swiss pastor and lichenologist Ludwig Schaerer. It is a widely distributed lichen, occurring in Africa, Asia, Northern and Central Europe, Macaronesia, Central America, and North America. It grows on the bark and wood of trees, especially conifers and oak.
