Neobrownliella brownlieae is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed in Australia.
Bryoria hengduanensis is a species of lichen of the genus Bryoria. It was described as new to science in 2003 by lichenologists Li-Song Wang and Hiroshi Harada. It is found in the Hengduan Mountains of southern China, where it grows on twigs and branches in coniferous forests at elevations of 3,000–4,000 metres (9,800–13,100 ft). The Hengduan Mountains is a region of high Bryoria biodiversity, as 24 species are known from this area.
Pyxine sorediata, commonly known as mustard lichen, is a widely distributed species of foliose lichen in the family Caliciaceae. It has a subtropical to warm temperate distribution, and grows on bark, rocks, and moss as substrates. Pyxine sorediata has been reported from regions of North America, Europe, Africa, Asia, and Australasia.
Allocetraria corrugata is a species of foliose lichen in the family Parmeliaceae. It is found in high-elevation locations in Yunnan, China, where it grows on rocks with mosses.
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It comprises 15 formally described species, one subspecies, and three undescribed species of crustose or squamulose that are predominantly saxicolous (rock-dwelling). The genus is characterized by its distinct lobes, orange zeorine apothecia when present, and the frequent occurrence of asexual propagules such as schizidia, isidia, or soredia. A key diagnostic feature is the presence of calcium oxalate crystals in the thallus medulla of many species.
Filsoniana lhasanensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Tibet, where it grows on rocks at altitudes between 4,200 and 4,432 m. This species is defined by its reduced, vivid orange appearance and unique, aggregated reproductive structures.
Upretia is a genus of lichen-forming fungi in the family Teloschistaceae. It has three species of saxicolous (rock-dwelling), crustose lichens. Upretia is characterised by its small ascospores and narrow, rod-shaped conidia. The distribution of the genus ranges from mid-altitude rocky terrains in India to both arid and higher altitudinal environments in China.
Pyrenodesmia micromontana is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Found in the Orenburg region of Russia, this species prefers to grow on lime-rich schist and sandstone boulders and pebbles in scrubs and steppes.
Caloplaca fluviatilis is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in the Republic of Tyva in Siberia.
Placolecis kunmingensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Catillariaceae. It is found in Yunnan, China. The lichen is characterised by a thallus that is areolate to squamulose in its centre, forming irregular patches or clumps 10–50 mm wide, as well as its ellipsoid or spherical ascospores with slightly thickened wall.
Placolecis sublaevis is a species of saxicolous (rock-dwelling), crustose lichen in the family Catillariaceae. It is found in Yunnan and Sichuan, China. The crust-like, radiating body of the lichen forms irregular patches or clumps and includes numerous false conidiomata, a type of asexual reproductive structure, within its thallus. Its lobes, dark brown and slightly flattened at the top, form larger groups at the edges and contain an upper layer composed of loosely interwoven cells and a lower inner tissue that varies from reddish-orange to white.
Filsoniana ferdinandmuelleri is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Australia. The lichen has a squamulose (scaly) thallus, with a range of bright yellow to greenish-yellow and brownish-orange colours in its soredia and apothecia, respectively. The areoles of this lichen are varied in size, slightly raised from the thallus surface, and each carries one to four apothecia. The soralia are rounded or irregularly shaped, covering most of the thallus surface as a yellow to greenish-yellow mass. The apothecia have dark brownish-orange discs, surrounded by slightly paler yellow margins, with the spore-bearing asci containing typically eight brownish-golden ascospores.
Coppinsiella is a genus of lichen-forming fungi in the family Teloschistaceae. It contains five species of corticolous and saxicolous crustose lichens with a distribution in Europe, Asia, and North America. Coppinsiella bears resemblance to the genus Athallia, but it is distinguished by its more developed thallus, typically featuring distinctive crater-like soralia and zeorine-form apothecia, which lack a thalline margin.
Lecaimmeria is a genus of lichen-forming fungi in the family Lecideaceae. Established in 2022, it comprises 13 species of lichens that grow on rock surfaces (saxicolous) and form a thin, crust-like covering (crustose) on their substrate. These lichens are characterised by their glossy, orange to red-brown outer layer (thallus) and sunken fruiting bodies (apothecia) with red-brown centres. Lecaimmeria species are typically found in harsh environments at high altitudes or latitudes, particularly in mountainous regions of western China and across parts of Eurasia. The genus was created to accommodate species previously classified under Immersaria that shared certain distinct features, following molecular analysis that revealed they formed a separate group.
Pseudoheppia is a fungal genus in the family Lichinaceae. It contains a single species, Pseudoheppia schuleri, a saxicolous (rock-dwelling) squamulose lichen.
Gloeoheppia is a genus of lichen-forming fungi in the family Gloeoheppiaceae. It comprises five species. The genus is distinguished from similar-looking lichens like Heppia by its internal structure, the nature of its photobiont, and details of its reproductive structures.
Pseudopeltula is a genus of lichen-forming fungi in the family Gloeoheppiaceae. Established in 1995 by the lichenologist Aino Henssen, the genus currently includes four recognised species. These small cyanolichens are characterised by their squamulose (scaly) to peltate (shield-shaped) thalli, which lack a lower cortex and are attached to the substrate by rhizines. A key feature of Pseudopeltula is its complex apothecia, which have hymenia that often become divided by sterile tissue as they mature. The genus is primarily found in arid and semi-arid regions of North America, Mexico, and the Caribbean, where species typically grow on soil, rock, or thin soil over rock, often forming part of biological soil crusts in desert environments.
Peltula polycarpa is a species of saxicolous (rock-dwelling), squamulose lichen in the family Peltulaceae. First described in 2022, it is endemic to Beijing's Mentougou District in China.
Peltula submarginata is a species of saxicolous (rock-dwelling), squamulose lichen in the family Peltulaceae, first described in 2022. It occurs in China.
