Pertusaria albineoides is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, A.W.Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected on Alcedo Volcano at an altitude of 1,089 m (3,573 ft), where it was found growing on a partially shaded, rain- and wind-exposed trunk of Scalesia microcephala. The species epithet refers to the similarity to the species Pertusaria albinea, from which it differs by having thin-walled ellipsoid-shaped ascospores that are longer and narrower.
Placomaronea fuegiana is a species of saxicolous (rock-dwelling), crustose lichen in the family Candelariaceae. Found in South America, it was formally described as a new species in 2009 by Martin Westberg and Patrik Frödén. The type specimen was collected by the second author in Tierra del Fuego, Argentina, where it was found growing on sandstone. The species epithet fuegiana refers to the type locality. It also occurs in Pali-Aike National Park, where it grows in the pits of volcanic rocks.
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 astonii is a rare species of crustose lichen in the family Teloschistaceae. Described in 2007, is known for its distinct appearance and very limited distribution in Australia. The lichen has a thin thallus measuring 3–8 mm wide, with confluent spots that are thicker and cracked in the centre, showing a dull rose-orange or dull brown-orange colour, and lecanorine apothecia that transition from being immersed in the thallus to raised above it, revealing a bright reddish-brown disc.
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.
Xanthocarpia erichansenii is a species of terricolous (ground-dwelling), crustose lichen in the family Teloschistaceae. It is found in southwest Greenland, where it grows on loess among mosses.
Lecidea lygommella is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecideaceae. It spreads up to 7 cm wide with a thin thallus varying in colour from whitish and pale grey to rusty red-brown, featuring areolate surfaces with irregularly shaped areoles. Its fruiting bodies range from slightly embedded to sitting atop the thallus and black, flat to slightly convex apothecial discs. Unlike its lookalike Lecidea lygomma, L. lygommella does not produce any secondary chemicals. It is found in New South Wales and Victoria, Australia, where it grows on rocks in alpine areas.
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.
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.
Tetramelas flindersianus is a saxicolous (rock-dwelling) crustose lichen species in the family Physciaceae. First described scientifically in 2020, it is found in Australia.
Buellia arida is a species of saxicolous (rock-dwelling), crustose lichen in the family Caliciaceae. It occurs in Australia. Buellia arida grows up to 4 cm wide, either concealed within or visible on rock surfaces, forming small, fragmented patches. It features an off-white, dull thallus, numerous black apothecia that become convex over time, and spores that evolve from pale to dark brown, characterized by their ellipsoid shape and finely decorated surface.
Buellia cravenii is a species of saxicolous (rock-dwelling), crustose lichen in the family Caliciaceae. It is found in Australia. The lichen spreads up to 3.5 cm wide thick, forming a continuous, grey-white cracked pattern of areoles.
Buellia eldridgei is a rare species of terricolous (ground-dwelling), crustose lichen in the family Caliciaceae, known to occur only in Queensland, Australia.
Buellia kowenensis is a rare species of saxicolous (rock-dwelling), crustose lichen in the family Caliciaceae. It is only known to occur at its original collection site in the Australian Capital Territory of Australia.
Buellia lordhowensis is a little-known saxicolous (rock-dwelling), crustose lichen species in the family Caliciaceae, first described in 2020. It is only known to occur on Lord Howe Island, Australia.
Buellia phillipensis is a little-known species of saxicolous (rock-dwelling), crustose lichen in the family Caliciaceae, described in 2020. It is only known to occur on Phillip Island in the Southwest Pacific.

Amandinea pilbarensis is a little-known species of crustose lichen in the family Physciaceae, First described in 2020, it is found in Australia. It is similar to Amandinea polyxanthonica, but can be distinguished by its smaller ascospores and the presence of calcium oxalate and thiophanic acid in the medulla.
