Amandinea punctata (tiny button lichen) is a crustose brown to gray lichen that grows on wood and rock around the world. It grows on, not in the wood (epiphytic). It prefers bark that is acidic. In California, it is among the most common crustose lichens occurring on trees. Sometimes its thallus is absent, and branches may be covered in its lecideine apothecia. Because of its tolerance of low humidity, it is one of the few epiphytic lichens growing on trees in California deserts, where it commonly grows on the old, dry wood of junipers, and sometimes fallen pinyon pines and oaks, or on their

Fellhaneropsis is a genus of lichen-forming fungi in the family Ectolechiaceae. The genus comprises 11 accepted species as of 2025. These inconspicuous lichens form extremely thin, smooth to powdery films that spread over bark, leaves, or other plant surfaces, and unlike their close relatives in Fellhanera, they produce no detectable lichen products.

Xerotrema is a small genus of fungi in the family Odontotremataceae. It comprises two species. The genus was circumscribed by Martha Allen Sherwood and Brian John Coppins in 1980. The type species, Xerotrema megalospora, is found in the United States and Canada. X. quercicola was added to the genus in 2008. These fungi produce tiny, deeply cup-shaped fruiting bodies on weathered, barkless wood of conifers and hardwoods in temperate regions. While the genus was originally thought to be non-lichenized, at least one species appears to form facultative partnerships with green algae, meaning it

Pyrenula macrospora is a species of corticolous (bark-dwelling crustose lichen in the family Pyrenulaceae. The lichen has a smooth olive-brown to fawn thallus marked with small white spots, and produces curved ascospores within convex fruiting bodies. It grows on the smooth bark of deciduous trees in oceanic climates, where it is found mainly in western coastal regions of Europe, Asia, and Macaronesia.

Phyllopsora rosei is a species of lichen belonging to the family Ramalinaceae. It is native to Western Europe.

Phylloblastia inexpectata is a species of foliicolous (leaf-dwelling) lichen in the family Verrucariaceae. Found in Europe, it was formally described by lichenologists Emmanuël Sérusiaux, Brian John Coppins, and Robert Lücking. The type specimen was collected by the second author in Dunskey Glen Woods (Portpatrick, Scotland), where it was found growing on the leaves of a Prunus laurocerasus tree growing near a stream. It has also been collected in England, southern Italy, Madeira, and Spain.

Ocellularia roseotecta is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. Found in Malaysia, it was formally described as a new species in 2002 by lichenologists Natsurang Homchantara and Brian J. Coppins. The type specimen was collected by the second author in Gunung Mulu National Park (Sarawak); here it was found growing on young trees in a heath forest at an elevation of 150 m (490 ft). It is only known to occur at the type locality. The lichen has a whitish-brown, irregularly cracked thallus and a medulla that is coloured from white to pale pink. The specific

Micarea viridileprosa is a species of crustose lichen in the family Ectolechiaceae that was first described in 2001. This crustose lichen is known to grow on bark, wood, and soil, and is distinguishable by its bright greenish soredia.

Fellhanera gyrophorica is a corticolous species in the family Ectolechiaceae. Previously noted in several publications as an unidentified Fellhanera species, it was formally named and described due to its unique characteristics and lack of ascomata (fruiting bodies).

Buellia arborea is a species of crustose lichen in the family Caliciaceae. It is found in Northern Europe and western North America.

Arthonia thelotrematis is a species of lichenicolous (lichen-dwelling) fungus in the family Arthoniaceae. It was described in 1989 from material collected in western Scotland. The fungus is a parasite of the lichen Thelotrema lepadinum, on whose surface it produces minute, dark fruiting bodies within discrete patches of dead host tissue. It is known from scattered localities in western Britain, the Azores, and France.

Arthonia invadens is a species of lichen-dwelling fungus in the family Arthoniaceae. The fungus produces small, dark brown fruiting bodies that erupt through the bark surface, forming narrow star-shaped or branching patterns typically 0.2–1 mm across. It produces ascospores that are initially colourless and smooth but later become covered with brown granular warts, with the upper cell larger than the lower cells. The species is rare in Britain and Ireland, known from only a few localities including the New Forest, West Cork, and North Devon, where it grows on various hardwood trees including

Arthonia graphidicola is a species of lichen-dwelling fungus in the family Arthoniaceae. The fungus forms tiny reddish- to dark-brown flecks that initially develop beneath the bark surface before breaking through, typically measuring about 0.06–0.16 mm across or forming elongated structures up to about 0.4 mm long. It produces ascospores that are initially colourless and smooth but later become covered in dark brown granular warts, with the upper cell larger than the lower ones. The species is known from western Scotland, where it grows exclusively on the script lichen species Graphis scripta

Arthonia cohabitans is a species of lichenicolous (lichen-dwelling) fungus in the family Arthoniaceae. The fungus forms minute brown-black flecks that develop beneath the bark surface but soon break through and become visible, typically measuring less than 0.2 mm across or forming elongated structures up to about 0.3–0.4 mm long. It produces small ascospores that start out colourless and smooth but later become brown and finely textured, with the upper cell larger than the lower.

Arthonia anglica is a species of lichen-forming fungus in the family Arthoniaceae. The lichen forms grey-white to pale fawn patches on tree bark, bounded by a dark brown line, and is mostly embedded within the outer bark layer. Its reproductive structures are numerous star-shaped to irregularly star-shaped features that are pale to dark reddish-brown and can reach up to 12 mm across in the largest groupings. The species occurs on mature hardwood trees in long-established woodlands, recorded from beech and holly in Britain, and from various hardwoods including maple and hornbeam in eastern

Anisomeridium robustum is a species of corticolous (bark-dwelling) lichen in the family Monoblastiaceae. It is characterised by its distinctive black, rounded fruiting bodies that can be up to half a millimetre across and sometimes produce visible white strings of spores. The lichen grows in old woodlands and parks across western Britain and Ireland, and has more recently been discovered in South Korea and the Azores.
