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

Amandinea is a genus of lichenized fungi in the family Caliciaceae. Genetic studies indicates that the genus Amandinea and Buellia are the same, although this is not widely accepted.

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).

Anzina is a fungal genus of uncertain familial and ordinal classification in the subclass Ostropomycetidae. It is monotypic genus, containing the single crustose lichen species Anzina carneonivea. The lichen occurs mainly in mountainous regions of Europe and western North America, where it grows on the bark of coniferous trees and on decaying organic matter. The genus name honours the Italian botanist Martino Anzi, who first described the species in 1868. The genus was established more than a century later, after microscopic work indicated that the species had a distinctive set of characters.

Reichlingia leopoldii is a species of lichen-forming fungus (a lichenised hyphomycete) in the family Arthoniaceae. It forms greyish-green patches up to several centimetres across on hard siliceous rocks such as basalt, often in sheltered overhangs and crevices. The fungus reproduces asexually through distinctive chocolate-brown, branched spores that develop on the thallus surface, and no sexual reproductive structures are known. In continental Europe the species is rare and scattered, occurring mainly on the bark of veteran oaks in long-established woodlands from the Netherlands and Belgium

Hafellia is a genus of lichen-forming fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions. The genus is named in honour of the Austrian lichenologist Josef Hafellner. The genus was proposed by the German lichenologist Klaus Kalb in 1986 to contain two bark-dwelling species, formerly in genus Buellia, with callispora-type spores. These ascospores have ridged walls, and are thin walled at their tips at early states of their differentiation.

Reichlingia is a genus of lichen-forming fungi in the family Arthoniaceae. It has seven species. The genus was originally circumscribed by Paul Diederich and Christoph Scheidegger in 1996, with Reichlingia leopoldii as the type, and at that time, only species. The fungus was at first thought to be a lichenicolous (lichen-dwelling) fungus, but is now considered a lichenised hyphomycete.
