Pyxine is a genus of foliose lichens in the family Caliciaceae. [2] The genus has a widespread distribution in tropical regions. [3]

The presence or absence of the compound lichexanthone is a character used in classifying Pyxine species; about 20 species contain this compound. This represents the largest group of foliose lichens with the compound. [4]

Punctelia is a genus of foliose lichens belonging to the large family Parmeliaceae. The genus, which contains about 50 species, was segregated from genus Parmelia in 1982. Characteristics that define Punctelia include the presence of hook-like to thread-like conidia, simple rhizines, and point-like pseudocyphellae. It is this last feature that is alluded to in the vernacular names speckled shield lichens or speckleback lichens.

Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was circumscribed in 1994 by Gintaras Kantvilas and John Alan Elix. It was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was circumscribed in 2014 to contain the genus.

Leptogium is a genus of lichen-forming fungi in the family Collemataceae. It has about 110 species. Species formerly classified under Leptogium have since been divided among the genera Leptogium, Pseudoleptogium, and Scytinium.

Astrothelium is a large genus of corticolous (bark-dwelling) lichens in the family Trypetheliaceae. The genus is characterized by a corticate thallus and diverse ascomata structures, which can be simple, aggregated, or forming pseudostromata. Astrothelium is also notable for the carbonized walls of its ascomata, the so-called textura intricata arrangement of cells in these walls, and various forms of distoseptate, transparent spores.
