Opegraphaceae

Cresponea is a genus of lichens in the family Opegraphaceae. The genus, circumscribed in 1993, contains species that were formerly classified in Lecanactis. Cresponea is widely distributed, but most species are found in tropical and subtropical regions. The genus is named in honor of the Spanish lichenologist Ana Crespo.

Sclerophyton is a genus of lichen-forming fungi in the family Opegraphaceae. It has about 15 species. The genus was circumscribed by German lichenologist Franz Gerhard Eschweiler in 1824, with Sclerophyton elegans assigned as the type species.

Ingaderia is a genus of lichen-forming fungi in the family Opegraphaceae. Species in this genus form pale, crusty patches that often crack when thick, and produce elongated fruiting bodies that appear as narrow slits on the surface. The genus was originally established with a single species from South America, but molecular studies published in 2023 expanded its scope to include several species previously classified in other genera such as Llimonaea and Paraingaderia. Species are distinguished by their thick, dark fruiting body walls, elongated ascospores divided by cross-walls, and the presen

Llimonaea is a genus of lichen-forming fungi in the order Arthoniales. The genus has been placed into the family Opegraphaceae. These lichens form thin, firmly attached crusts that vary from chalky white and grey to olive-green or dark brown, often edged by a neat black line and characterized by rounded or scribble-like reproductive structures that sit flush with the surface. Established as a genus in 1991, Llimonaea species are distinguished by their partnership with orange-tinged green algae, their spindle-shaped spores with multiple cross-walls that gradually turn brown with age, and their

Combea is a genus of lichens in the family Opegraphaceae. It has two species. The genus was circumscribed by Italian botanist Giuseppe De Notaris in 1846.

Opegraphaceae is a family of lichen-forming and lichenicolous fungi in the order Arthoniales. It was originally proposed by German lichenologist Ernst Stizenberger in 1862. It fell into disuse, but was resurrected in a molecular phylogenetic study of the order Arthoniales published in 2010. It now includes taxa that were previously referred to the family Roccellaceae, its sister group.

Pentagenella is a genus of lichen-forming fungi in the family Opegraphaceae. It contains five species.
