Sigridea is a genus of lichenized fungi in the family Roccellaceae. The genus was circumscribed by Anders Tehler in Cryptog. bot. vol.3 (2) on page 145 in 1993. The genus name of Sigridea is in honour of Sigrid Tehler, who was the daughter of the author (of the genus), Anders Tehler.

Redonographa is a genus of lichen-forming fungi in the monogeneric family Redonographaceae. It has five species.

Paralecanographa is a single-species fungal genus in the family Roccellaceae. The genus was established in 2011 when genetic studies revealed that its single species does not belong where it had been previously classified and needed its own separate genus. This unusual lichen begins life as a parasite on other coastal lichens before eventually taking over and replacing its host, producing small black fruiting bodies that can appear as either tiny slits or rounded discs.

Dirina mexicana is a species of saxicolous (rock-dwelling), crustose lichen in the family Roccellaceae. First identified in Mexico, it displays distinctive characteristics which set it apart from other species within the same genus. The lichen is unique for its varied hues and certain chemical characteristics that are seen in its thallus, or vegetative tissue. Typically growing on vertical or overhanging rocks and cliffs, Dirina mexicana can be found in specific regions across Mexico.

Alyxoria varia is a widely distributed species of corticolous (bark-dwelling), crustose lichen in the family Lecanographaceae. Its common name, scribble lichen, refers to the form of its ascomata (fruiting bodies), which are long or short, sometimes branched, and with blackened walls and bases. The thallus of the lichen is hidden mostly within the bark itself and barely visible.

Alyxoria ochrocheila is a species of lichen in the family Lecanographaceae. It has a cosmopolitan distribution, and was formally described by William Nylander in 1865.

Sparria is a small genus of lichen-forming fungi in the family Opegraphaceae.

Roccellographaceae is a family of lichen-forming fungi in the order Arthoniales. It contains three genera: Dimidiographa, Fulvophyton, and Roccellographa.

Psoronactis is a monotypic fungal genus in the family Roccellaceae. It contains the single species Psoronactis dilleniana, a saxicolous (rock-dwelling), crustose lichen. The lichen grows as a pale grey-to-fawn crust that spreads across the face of the rock while its black, pin-head-sized fruit bodies sit flush with, or slightly above, the surface.

Pseudoschismatomma is a monotypic fungal genus in the family Roccellaceae. It contains the single species Pseudoschismatomma rufescens, a corticolous (bark-dwelling), crustose lichen. The species was originally described in 1794 but was reclassified into its own genus in 2014 following DNA analysis that revealed it was distinct from similar-looking lichens. This inconspicuous lichen forms a very thin, olive to reddish-brown crust on tree bark and is easily overlooked due to its paint-like appearance that blends closely with its substrate. It is known from temperate Europe, with confirmed

Lecanographaceae is a family of mostly lichens (also some lichenicolous fungi) in the order Arthoniales. The family was circumscribed in 2014, prompted by a molecular phylogenetic-based restructuring of the Arthoniales.

Gyrographa is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed in 2014 by Damien Ernst and Anders Tehler, with Gyrographa gyrocarpa assigned as the type species. This lichen, originally described by Julius von Flotow in 1825, was first placed in the genus Opegrapha. Species in the genus have a crustose thallus lacking a cortex, and a dark brown prothallus. The photobiont partner is trentepholioid. The hypothecium is thick and carbonised, and the ascospores lack a gelatinous sheath; these characteristics distinguish it from Opegrapha species. The genus

Feigeana is a genus of lichenized fungi in the family Roccellaceae. A monotypic genus, it contains the single species Feigeana socotrana, first reported from Yemen in 1995. The genus name of Feigeana is in honour of Guido Benno Feige (1937 - 2007), a German botanist (Lichenology and Mycology) and also Professor of Botany in Essen. He also established the Botanical Garden of the University of Duisburg-Essen. The genus was circumscribed by Bruno A. Mies, Helge Thorsten Lumbsch and Anders Gunnar Tehler in Mycotaxon Vol.54 on page 156 in 1995.
