The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark.
Lithoglypha is a fungal genus in the family Acarosporaceae. It is monotypic, containing the single species Lithoglypha aggregata, a saxicolous (rock-dwelling), crustose lichen found in South Africa.
Badimiella is a genus of lichen-forming fungi in the family Pilocarpaceae. It has two species of foliicolous (leaf-dwelling) lichens.
Psilolechia is a genus of four species of crustose lichens. It is the only member of Psilolechiaceae, a family that was created in 2014 to contain this genus.
The Trypetheliaceae are a family of mainly lichen-forming fungi in the order Trypetheliales. The family consists almost exclusively of corticolous (bark-dwelling), crustose lichens with an almost strictly tropical distribution.
Parmotrema is a genus of lichen belonging to the family Parmeliaceae. It is a large genus, containing an estimated 300 species, with a centre of diversity in subtropical regions of South America and the Pacific Islands.
Phacopsis is a genus of lichenicolous (lichen-dwelling) fungi. They are parasites of members of the large lichen family Parmeliaceae, of which they are also a member. Originally proposed by Edmond Tulasne in 1852 to contain 3 species, Phacopsis now contains 10 species, although historically, 33 taxa have been described in the genus. Many of the species are poorly known, some of them having been documented only from the type specimen.
Solenopsora is a genus of lichen-forming fungi in the family Catillariaceae. It has 15 species, with a mostly Northern Hemisphere distribution.
Schaereria is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes. Most Schaereria species are crustose lichens that live on rocks. Schaereria was first proposed by Gustav Wilhelm Körber in 1855 and was later taken up by other lichenologists despite periods of disuse.
Sporastatia is a genus of crustose lichens in the family Sporastatiaceae. It has four species. Sporastatia lichens are long-lived species that grow on siliceous or weakly calcareous rocks in arctic and alpine locales.
Pyrenodesmia is a genus of lichen-forming fungi in the family Teloschistaceae. The genus currently includes 23 recognized species but is believed to contain many more unnamed taxa. The genus was circumscribed in 1852 by Italian lichenologist Abramo Bartolommeo Massalongo. It is characterised by the complete absence of anthraquinones and the presence of Sedifolia-gray pigments in both the thallus and apothecia. These lichens are typically found in calcareous outcrops in the Northern Hemisphere, with biodiversity centres in the Mediterranean basin, Central Asia, and arid regions of western North America.
Sporodictyon is a genus of crustose lichens in the family Verrucariaceae. It has 10 species. Most species grow on rocks, although some have been recorded overgrowing soil and mosses.
Celotheliaceae is a family of fungi in the monotypic order Phaeomoniellales. It contains 27 species of crustose lichens with thalli that are more or less immersed in tree bark.
Clandestinotrema is a genus of lichen-forming fungi in the family Graphidaceae. It has 17 species. They typically inhabit montane and cloud forest at higher elevations in the tropics.
Parmotrema perforatum, commonly known as the perforated ruffle lichen, is a species of foliose lichen in the family Parmeliaceae. The lichen was first formally described as new species in 1787 by Nikolaus Joseph von Jacquin. It was transferred to the genus Parmotrema by Italian lichenologist Abramo Bartolommeo Massalongo in 1860. The lichen is characterized by its apothecia often having a perforated hole in the center. The genus Parmotrema has a naked (white) zone on the underside margin and often has long hair-like projections on the lobe edges called cilia; P. perforatum is no different. The thallus is gray and lacks the yellow-green tones that is seen in lichens with usnic acid. There are no asexual structures, but there are apothecia that have the characteristic hole in the center.
Blastenia ferruginea is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. It has a cosmopolitan distribution.
Nitidochapsa is a genus of lichen-forming fungi in the family Graphidaceae. It has five species of corticolous (bark-dwelling), crustose lichens.
Pyrenodesmia variabilis is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Characteristics of the species include its dark, areolate thallus, and its dark, sessile (stalkless) apothecia. It occurs on nutrient-rich limestone surfaces in Northern Europe, North America, Central America, and Asia.
Pseudotopeliopsis is a genus of lichen-forming fungi in the family Graphidaceae. It has two species.
