Verrucariaceae is a family of lichens and a few non-lichenised fungi in the order Verrucariales. The lichens have a wide variety of thallus forms, from crustose (crust-like) to foliose (bushy) and squamulose (scaly). Most of them grow on land, some in freshwater and a few in the sea. Many are free-living but there are some species that are parasites on other lichens, while one marine species always lives together with a leafy green alga.
Porina is a genus of lichens in the family Trichotheliaceae. A 2020 estimate places about 145 species in the widespread genus.
Tapellaria is a genus of leaf-dwelling lichens in the family Pilocarpaceae. The genus was circumscribed by lichenologist Johannes Müller Argoviensis in 1890, with Tapellaria herpetospora assigned as the type species.
Mazosia is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1854.
Anisomeridium is a genus of lichens in the family Monoblastiaceae. The type species was originally named Arthopyrenia xylogena by Swiss botanist Johannes Müller Argoviensis in 1883; in 1928, Maurice Choisy defined the genus Anisomeridium, designating A. xylogena the type species.
Endocarpon is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. The genus was circumscribed by German bryologist Johann Hedwig in 1789.
Thelidium is a genus of lichen-forming fungi in the family Verrucariaceae. The genus was circumscribed in 1855 by Italian lichenologist Abramo Bartolommeo Massalongo, who assigned Thelidium amylaceum as the type species.
Staurothele is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. It has about 40 species. When the fungus is part of a lichen, the genus of lichen is commonly called rock pimples.
Psoroglaena is a genus of lichen-forming fungi in the family Verrucariaceae. The genus was circumscribed by Johann Müller Argoviensis in 1891, with Psoroglaena cubensis assigned as the type species.
Coenogonium is a genus of filamentous lichens in the monotypic family Coenogoniaceae. It has about 90 species. Most species are leaf-dwelling or grow on bark, although a few are known to grow on rocks under certain conditions, and some are restricted to growth on termite nests. The genus was circumscribed in 1820 by German naturalist Christian Gottfried Ehrenberg.
Hydropunctaria is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. The genus includes both aquatic and amphibious species, with members that colonise either marine or freshwater habitats. The type species, Hydropunctaria maura, was formerly classified in the large genus Verrucaria. It is a widely distributed species common to littoral zones. Including the type species, five Hydropunctaria lichens are considered marine species: H. adriatica, H. amphibia, H. aractina, H. orae, and H. oceanica.
Bathelium is a genus of lichen-forming fungi in the family Trypetheliaceae.
Graphina is a genus of script lichens in the family Graphidaceae. It has about 25 species. The genus was circumscribed in 1880 by Swiss lichenologist Johannes Müller Argoviensis. Müller Argoviensis did not indicate a type species for the genus in his original publication; David Hawksworth proposed to designate Graphina anguina as a lectotype in 1981.
Willeya fusca is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Found in Vietnam, it was formally described as a new species in 2014 by Cécile Gueidan. The species epithet fusca refers to its characteristic dark brown areolate thallus, a feature that distinguishes it from other Willeya species.
Willeya laevigata is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Found in northwest Vietnam, it was formally described as a new species in 2014 by Cécile Gueidan. The type specimen was found growing on shaded calcareous rock outcrops in a rainforest in the Mai Châu district of Hòa Bình province. The species epithet laevigata refers to the smooth upper surface of the thallus.
Willeya protrudens is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. Found in northern Vietnam, it was formally described as a new species in 2014 by Cécile Gueidan. The type specimen was found growing on calcareous rock outcrops in the Na Hang Nature Reserve. The species epithet protrudens refers to the projecting perithecia, a morphological feature distinguishing it from other Willeya species.
Trimmatothele is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. It has five species. The genus was formally published by lichenologist Alexander Zahlbruckner in 1903. The type species, Trimmatothele perquisita, was originally collected from Norway by Johannes M. Norman, who placed it in the genus Coniothele in 1868. Diagnostic characteristics of Trimmatothele include a thin thallus with a smooth surface; small perithecia that are partially immersed in the substrata and have an involucrellum; asci that contain multiple ascospores; and small, simple ascospores. Trimmatothele has been described as one of the most poorly known genera of lichens due to the rarity of its species, the few available herbarium specimens, and some missing type specimens.
Nesothele is a genus of lichen-forming fungi in the family Verrucariaceae. It has five species. The genus was circumscribed by the British lichenologist Alan Orange in 2022, with Nesothele glebulosa assigned as the type species. This species, newly described along with the genus, is found in Nepal.
