Verrucariales is an order of ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous (lichen-dwelling) fungi.
Frutidella is a genus of lichen-forming fungi in the family Lecanoraceae. It contains three species. The genus was circumscribed in 1994 by Klaus Kalb to contain the species formerly known as Lecidea caesioatra.
Norrlinia is a genus of two species of fungi in the family Verrucariaceae. The genus was circumscribed by Ferdinand Theissen and Hans Sydow in 1918. The genus name honours the Finnish botanist Johan Petter Norrlin. Both species are lichenicolous, meaning they parasitise lichens. The host of both fungi is the foliose genus Peltigera.
Xanthopyreniaceae is a family of lichen-forming fungi in the order Collemopsidiales. The family was circumscribed by lichenologist Alexander Zahlbruckner in 1926.
Allophoron is a fungal genus in the division Ascomycota. The relationship of this taxon to other taxa within the division is unknown, and it has not yet been placed with certainty into any class, order, or family. This is a monotypic genus, containing the single lichen species Allophoron farinosum, found in Colombia. The genus and species were described as new in 1942 by Czech lichenologist Josef Nádvorník. Allophoron has a wide distribution in tropical regions.
Antimanoa is a fungal genus in the division Ascomycota. The relationship of this taxon to other taxa within the division is unknown, and it has not yet been placed with certainty into any class, order, or family. This is a monotypic genus, containing the single species Antimanoa grisleae, originally collected from Venezuela. The genus and species were described as new to science in 1930 by German mycologist Hans Sydow.
Harpidium is a genus of lichen-forming fungi in the family Harpidiaceae. The genus contains three species. Harpidium was circumscribed in 1855 by German lichenologist Gustav Wilhelm Körber, with Harpidium rutilans assigned as the type species.
Stromatella bermudana is a saxicolous (rock-dwelling) crustose lichen. It is the only species in Stromatella, a monotypic fungal genus in the family Lichinaceae.
Hueidea is a single-species fungal genus in the family Fuscideaceae. It contains the species Hueidea australiensis, a saxicolous (rock-dwelling), crustose lichen found on granite rocks in the Mount Kosciuszko area of New South Wales, Australia. Both the species and the genus were described as new to science in 2003 by Australian lichenologists Gintaras Kantvilas and Patrick McCarthy.
Gregorella is a genus of lichenized fungi in the family Arctomiaceae. This is a monotypic genus, containing the single species Gregorella humida.
Strigulaceae is a family of lichen-forming fungi, one of two families in the order Strigulales. Recent (2020) molecular analysis of the type genus, Strigula, has led to a reallocation of the foliicolous species into six genera that correspond to well-delimited clades with diagnostic phenotype features.
Eiglera is a small genus of crustose lichens belonging to the monotypic family Eigleraceae. Eiglera species are found in Europe and Northern America.
Koerberiaceae is a small family of lichen-forming fungi in the order Peltigerales. It contains 3 genera and 9 species. The family was proposed by Toby Spribille and Lucia Muggia in 2012, after molecular phylogenetic analysis revealed the existence of three lineages of lichen-forming fungi in the suborder Peltigerineae of the order Peltigerales. The lineages represented the genera Steinera, Koerberia, and Vestergrenopsis. The latter genus was later folded into synonymy with Tingiopsidium.
Pyrenidium is a genus of lichenicolous (lichen-dwelling) fungi. It is the only genus in the family Pyrenidiaceae. It has 13 species.
Kashiwadia is a genus of lichen-forming fungi in the family Physciaceae. The genus was circumscribed in Sergey Kondratyuk, László Lőkös, and Jae-Seoun Hur in 2014 to contain the species Physcia orientalis, after molecular phylogenetic analysis showed that the taxon occupied an isolated phylogenetic position in the Physciaceae. An additional five species were added to the genus in 2021. The genus name honours Japanese lichenologist Hiroyuki Kashiwadani, who originally described the type species.
Kalbiana is a genus of saxicolous (rock-dwelling), crustose lichen of uncertain familial placement in the order Verrucariales. Both the genus and its only species, Kalbiana brasiliensis, were described in 1988 by lichenologist Aino Henssen. The genus name honours German lichenologist Klaus Kalb, while the species epithet refers to Brazil, where the lichen is found.
Isalonactis is a monotypic fungal genus in the family Roccellaceae. It contains the single species Isalonactis madagascariensis, a saxicolous (rock-dwelling), crustose lichen found in Madagascar. Both the genus and species were described as new in 2014 by Damien Ertz, Anders Tehler, Eberhard Fischer, Dorothee Killmann, Tahina Razafindrahaja, and Emmanuël Sérusiaux. The type was collected on the Isalo Massif at an altitude of 851 m (2,792 ft); there, it was found growing on sheltered mesozoic sandstone cliffs. The genus name alludes to both Isalo Massif, the type locality, and the phylogenetic relatedness to genus Lecanactis.
Timdalia is a fungal genus in the family Acarosporaceae. It is a monotypic genus, containing the single species Timdalia intricata, a saxicolous (rock-dwelling), crustose lichen. This species was first formally described by Swedish lichenologist Adolf Hugo Magnusson in 1935, based on a collection made by Eduard Frey in Austria. It was initially classified in the genus Acarospora. Josef Hafellner circumscribed Timdalia to contain the species in 2001. It was initially placed in the family Lecanoraceae, but molecular phylogenetic studies showed Timdalia to belong in the Acarosporaceae. The genus name honours Norwegian lichenologist Einar Timdal.
Tenuitholiascus is a fungal genus in the monotypic family Tenuitholiascaceae, itself in the order Strigulales. The genus contains a single species, Tenuitholiascus porinoides, a foliicolous (leaf-dwelling) lichen found in China.
Fouragea is a genus of lichen-forming fungi in the family Opegraphaceae. It has nine species.
