Haematomma is a genus of crustose lichens established by Abramo Bartolommeo Massalongo in 1852. [2] It is the sole genus in the Haematommataceae, [3] a family circumscribed by Josef Hafellner in 1984. [4] Commonly called bloodstain lichens, [5] the species assigned to this genus are widely distributed in tropical and temperate areas. [6]
The genus name Haematomma means "bloody eye", a reference to the color of the lichen's apothecia. [7]
As of September 2021 [update] , Species Fungorum accepts 22 species in the genus Haematomma: [8]
Usnea is a genus of mostly pale grayish-green fruticose lichens that grow like leafless mini-shrubs or tassels anchored on bark or twigs. The genus is in the family Parmeliaceae. It grows all over the world. Members of the genus are commonly called old man's beard, beard lichen, or beard moss.
Biatorellaceae is a family of lichen-forming fungi in the subclass Lecanoromycetidae. The family is monotypic, and contains the single genus Biatorella, which contains eight species.
Pseudevernia is a genus of foliose lichens in the family Parmeliaceae. The type species of the genus, Pseudevernia furfuracea, has substantial commercial value in the perfume industry.
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.
Ochrolechia is a genus of crustose lichens in the family Ochrolechiaceae.
Diorygma is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Franz Gerhard Eschweiler in 1824. Species of the genus are widely distributed in tropical and subtropical regions of the world.
Toninia is a genus of lichen-forming fungi in the family Ramalinaceae.
Teloschistes is a genus of lichens in the family Teloschistaceae, of which it is the namesake. It was circumscribed by Norwegian botanist Johannes Musaeus Norman in 1852. The name of the genus means "split ends".
Bactrospora is a genus of lichen-forming fungi of uncertain familial placement in the order Arthoniales. It was circumscribed by Abramo Bartolommeo Massalongo in 1852.
Mazosia is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1854.
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.
Arthopyrenia is a genus of fungi in the family Trypetheliaceae. It was formerly classified in the eponymic family Arthopyreniaceae, but molecular phylogenetics studies showed that the type species, Arthopyrenia cerasi, was a member of the Trypetheliaceae.
Haematomma ochroleucum, also known as yellow bloodstain lichen, is a species of crustose lichenized fungus. First described in 1771 by Noël Martin Joseph de Necker, it has no subspecies, but two named varieties: H. o. var. ochroleucum and H. o. var. porphyrium.
Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
Melaspilea is a genus of lichen-forming and lichenicolous fungi in the family Melaspileaceae. The genus was circumscribed by Finnish lichenologist William Nylander in 1857.
Solenopsora is a genus of lichen-forming fungi in the family Catillariaceae. It has 15 species, with a mostly Northern Hemisphere distribution.
Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. It has 13 species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852, with Loxospora elatina assigned as the type species. This crustose lichen was originally named Lecanora elatina by Erik Acharius in 1810.
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.
Piccolia is a small genus of crustose lichens in the class Lecanoromycetes. First circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1864, it contains ten species. Due to a lack of molecular data, it has not been assigned to an order or family.
