genus of fungi

Diploschistes is a genus of lichen-forming fungi in the family Graphidaceae. Commonly known as crater lichens, members of the genus are crustose lichens with a thick, cracked (areolate) body (thallus) with worldwide distribution. The fruiting part (apothecia) are immersed in the thick thallus so as to have the appearance of being small "craters". The widespread genus contains about 43 species.

Gyalidea is a genus of crustose lichens in the family Gomphillaceae. It has 50 species.

Thelotrema is a genus of lichen-forming fungi in the family Graphidaceae, the family to which all taxa in the former Thelotremataceae now belong.

Gyalectidium is a genus of lichen-forming fungi in the family Gomphillaceae. Established in 1881 by Swiss lichenologist Johannes Müller Argoviensis, the genus comprises about 50 species of predominantly leaf-dwelling lichens that form small, pale greenish to whitish-grey patches typically only a few millimetres across. Members are characterised by specialised asexual reproductive structures called , which are small scale-like outgrowths that produce propagules containing both fungal and algal partners, and by fruiting bodies that contain single, large, multi-chambered ascospores. The genus has

Gymnographa is a genus of lichen-forming fungi in the family Graphidaceae. It contains two species.

Jamesiella is a genus of lichen-forming fungi in the family Gomphillaceae. Members of Jamesiella form thin, delicate crusts on tree bark, rocks, and mosses in humid tropical and temperate forests, distributed across North and South America and Europe. The genus is distinguished from its close relative Gyalideopsis by a unique type of asexual reproductive structure called , which are specialized stalks containing both fungal filaments and algal cells that detach and disperse as complete units capable of establishing new lichens.

Asterothyrium is a genus of leaf-dwelling lichens in the family Gomphillaceae. These tiny lichens form small, star-shaped fruiting bodies on the surface of leaves in tropical and subtropical forests. They are most commonly found in humid, shaded environments where leaves remain moist and clean. The genus includes 19 recognised species distributed primarily throughout Central and South America.

Gyalideopsis is a genus of lichen-forming fungi in the family Gomphillaceae. Gyalideopsis species form delicate, film-like crusts on a wide variety of surfaces including tree bark, rocks, and mosses, often in tropical and temperate forests worldwide. Species in the genus produce distinctive small, scale-like structures called , which are thought to aid in asexual reproduction where ascospore-producing structures are absent or uncommon. Members of this genus lack the distinctive chemical compounds found in many other lichens, making them reliant on microscopic features and spore characteristics

The type species of the genus is P. caesiopruinosa. These bark-dwelling lichens are found in moist, shaded forests across tropical and warm temperate regions worldwide, where they form pale crusts that develop distinctive flattened, plate-like fruiting structures. A combination of several features characterizes Platygramme: the brown ascospores, a spore-producing layer (hymenium) speckled with granules, and elonga

Species of Aulaxina are found predominantly in humid tropical forests across Africa, Asia, and the Americas, where they grow on the surface of living leaves, a foliicolous lifestyle. The genus is recognised by its distinctive blackish fruiting bodies, which open in a star-like or slit-like pattern, and by the small dark hairs and club-shaped reproductive structures that dot the thallus surface. The exact number of species in the genus is uncertain, as different taxonomic databases currently disagree on which names are acc

Stegobolus is a genus of lichen-forming fungi in the family Graphidaceae. Established in 1845 by the French botanist Camille Montagne, the genus contains 16 species distinguished by their unique fruiting structures that initially appear drum-shaped and closed, later bursting open by shedding their roof-like covering. These bark-dwelling lichens are found in humid tropical and warm temperate forests worldwide, where they serve as indicators of undisturbed woodland habitats due to their sensitivity to canopy opening and drought.

Established in 1853 by the Italian botanist Vittore Trevisan de Saint-Léon, the genus comprises 20 species distinguished by their narrow script-like slits immersed in a pale crusty surface, often with dark brown or occasionally crimson-dusted fruiting structures. Found throughout tropical regions from sea level to mountain forests above 3,000 metres, these bark-dwelling lichens are more tolerant of light and moisture variation than many related species, allowing them to colonise forest edges and moderately sun-exposed lo

Species of the genus are widely distributed in tropical and subtropical regions of the world. These lichens form paint-like crusts on bark and rock that range from chalky white to light green, with elongated, pencil-like slits containing their spores that may flex and branch across the surface. The genus was established in 1824 for tropical script lichens with large, many-celled spores, but molecular studies in the 2000s and 2010s expanded it significantly by

Described in 2002 by the German lichenologist Bettina Staiger, these bark-dwelling lichens are found in humid, shaded forests across tropical and warm temperate regions worldwide. They are characterized by their flattened, plate-like fruiting structures with completely blackened walls and are sensitive to forest disturbance, making their presence an indicator of long-established woodland conditions.

Actinoplaca is a small genus of lichen-forming fungi in the family Gomphillaceae. The genus is foliicolous, meaning its species grow on the surface of living leaves in humid tropical forests, and has been recorded from Central and South America and tropical Africa.

Anomomorpha is a genus of lichens in the family Graphidaceae. The genus, described in 1891, has a pantropical distribution. These lichens form pale grey to dull olive crusts on tree bark that often develop low wart-like bumps covered with powdery particles, and produce narrow, usually wavy slit-like fruiting bodies. They are found in tropical rainforests worldwide, growing on shaded to semi-exposed bark in primary or lightly disturbed evergreen forests, with some species being narrowly restricted to specific mountain cloud forests.

Originally established in 1961 for a single species from Brazil, the genus was later expanded to include many species previously classified in the related genus Tricharia, all sharing distinctive white bristle-like structures and flattened fruiting bodies. Recent molecular studies suggest that Aderkomyces as currently defined may not represent a natural evolutionary group, leading to ongoing reclassification of many species into other genera.
