Gyalectales

The Gyalectaceae are a family of fungi in the order Gyalectales.

Gyalecta is a genus of lichen-forming fungi in the family Gyalectaceae that contains 50 species. Gyalecta was circumscribed by lichenologist Erik Acharius in 1808. It forms associations with Trentepohlia algae.

The Phlyctidaceae are a family of lichenized fungi in the order Gyalectales. Species in this family have primarily a tropical distribution, and are usually found growing on bark.

Phlyctis is a genus of lichen-forming fungi in the order Gyalectales, and the type genus of the family Phlyctidaceae. Members of the genus are commonly called whitewash lichens. These parasitic lichens typically form very thin, patchy crusts on host surfaces or live almost entirely within their hosts, producing minute fruiting bodies that remain largely hidden beneath a coarse white . The genus is characterised by spores that are densely divided by many walls into a net-like pattern and often have tiny points at their ends. Phlyctis contains about 20 species distributed worldwide, with several

Ramonia is a genus of lichen-forming fungi in the family Gyalectaceae. Species form thin crusts on bark or rock and partner with the green alga Trentepohlia as their photosynthetic partner. They are recognized by their distinctive urn-shaped apothecia (fruiting bodies), whose inrolled rims nearly close over the spore-producing surface, leaving only a small central pore. About 22 species are accepted, found mainly in tropical and temperate regions.

Trichothelium is a genus of lichen-forming fungi in the family Porinaceae. It has an estimated 40 species. The genus was circumscribed by the Swiss lichenologist Johannes Müller Argoviensis in 1885, with Trichothelium epiphyllum assigned as the type species.

Clathroporina is a genus of lichenized fungi in the family Porinaceae. It was circumscribed by Swiss lichenologist Johannes Müller Argoviensis in 1882.

Gyalectales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 5 families, 18 genera and about 550 species.

Gallaicolichen is a fungal genus that contains the single species Gallaicolichen pacificus, a foliicolous (leaf-dwelling) lichen. Originally discovered in Hawaii in 2007, G. pacificus has since been found in various locations across the Pacific, including Australia, New Caledonia, Vanuatu, the Philippines, and Japan. The lichen forms small, pale greenish-yellow to yellowish-grey patches on leaves, typically in mid-altitude forests and along forest edges. G. pacificus is notable for its unique reproductive structures called , which produce disc-shaped propagules (peltidia) for asexual repr

Porinaceae is a family of lichen-forming fungi in the order Gyalectales. While Trichotheliaceae was proposed as an alternative, Porinaceae is the widely accepted name following ongoing nomenclatural discussions. Most members of this family typically have a crust-like appearance and grow on a variety of surfaces, including tree bark, leaves, and rocks. Porinaceae is known for its diverse morphology, ranging from simple crust-like forms to more complex structures with distinct or fan-shaped . Porinaceae species generate small, typically flask-shaped reproductive structures (), which house spores

Myeloconis is a genus of corticolous (bark-dwelling), crustose lichens in the family Porinaceae. It has four species. The genus was circumscribed in 1996 by Patrick M. McCarthy and John Elix, with M. fecunda assigned as the type species. The genus name, derived from the Greek ("marrow", or "pith") and ("dust"), refers to the powdery yellow-orange pigments in the medulla.

Pseudosagedia is a genus of corticolous (bark-dwelling) lichens in the family Porinaceae. It was first circumscribed as a section of genus Arthopyrenia by Swiss botanist Johannes Müller Argoviensis in 1862. Maurice Choisy elevated it to distinct generic status in 1949. Pseudosagedia was little used until, in 1995, Josef Hafellner and Klaus Kalb resurrected the genus to contain members of the Porina nitidula species group with the perithecial pigment called Pseudosagedia-violet and lacking setae.

Semigyalecta is a genus of lichenized fungi in the family Gyalectaceae. It is a monotypic genus, containing the single species Semigyalecta paradoxa, described as new to science in 1921 by Finnish lichenologist Edvard August Vainio.
