Austrographa is a genus of lichen-forming fungi in the family Roccellaceae. It has three species. [2] The genus was circumscribed in 2013 by lichenologists Laurens Sparrius, John Elix, and Alan Archer, with Austrographa kurriminensis assigned as the type species. [3] The genus had been published invalidly on two separate occasions. [4] [5] All three species in the genus were found in a mangrove stand in Queensland, Australia. The genus was discovered in Australia, and the name Austrographa reflects this. [4]

Description

Austrographa is a genus of crustose, corticolous (bark-dwelling) lichens, with a smooth, water-repellent thallus densely filled with fine crystals and a cortical gel. The thallus is not byssoid and lacks roccellinic acid. The photobiont of the lichen is from Trentpohlia , a genus of green algae. The ascomata are rounded to lirellate , usually aggregated in linear or rounded pseudostromata . The hyaline excipulum is made of richly branched periclinal hyphae filled with crystals, and the thalline margin is slightly paler than the thallus. The epithecium is orange to straw-colored, and the hypothecium is carbonized and dark brown. The paraphysoids are frequently branched and anastomosed, and the asci are 8-spored, cylindrical, and Opegrapha-type, with a distinct apical dome . Ascospores are acicular , hyaline, curved, and thin-walled, measuring 45–60 by 2.0–3.0  μm and contain three septa. Conidiomata were not observed in collected specimens. [4]

<span class="mw-page-title-main">Roccellaceae</span> Family of lichen-forming fungi

The Roccellaceae are a family of mostly lichen-forming fungi in the order Arthoniales, circumscribed by the French botanist François Fulgis Chevallier in 1826. Species in the family exhibit various growth forms, including crustose and fruticose thalli, and diverse reproductive structures. Roccellaceae species typically have apotheciate or lirellate ascomata, often with distinct blackened margins. Molecular phylogenetics studies have revealed significant genetic diversity and complex evolutionary histories within the family.

<i>Ochrolechia</i> Genus of lichen-forming fungi

Ochrolechia is a genus of crustose lichens in the family Ochrolechiaceae. These lichens typically form uneven, often thick, crust-like growths on various surfaces and are characterised by their white to pale grey thalli, which may have a greenish tint. The genus has a long evolutionary history, with fossils dating back to the Paleogene period, about 34 million years ago. Ochrolechia species have disc-like apothecia, which are usually yellowish or brownish-pink and often covered with a fine white powdery coating. The genus is widely distributed and includes both common and rare species, with some found in extreme environments such as arctic and alpine regions. Ochrolechia lichens produce diverse secondary metabolites, including orcinol depsides, depsidones, and xanthones.

<i>Cladia</i> Genus of lichen-forming fungi

Cladia is a genus of lichen-forming fungi in the family Cladoniaceae. Cladia species have a crustose or squamulose (scaly) primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, Cladia aggregata, is widely distributed, occurring in South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere.

<i>Sarcogyne</i> Genus of lichens

Sarcogyne is a genus of crustose lichens in the family Acarosporaceae. It was circumscribed by German botanist Julius von Flotow in 1850. A proposal has been put forth in 2021 to assign Sarcogyne clavus as the type species of the genus, "as it represents the original concept of Sarcogyne as having melanized lecideine apothecia without algae in the margin".

Septotrapelia is a genus of lichen-forming fungi in the family Pilocarpaceae. It has four species. It was validly published as a genus in 2007 by lichenologists André Aptroot and Jose-Luis Chaves.
