The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution. [4]
Lecanoraceae was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855. [5]
According to a 2024 estimate, Lecanoraceae contains about 715 species distributed amongst 26 genera. [6]
The Arthoniales is the second largest order of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species.
The Lecanorales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The order contains 26 families, 269 genera, and 5695 species.
The Ramalinaceae are a family of lichen-forming fungi in the order Lecanorales. First proposed by Carl Adolph Agardh in 1821, the family now comprises 63 genera and about 750 species. Ramalinaceae lichens exhibit diverse growth forms, including crustose, fruticose, squamulose, leprose, and byssoid thalli, and form symbiotic relationships primarily with green algae of the genus Trebouxia. The family is characterised by pale-coloured thalli, apothecia that are typically pale but may darken with age, and ascospores that vary in shape and septation.
The Physciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. A 2016 estimate placed 19 genera and 601 species in the family.
The Baeomycetales are an order of mostly lichen-forming fungi in the subclass Ostropomycetidae, in the class Lecanoromycetes. It contains 8 families, 33 genera and about 170 species. As a result of molecular phylogenetics research published in the late 2010s, several orders were folded into the Baeomycetales, resulting in a substantial increase in the number of taxa.
Schadonia is a genus of lichen-forming fungi. Established by German lichenologist Gustav Wilhelm Körber in 1859, this genus of crustose lichens is characterised by its black, sessile apothecia, muriform ascospores, and growth on mosses, plant debris, and rocks in montane habitats. While traditionally placed in the family Ramalinaceae, recent studies have suggested its classification may be uncertain within the order Lecanorales, with some researchers proposing its placement in the Pilocarpaceae or the resurrection of the family Schadoniaceae. The genus currently comprises four recognised species.
Lecidella is a genus of crustose lichens in the family Lecanoraceae.
Pyrrhospora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with Pyrrhospora quernea assigned as the type species.
Candelariaceae is a family of lichen-forming fungi in the order Candelariales. It contains seven genera and about 73 species.
Absconditella is a genus of lichen-forming fungi in the family Stictidaceae. These lichens are characterised by their inconspicuous growth and small, cup-shaped fruiting bodies (apothecia) that are often hidden within a jelly-like mass containing green algae. The genus name, meaning "hidden", reflects their elusive nature. Absconditella species are typically found on short-lived surfaces such as decaying wood, mosses, and unstable soil. Genetic studies have revealed that the genus is more complex than previously thought, with some species being moved to a new genus, Absconditonia, and others potentially representing groups of closely related species. Despite their small size and easily overlooked nature, environmental DNA studies suggest that Absconditella lichens may be more widespread than collections indicate.
The Lecideaceae are a family of lichen-forming fungi in the order Lecideales. It contains about 30 genera and roughly 250 species. A major distinguishing characteristic of the family is the lecanoroid form of the fruiting bodies: typically circular, dark, and without a thalline margin. Most species in the family are lichenised with green algae, although a few species, scattered amongst several genera, are lichenicolous—they live on other lichens. Lecideaceae lichens tend to grow on rocks, wood, and soil. Several Lecideaceae species accelerate the weathering of rock surfaces, a process known as pedogenesis, by extending their hyphae into cracks and expelling rock flakes. This contributes to significantly faster weathering rates in certain environments, impacts various materials from natural rocks to man-made Sekishu roof tiles, and involves key biomolecules identified for survival and biodeterioration, including compounds to withstand intense ultraviolet radiation.
Fuscidea is a genus of crustose lichens in the family Fuscideaceae. It has about 40 species. The genus was circumscribed in 1972 by lichenologists Volkmar Wirth and Antonín Vězda, with Fuscidea aggregatilis assigned as the type species.
Palicella is a genus of crustose lichens in the family Lecanoraceae. It contains six species.
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species.
Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".
Trapeliaceae is a family of lichens in the order Baeomycetales. The family contains 12 genera and about 125 species.
Schaereria is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes. Most Schaereria species are crustose lichens that live on rocks. Schaereria was first proposed by Gustav Wilhelm Körber in 1855 and was later taken up by other lichenologists despite periods of disuse.
Xanthopsorella is a fungal genus in the family Catillariaceae. It comprises the single species Xanthopsorella texana, a saxicolous (rock-dwelling), squamulose lichen found in the Southern United States and Mexico.
Straminella is a genus of lichen-forming fungi in the family Lecanoraceae. It comprises seven species.
