Tetramelas is a genus of lichenized fungi in the family Caliciaceae. [1]
Aspicilia is a genus of mostly crustose areolate lichens that grow on rock. Most members have black apothecia discs that are slightly immersed in the areolas, hence the common name"Given the same reason, the naming of Aspicilia is derived from the Greek word for "shield concave".
Trapelia is a genus of lichenized fungi in the family Trapeliaceae.
Cratiria is a genus of lichen-forming fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 20 species. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000, with Cratiria lauri-cassiae assigned as the type species.
Amandinea is a genus of lichenized fungi in the family Caliciaceae. Genetic studies indicates that the genus Amandinea and Buellia are the same, although this is not widely accepted.
Dimelaena is a genus of lichenized fungi in the family Caliciaceae. Members of the genus are commonly called mountain lichens, or moonglow lichens. They are placodioid crustose lichens, ranging in form from rimose to areolate. The genus has a widespread distribution and contains eight species.
Rhizocarpon is a genus of crustose, saxicolous, lecideoid lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen.
Lepraria is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. Members of the genus are commonly called dust lichens. The main vegetative body (thallus) is made of patches of soredia. There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products are important characters to distinguish between similar species in Lepraria.
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 39 genera and about 670 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Tephromela is a genus of lichens in the family Tephromelataceae. There are about 25 species in this widespread genus.
Stereocaulon is a genus of lichens. Members of Stereocaulon are commonly called snow lichens.
Circinaria is a genus of crustose lichens in the family Megasporaceae. It was circumscribed by Johann Heinrich Friedrich Link in 1809.
Rolf Santesson (1916–2013) was a Swedish lichenologist and university lecturer. He was awarded the Acharius Medal in 1992 for his lifetime contributions to lichenology.
Leif Tibell is a Swedish lichenologist and Emeritus Professor at the University of Uppsala. He is known for his expertise on calicioid lichens. He was awarded the Acharius Medal in 2012 for lifetime achievements in lichenology.
Sculptolumina is a genus of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Sculptolumina japonica designated as the type species.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Halecania is a genus of fungi in the family Leprocaulaceae. It has 22 species. The genus was circumscribed by Austrian lichenologist Michaela Mayrhofer in 1987, with Halecania alpivaga assigned as the type species. She created Halecania to contain species, formerly placed in Lecania, with the following characteristics: uniformly amyloid apical domes, paraphyses with dark brown apical caps, and halonate ascospores.
