Lasallia is a genus of lichenized fungi in the family Umbilicariaceae.
The genus name of Lasallia is in honour of Mr. Lasalle (around 1820), who was a French gardener and botanist, who worked in Fontainebleau. [1]
It was circumscribed by François Victor Mérat de Vaumartoise in Nouv. Fl. Paris ed.2, vol.1 on page 202 in 1821.
The genus contains 12 species with a widespread, but predominantly temperate distribution. [2] Phylogenetic analysis of internal transcribed spacer DNA has shown that the genus is monophyletic. [3]
High performance liquid chromatography analysis of eleven Lasallia species revealed a number of secondary metabolites in this genus, including gyrophoric acid, lecanoric acid, umbilicaric acid, 7-chloroemodin, valsarin, skyrin, hiascic acid, and ovoic acid. [4]
Parmelia is a genus of medium to large foliose lichens. It has a global distribution, extending from the Arctic to the Antarctic continent but concentrated in temperate regions. There are about 40 species in Parmelia. In recent decades, the once large genus Parmelia has been divided into a number of smaller genera according to thallus morphology and phylogenetic relatedness.
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.
Geomyces is a genus of filamentous fungi in the family Myxotrichaceae. Members of the genus are widespread in distribution, especially in northern temperate regions. Known to be psychrotolerant and associated with Arctic permafrost soils, they are equally prevalent in the air of domestic dwellings, and children's sandpits. Species of Geomyces have previously been placed in the genus Chrysosporium.
Disciotis is a genus of fungi in the family Morchellaceae. Members of this family, characterized by their cup- or bowl-shaped apothecia, have a widespread distribution, especially in northern temperate regions.
Dothideales are an order of bitunicate fungi consisting mainly of saprobic or plant parasitic species.
The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
An isidium is a vegetative reproductive structure present in some lichens. Isidia are outgrowths of the thallus surface, and are corticated, usually with a columnar structure, and consisting of both fungal hyphae and algal cells. They are fragile structures and may break off and be distributed by wind, animals, and splashing raindrops. In terms of structure, isidia may be described as warty, cylindrical, clavate (club-shaped), scale-like, coralloid (coral-shaped), simple, or branched.
The Inocybaceae are a family of fungi in the order Agaricales, the largest order of mushroom-forming fungi. It is one of the larger families within Agaricales. This family exhibits an ectomycorrhizal ecology. Members of this family have a widespread distribution in tropical and temperate areas.
The Acarosporaceae are a family of fungi in the order Acarosporales. Members of this family have a widespread distribution, and are mostly lichenized with green algae. According to a 2021 estimate, the family contains 11 genera and about 260 species. The family is characterised by a hamathecium formed of paraphysoids.
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.
The Coniochaetales are an order of fungi within the class Sordariomycetes. This order was monotypic and contained a single family, the Coniochaetaceae, historically placed in the order Sordariales. However, this taxonomic placement has been challenged by other authorities, and the Coniochaetales was proposed to include the family Coniochaetaceae. In 2020, family Cordanaceae was added to the order.
Tuckermannopsis is a genus of foliose lichens in the family Parmeliaceae.
Astraeus is a genus of fungi in the family Diplocystaceae. The genus, which has a cosmopolitan distribution, contains nine species of earthstar mushroom. They are distinguished by the outer layer of flesh (exoperidium) that at maturity splits open in a star-shape manner to reveal a round spore sac. Additionally, they have a strongly hygroscopic character—the rays will open when moist, but when hot and dry will close to protect the spore sac. Species of Astraeus grow on the ground in ectomycorrhizal associations with trees and shrubs. Despite their similar appearance to the Geastrum earthstars Astraeus is not closely related.
The Umbilicariales are an order of lichenized fungi in the subclass Umbilicariomycetidae, class Lecanoromycetes. It contains five families: Elixiaceae, Fuscideaceae, Ophioparmaceae, Ropalosporaceae, and Umbilicariaceae. Umbilicariales was proposed as a new order in 2007, while the subclass Umbilicariomycetidae was proposed in 2013.
Architrypethelium is a genus of lichen-forming fungi in the family Trypetheliaceae. The genus was circumscribed in 1991 by Dutch lichenologist André Aptroot, with A. seminudum assigned as the type species. It is a segregate of genus Trypethelium.
Phacopsis is a genus of lichenicolous (lichen-dwelling) fungi. They are parasites of members of the large lichen family Parmeliaceae, of which they are also a member. Originally proposed by Edmond Tulasne in 1852 to contain 3 species, Phacopsis now contains 10 species, although historically, 33 taxa have been described in the genus. Many of the species are poorly known, some of them having been documented only from the type specimen.
The Magnaporthales are an order of fungi within the class Sordariomycetes and subclass Diaporthomycetidae. It has several water based species and genera.
Neoprotoparmelia is a genus of crustose lichens that was created in 2018. It contains 24 tropical and subtropical species that mostly grow on bark. Neoprotoparmelia is in the subfamily Protoparmelioideae of the family Parmeliaceae, along with the morphologically similar genera Protoparmelia and Maronina.
Robert Lücking is a German lichenologist. He earned his master's and PhD from the University of Ulm, focusing on the taxonomy, ecology, and biodiversity of foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in The Bryologist. Since 2015, he has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum, and several lichen species and a genus have been named in his honour.
Graphidales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 families, about 81 genera and about 2,228 species. Family Graphidaceae are the largest crustose family within Graphidales order comprising more than 2000 species, which are widely distributed in tropical and subtropical regions of the world.
