Peltigerales
Peltigerales is an order (biology), order of lichen-forming fungus, fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (mycology), division Ascomycota. The taxonomy of the group has seen numerous changes; it was formerly often treated as a suborder of the order Lecanorales. It contains two suborders, eight family (biology), families and about 45 genus, genera such as ''Lobaria'' and ''Peltigera''. The fungi form lichens in a symbiosis, symbiotic relationship with one or two photosynthesis, photosynthetic partners which may be a cyanobacterium such as ''Nostoc'' or a green alga such as ''Coccomyxa''. The majority of species contain just a cyanobacterium, a smaller number have both a cyanobacterium and a green alga while only a few species have just a green alga. The thallus of the lichen may be foliose (leafy), subfruticose (somewhat shrubby) or granular-squamulose (scaly). The thallus attaches to a surface by means of small root-like rhizines. In some s ...

Collematineae
The Collematineae are an suborder of rust fungi in the order of Peltigerales in the class Lecanoromycetes.David J. McLaughlin and Joseph W. Spatafora (Editors) It contains 5 family (biology), families, the Coccocarpiaceae, the Collemataceae, the Pannariaceae, the Placynthiaceae and also the Vahliellaceae. History It was set up in 2004 to contain 4 families, the Coccocarpiaceae, the Collemataceae, the Pannariaceae and the Placynthiaceae by Miadlikowska & Lutzoni. The new suborder was agreed by Hibbet et al, in 2007 and Lumbsch and Huhndorf in 2007, and 2010. The other Peltigerales based suborder of Peltigerineae contained 6 families; Koerberiaceae, Lobariaceae, Massalongiaceae, Nephromataceae, Peltigeraceae and Vahliellaceae, also by Miadlikowska & Lutzoni in 2004. Vahliellaceae is still sometimes placed within the Peltigerineae suborder. A molecular phylogenetic study of the Collemataceae was carried out in 2010. It found that Ascus#Ascospores, ascospore characteristics are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vahliellaceae
''Vahliella'' is a genus of nine species of lichen-forming fungi in the order Peltigerales. It is the only member of Vahliellaceae, a family circumscribed in 2010 to contain this genus. ''Vahliella'' was formerly placed in the family Pannariaceae until molecular phylogenetics showed that it did not belong there. ''Vahliella'' species are found in the Northern Hemisphere – mainly in North America, but also in Europe and India. ''Vahliella'' species somewhat resemble those of the genus '' Fuscopannaria'' – in which they were originally classified – but are distinguished from them by the layered apical amyloid sheets of the asci, the lack of lichen substances, and the absence of an epispore. Taxonomy ''Vahliella'' was circumscribed by Norwegian botanist Per Magnus Jørgensen in 2008. It was created to contain species formerly placed in the subgenus ''Micropannaria'' of '' Fuscopannaria'', a genus erected by Jørgensen in 1994. ''Micropannaria'' contained two species that ...

Massalongiaceae
''Massalongiaceae'' is a small family of lichen-forming fungi in the order Peltigerales. It has three genera and seven species. Species in this family have cyanobacteria as their primary symbiotic partner ( cyanobiont), so they belong to the group known as "cyanobacterial lichens". Taxonomy The family was circumscribed by Mats Wedin, Per Magnus Jørgensen, and Elisabeth Wiklund in 2007. Molecular phylogenetic analysis showed that the three genera formed a well-supported monophyletic group that was distinct from other similar families in the Peltigerales. The family was named after the type genus, '' Massalongia''; the genus name honours Italian lichenologist Abramo Bartolommeo Massalongo (1824-1860). Massalongiaceae has a sister taxon relationship with the family Peltigeraceae, and these two families together form a clade that is sister to a clade containing the families Vahiellaceae and Koerberiaceae. Previous phylogenetic studies had placed genus ''Massalongia'' in a group t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koerberiaceae
Koerberiaceae is a small family (biology), family of lichen-forming fungi in the order Peltigerales. It contains 3 genus, genera and 9 species. The family was proposed by Toby Spribille and Lucia Muggia in 2012, after molecular phylogenetic analysis revealed the existence of three lineage (evolution), lineages of lichen-forming fungi in the suborder Peltigerineae of the order Peltigerales. The lineages represented the genera ''Steinera'', ''Koerberia'' (the type genus of the family), and ''Vestergrenopsis''. The latter genus was later folded into synonym (biology), synonymy with ''Tingiopsidium''. ''Steinera'', circumscribed by Alexander Zahlbruckner in 1906, was previously classified in family Koerberiaceae, but the genus and many of its species were transferred to the family Arctomiaceae in 2017, and a new genus ''Henssenia'' was created to contain the remaining species. Description Members of the Koerberiaceae have thallus, thalli that are squamulose lichen, squamulose (scaley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peltigera
''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of ''Peltigera'' are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other in many parts of the world. Most species of ''Peltigera'' have the cyanobacterium ''Nostoc'' as the dominant photobiont but some have the algae '' Coccomyxa.'' The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, ''Nostoc''. Because of their ability to fix nitrogen from the atmosphere, such lichens are influential in soil composition and generation. Description Species of ''Peltigera'' are foliose, with broad lobed thalli. Although the size of the thalli is variable and species-dependent, in some species the thalli can grow quite large, up to 30 cm in diameter.Vitikainen O. (1994). (1998). Taxonomic notes on n ...

Peltigeraceae
The Peltigeraceae are a family of lichens in the order Peltigerales. The Peltigeraceae, which contains 15 genera and about 600 species, has recently (2018) been emended to include the families Lobariaceae and Nephromataceae. Many Peltigeraceae species have large and conspicuous, leathery thalli. They largely occur in cool-temperate to tropical montane climates. Tripartite thalli involving fungus, green algae and cyanobacteria are common in this family. Taxonomy The family Peltigeraceae was circumscribed by Belgian botanist Barthélemy Charles Joseph Dumortier in 1822. Using a temporal approach that uses time-calibrated chronograms to identify and define temporal bands for comparable ordinal and family ranks in the Lecanoromycetes, the families Lobariaceae and Nephromataceae were synonymized with Peltigeraceae in 2018. In a later critical review of the use of this method for the biological classification of lichens, Robert Lücking considered this merge justified based on severa ...

Collemataceae
The Collemataceae are a family of mostly lichen-forming fungi in the order Peltigerales. The family contains twelve genera and about 325 species. The family has a widespread distribution. Taxonomy The family was circumscribed by Jonathan Carl Zenker in 1827; ''Collema'' is the type genus. Description Collemataceae members have a thallus that is either foliose, crustose, squamulose or minutely shrubby. The thallus is gelatinous, sometimes swelling when wet, with a colour ranging from dark olive-green to brown-black, reddish brown or rarely grey-blue. The upper and lower cortex is either absent or composed of angular brick-like cells, more rarely of flattened compressed cells. The medulla contains loosely interwoven narrow hyphae or is compact with broad-short-celled hyphae; these hyphae are intermixed with the photobiont. The texture of the upper cortex surface ranges from smooth to wrinkled or ridged, and is often glossy, but rarely arachnoid. The underside of the cortex is s ...

Lobaria
''Lobaria'' is a genus of foliose lichens, formerly classified in the family Lobariaceae, but now placed in the Peltigeraceae. They are commonly known as "lung wort" or "lungmoss" as their physical shape somewhat resembles a lung, and their ecological niche is similar to that of moss. ''Lobaria'' are unusual in that they have a three-part symbiosis, containing a fungus, and an alga (as other lichens do), but also a cyanobacterium that fixes nitrogen. Taxonomy ''Lobaria'' was originally described as a section of the eponymous genus ''Lichen'' by German naturalist Johann Christian Daniel von Schreber in 1786. It was proposed as a genus by Georg Franz Hoffmann in 1796. The establishment of ''Lobaria'' remained uncertain until Edvard Vainio also described it. He divided the genus into two sections based on different morphologies of the mature spore: ''Lobaria'' and ''Ricasolia''. In 2013, the concept of family Lobariaceae was revised with the help of molecular phylogenetics, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
