Calicium viride Pers. (1794) | |
Calicium viride, commonly known as the green stubble lichen, is a species of pin lichen in the family Caliciaceae, and the type species of the genus Calicium . It is a common and widely distributed species in temperate areas of the Northern Hemisphere and southern South America.
It was described as a new species by Christiaan Hendrik Persoon in 1794. [1] Calcium viride is the type species of the genus Calicium . The common name for the lichen in North America is "green stubble lichen". [2]
The Calicium viride group is the name of a clade of closely related species that all have ascomata supported on relatively large and sturdy stalks, and spores with a distinctive spiral ornamentation. This group also includes C. corynellum , C. salicinum , and C. quercinum , as well as Cyphelium lecideinum , which lacks a stalk but also has spiral-striated spores. [3]
Calicium viride has a greenish-yellow thallus with a granular texture that grows as a crust on the surface of its substrate. The small black stalks, 1.5–2.5 mm long and roughly 0.1–0.15 mm thick, support the spore-bearing structures: at the tip of each stalk is a capitulum–a spherical apothecium. The capitula are black with a brownish underside. [2]
Calicium corynellum is a rarer species that is somewhat similar in appearance to C. viride, but it grows on rock instead of wood or bark, and it has shorter stalks, typically 0.5–0.6 mm long. [4]
It contains the secondary chemicals rhizocarpic acid and epanorin. [2]
The lichen is common on the bark and wood of conifer trees in montane forests, but sometimes grows on deciduous trees. [2]
Calicium is a genus of leprose lichen lichens. It is in the family Caliciaceae.
Buellia is a genus of mostly lichen-forming fungi in the family Caliciaceae. The fungi are usually part of a crustose lichen. In this case, the lichen species is given the same name as the fungus. But members may also grow as parasites on lichens (lichenicolous). The algae in the lichen is always a member of the genus Trebouxia.
Cyphelium tigillare is a species of lignicolous (wood-dwelling) lichen in the family Caliciaceae, and the type species of the genus Cyphelium. Widespread in North America, it commonly grows on fenceposts.
Nephroma is a genus of medium to large foliose lichens. The genus has a widespread distribution. They are sometimes called kidney lichens, named after the characteristic kidney-shaped apothecia that they produce on the lower surface of their lobe tips, which often curl upwards and thus are visible from above. Sterile specimens that do not have apothecia can look somewhat like Melanelia, Peltigera, Platismatia, or Asahinea. Most species grow either on mossy ground or rocks, or on trees.
Imshaugia is a genus of seven species of foliose lichens in the family Parmeliaceae. They are commonly known as starburst lichens.
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 36 genera and about 600 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Pilophorus acicularis, commonly known as the nail lichen or the devil's matchstick lichen, is a species of matchstick lichen in the family Cladoniaceae.
Peniophora quercina is a species of wood-decay fungus in the family Peniophoraceae. It produces fruit bodies that vary in appearance depending on whether they are wet or dry. The wet fruit bodies are waxy and lilac, and attached strongly to the wood on which they grow. When dry, the edges curl up and reveal the dark underside, while the surface becomes crusty and pink. P. quercina is the type species of the genus Peniophora, with the species being reclassified as a member of the genus upon the latter's creation by Mordecai Cubitt Cooke. P. quercina is found primarily in Europe, where it can be encountered all year. Though primarily growing upon dead wood, especially oak, it is also capable of growing upon still-living wood.
Calicium sequoiae is a crustose lichen that has only been found growing on old-growth redwood trees in California. It is a species of pin lichen in the family Caliciaceae. Apothecia are white-powder coated (pruinose). The unusual spores have spiral ridges.
Psilolechia lucida is a species of saxicolous lichen in the family Psilolechiaceae. It is widely distributed through the world, where it grows on natural and artificial rocky substrates in the shade, often in sheltered underhangs. It forms a greenish crust on the surface of its substrate.
Cladonia caespiticia is a widespread and common species of fruticose, cup lichen in the family Cladoniaceae. It was originally named Baeomyces caespiticius by German mycologist Christiaan Hendrik Persoon in 1794. Heinrich Gustav Flörke transferred it to the genus Cladonia in 1827. In North America, it is commonly known as the stubby-stalked Cladonia.
Allocalicium is a lichen genus in the family Caliciaceae. It is monotypic, containing the single pin lichen species Allocalicium adaequatum.
Pyxine sorediata, commonly known as mustard lichen, is a widely distributed species of foliose lichen in the family Caliciaceae. It has a subtropical to warm temperate distribution, and grows on bark, rocks, and moss as substrates. Pyxine sorediata has been reported from regions of North America, Europe, Africa, Asia, and Australasia.
Melanohalea subolivacea, commonly known as the brown-eyed camouflage lichen, is a species of foliose lichen in the family Parmeliaceae.
Calicium trabinellum, commonly known as the yellow-collar stubble lichen, is a widespread species of pin lichen in the family Caliciaceae. It was first described by Swedish lichenologist Erik Acharius in 1803 as Calicium xylonellum ß trabinellum. He made the new combination Calicium trabinellum in a later chapter of the same publication.
Umbilicaria hyperborea, commonly known as blistered rock tripe, is a species of foliose lichen in the family Umbilicariaceae. It is widely distributed in arctic and alpine regions.
Punctelia hypoleucites, commonly known as the southwestern speckled shield lichen, is a species of foliose (leafy) lichen in the family Parmeliaceae. First formally described by Finnish botanist William Nylander as a species of Parmelia, it was transferred to the genus Punctelia in 1982. The lichen is found in Africa, North America, and South America, where it grows on the bark of both hardwood and coniferous trees. Its greenish-grey thallus is covered with tiny white pseudocyphellae – minute holes in the thallus surface that facilitate gas exchange. Some macroscopic features that help distinguish this species from other related members of the genus include the presence and the structure of the apothecia, the absence of asexual surface propagules, and the light brown color of the thallus undersurface. Chemically, the presence of lecanoric acid in the medulla and atranorin in the cortex help distinguish it from lookalikes.
Punctelia graminicola is a species of foliose (leafy) lichen in the family Parmeliaceae. It grows on rocks, and, less frequently, on bark in North America, South America, and East Africa. It has a blue-grey thallus measuring up to about 15 cm (6 in), covered with tiny pores called pseudocyphellae. Sometimes the lichen forms small lobes that project out from the surface. Fruiting bodies are uncommon in this species; if present, they resemble small cups with a brown internal disc measuring 3–10 mm (0.1–0.4 in) in diameter. A lookalike species, Punctelia hypoleucites, is not readily distinguishable from Punctelia graminicola by appearance or habitat alone; these species can only be reliably differentiated by examining the length of their conidia.
Mycocalicium enterographicola is a species of lichenicolous fungus in the family Mycocaliciaceae. It is found in Brazil.
Calicium pinicola is a species of lignicolous (wood-dwelling), crustose lichen in the family Caliciaceae. It is widely distributed in Europe, and also occurs in the United States.
