Buellia Lignoides
''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 (the photobiont partner) is always a member of the genus ''Trebouxia''. Lichens in the genus are commonly called disc lichens, or button lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The genus has a widespread distribution and contains about 450 species. Genetic studies indicate that the genus ''Amandinea'' and ''Buellia'' may be the same,Scheidegger, C. 2009. Amandinea Choisy ex Scheid. & H. Mayrhofer (1993). In: C. W. Smith, A. Aptroot, B. J.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buellia Spuria
''Buellia spuria'', the disc lichen, is a white to light ashy gray crustose areolate lichen that grows on rocks (epilithic) in montane habitats.Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001. Lichen Flora of the Greater Sonoran Desert Region. Vol 3/ref> It has a black edge from the conspicuous, more or less continuous prothallus, which can also be seen in the cracks between the areolas forming a hypothallus, and in sharp contrast with the whitish or ashy colored areolas. It prefers mafic (siliceous) rock substrates. In Joshua Tree National Park is can be seen on vertical granite and gneiss faces in washes.Photo Gallery, Joshua Tree Lichens, Joshua Tree National Park website, National Park Service/ref> It is common worldwide in the Northern Hemisphere.

Buellia Concinna
''Buellia concinna'', the cinnabar button lichen, is a pale yellow to greenish or brownish bullate (bubble-like) to granular crustose lichen that prefers siliceous rock and cliff faces in temperate to subarctic, subalpine and alpine climates throughout the Northern Hemisphere.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Buellia concina, Lichen Flora of the Greater Sonoran Desert Region, Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref> In North America, it prefers higher altitudes such as in the Sierra Nevada range. Lecideine apothecia are sessile on the thallus and are in diameter with black discs. Lichen spot tests are C+ orange or pinkish, K+ yellow, KC- but CK+ orange, and it is UV+ yellow to ultraviolet light.

Buellia Badia
''Buellia badia'', the parasitic button lichen, is a dark chocolate-brown crustose areolate lichen of Europe, northern Africa, and North America that starts as a parasite growing on other lichens, such as Aspicilia phaea, gradually then becoming independent growing on rock (sometimes also on hardwood.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Buellia badia, Lichen Flora of the Greater Sonoran Desert Region, Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001 Areoles may be contiguous or dispersed. Lecideine apothecia are 0.3 to 0.9 mm in diameter with black discs, that are initially flat, then become strongly convex as they age. Lichen spot tests are all negative. There are no known secondary metabolites as of (2001). It is similar in appearance and other ways to the chocolate brown '' Dimelaena californica'', which also starts off as a parasite on other lichens, and has spores of similar shape, size, and internal construction ...

Buellia Asterella
''Buellia asterella'', commonly referred to as the starry breck lichen, is a rare, black and white lichen in the family Caliciaceae. Once found all across the central European grasslands, it was described as new to science in 1974. Today, it is classified by the IUCN Red List as Critically Endangered and only found in select regions in Norway and Germany. Taxonomy This lichen was originally described by Poelt and Sulzer in 1974. There aren’t any synonyms for this species of lichen. Description ''B. asterella'' is a white and black lichen, growing on the surface of the soil where it is found. The white section of this lichen is the thallus and the black discs found on top are its fruiting structure. These black discs produce their asci, which only contain 4 spores per asci. This is very uncharacteristic for the phylum of Ascomycota as many are found with 8 spores in their asci. Their spores also do not have any internal wall thickening.

List Of Common Names Of Lichen Genera
This is a list of common names of lichen genera. When a common name for a lichen genus is the same as the scientific name for that genus, it is not included in the following list. This list only includes genera common names that are widely used, as indicated by the common name either appearing in a peer reviewed scientific publication or in a scientifically reliable reference source. A common name for a lichen genus will often uniquely refer to that genus, but not always. Sometimes the same common name may refer to several different genera, which may not be related by sharing common ancestry. An example is that " wart lichen" refers to at least five different genera in four different families. Sometimes the same genus may have more than one widely used common name. For example, members of the genus ''Staurothele'' are commonly called " wart lichens", and also "rock pimples". Lichen genus common names my come from the shape, color, or other feature of some members of a genus. Other m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photobiont
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms .
