Caloplaca Furax
''Kuettlingeria furax'' is a species of lichenicolous (lichen-dwelling) crustose lichen in the family Teloschistaceae. It was first formally described as a new species in 1983 by José María Egea Fernández and Xavier Llimona; they classified it in the genus ''Caloplaca''. The type specimen of this lichen was discovered in the eastern part of the Sierra Morena mountains in Albacete, Spain. It was found growing parasitically on other lichens in the genus ''Aspicilia'', which are found on silica-rich surfaces. ''Kuettlingeria furax'' appears as small, circular patches that are a deep brownish-grey colour. It has a somewhat lobed edge, and its reproductive structures ( apothecia), quickly lose their . The authors compared it to '' Caloplaca conglomerata'', but noted the distinctness of its spores, which are broader and have a bulged middle. The taxon was transferred to the genus '' Kuettlingeria'' in 2020; it has also been proposed for inclusion in the genus ''Pisutiella ...

Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear molecule.

Teloschistales
The Teloschistales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. According to one 2008 estimate, the order contains 5 families, 66 genera, and 1954 species. The predominant photobiont partners for the Teloschistales are green algae from the genera ''Trebouxia'' and '' Asterochloris''. Families *Brigantiaeaceae The Brigantiaeaceae are a family of fungi in the order Teloschistales.

Species Fungorum
''Index Fungorum'' is an international project to index all formal names ( scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and '' Fungal Names''. Current names in ''Index Fungorum'' (''Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pisutiella
''Pisutiella'' is a genus of lichen-forming fungi in the family Teloschistaceae. It contains five species of saxicolous lichen, saxicolous (rock-dwelling), crustose lichens that are found in a variety of environments in the Northern Hemisphere. Taxonomy The genus was circumscription (taxonomy), circumscribed in 2020 by lichenologists Sergey Kondratyuk, László Lőkös, and Edit Farkas, with ''Pisutiella conversa'' assigned as the type species. This species was originally described in 1861 by August von Krempelhuber as ''Callopisma conversum'', and was later known as a member of the large genus ''Caloplaca''. The genus name was chosen by the authors to honour the Slovak lichenologist Ivan Pišút (1935–2017), "to acknowledge his great contribution to our knowledge on lichens of the Carpathians and in recognition of his general contribution to lichenology". ''Pisutiella'' is in the subfamily Caloplacoideae of the family Teloschistaceae. Description The lichen genus ''Pisutiell ...

Kuettlingeria
''Kuettlingeria'' is a genus of saxicolous lichen, saxicolous (rock-dwelling), crustose lichens in the family Teloschistaceae. Species are characterized by a white or gray thallus and the presence of anthraquinones in the apothecial and , with the exception of ''Kuettlingeria diphyodes'', which entirely lacks anthraquinones. First described by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon, Trevisan in 1857, the genus includes 15 recognized species, although it is believed to be more diverse with additional unnamed species. These lichens are predominantly found in the Northern Hemisphere, particularly in the Mediterranean Basin, Mediterranean region, and grow on limestone and base-rich siliceous outcrops in sunlit conditions. Taxonomy The lichen genus ''Kuettlingeria'' was first described by Vittore Benedetto Antonio Trevisan de Saint-Léon in 1857. The type species is ''Kuettlingeria visianica'', which was previously known as ''Blastenia visianica'' and origi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxon
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caloplaca Conglomerata
''Caloplaca'' is a lichen genus comprising a number of distinct species. Members of the genus are commonly called firedot lichen, jewel lichen.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, gold lichens, "orange lichens", but they are not always orange, as in the case of '' C. albovariegata''. The distribution of this lichen genus is worldwide, extending from Antarctica to the high Arctic. It includes a portion of northern North America and the Russian High Arctic. There are about thirty species of ''Caloplaca'' in the flora of the British Isles. An example species in this genus is '' Caloplaca saxicola'', a lichen with worldwide distribution including the Antarctic continent, Europe and northern North America including the northern reaches of the Canadian boreal forests. A new species of ''Caloplaca'', '' C. obamae'', the first species to be named in honor of Barack Obama, was discovered in 2007 on Santa Rosa Island in California and ...

Apothecia
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspicilia
''Aspicilia'' (sunken disk lichen) 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.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Most of the species of this genus grow on calcareous and acidic rocks and most of the taxa prefer temperate and arctic habitats. Some members of the genus ''Aspicilia'' are pioneer species on granite and other hard rock, after which members of other lichen species may grow on them, such as members of ''Acarospora''.ACAROPSPORA, Lichen Flora of the Greater Sonoran Desert Region.
