Fauriea Chujaensis
''Fauriea'' is a genus of lichen-forming fungi in the family Teloschistaceae. The genus, which contains seven species, is a member of the subfamily Caloplacoideae. Characteristics of the genus ''Fauriea'' include its crustose lichen, crustose, continuous grey to whitish-grey thallus and (fruiting structures) with a brown or dark brown . The thallus has a sleek, continuous structure that is not , with greyish colours. The apothecia, which initially appear submerged within the thallus, later partially emerge or can be seen in structures called thalline warts. Taxonomy ''Fauriea'' was circumscription (taxonomy), circumscribed in 2016 by lichenologists Sergey Kondratyuk, Laszlo Lőkös, and Jae-Seoun Hur, with ''Fauriea chujaensis'' assigned as the type species. The genus was named in honour of French botanist Urbain Jean Faurie (1847–1915), who made significant contributions to the scientific collection, collections of lichens, mosses and vascular plants in the Eastern Asian re ...

Scientific Collection
A scientific collection is a collection of items that are preserved, catalogued, and managed for the purpose of scientific study. Scientific collections dealing specifically with organisms plants, fungi, animals, insects and their remains, may also be called natural history collections or biological collections. The latter may contain either living stocks or preserved repositories of biodiversity specimens and materials. Scientific collections hold a tangible portion of the cumulative evidence base in such fields as biology (especially taxonomy and evolutionary biology), geology, and archaeology. They may be stored and managed by governments, educational institutions (e.g. colleges and universities), private organizations (including museums), or individuals. Prominent uses of scientific collections include the systematic description and identification of biological species, the study and prediction of long-term historical trends (including impacts of climate change), the dating ...

Spot Test (lichen)
A spot test in lichenology is a spot analysis used to help identify lichens. It is performed by placing a drop of a chemical on different parts of the lichen and noting the colour change (or lack thereof) associated with application of the chemical. The tests are routinely encountered in dichotomous keys for lichen species, and they take advantage of the wide array of lichen products produced by lichens and their uniqueness among taxa. As such, spot tests reveal the presence or absence of chemicals in various parts of a lichen. They were first proposed by the botanist William Nylander in 1866. Three common spot tests use either 10% aqueous KOH solution (K test), saturated aqueous solution of bleaching powder or calcium hypochlorite (C test), or 5% alcoholic ''p''-phenylenediamine solution (P test). The colour changes occur due to presence of particular secondary metabolites in the lichen. There are several other less frequently used spot tests of more limited use that are employed ...

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular sep ...

Ellipsoid
An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular axes of symmetry which intersect at a center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal axes'', or simply axes of the ellipsoid. If the three axes have different lengths, the figure is a triaxial ellipsoid (r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascus
An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. ''Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. ''Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some ''Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bourrelet ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Lecanora
''Lecanora'' is a genus of lichen commonly called rim lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens in the genus ''Squamarina'' are also called rim lichens. Members of the genus have roughly circular fruiting discs (apothecia) with rims that have photosynthetic tissue similar to that of the nonfruiting part of the lichen body (thallus). Other lichens with apothecia having margins made of thallus-like tissue are called lecanorine. ''Lecanora'' has a crustose thallus, trebouxoid photobiont, colourless ascospores and crystals in the amphitecium. It is in the family Lecanoraceae in the suborder Lecanorineae. Species : *'' Lecanora campestris'' (Schaer.) Hue 1888 *''Lecanora conizaeoides'' Nyl. ex Cromb. 1885 *'' Lecanora gangaleoides'', Nyl. 1872 *'' Lecanora grantii'', H.

Caloplaca Lecanorocarpa
''Caloplaca lecanorocarpa'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Found in Brazil, it was formally described as a new species in 2016 by the lichenologists André Aptroot and Marcela Cáceres. It is named for its overall appearance to lichens in the ''Lecanora subfusca'' species complex. Description The thallus of ''Caloplaca lecanorocarpa'' is crustose (crust-like) and (having a protective outer layer), slightly shiny, and grey in colour. The (small patches on the thallus) range from round to angular, measuring approximately 0.2–1.0 mm in diameter, and rest on a black (a layer below the thallus). The thallus is about 100–220 μm thick, with a loosely arranged medulla (inner layer) and a cortex containing atranorin crystals, which are about 10–18 μm thick. The cells within the lichen are (round, green algae) and measure roughly 6–11 μm in diameter. The apothecia (fruiting bodies) ...

Caloplaca Lecapustulata
''Caloplaca lecapustulata'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. Found in Brazil, it was described as a new species in 2016. Taxonomy ''Caloplaca lecapustulata'' was formally described as a new species by the lichenologists André Aptroot and Marcela Cáceres. The type specimen was collected by the authors in Brazil, within the state of Ceará at Açude Cedro, specifically along the trail of Pedra da Galinha. This collection took place on a gneiss inselberg (an isolated hill rising abruptly from a plain) within the Caatinga biome, at an elevation of about above sea level. Description ''Caloplaca lecapustulata'' is characterised by a crustose (crust-like), , and slightly shiny thallus (the main body of the lichen) that is grey in colour.

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 ...
