Ameliella Grisea
''Ameliella'' is a genus of lichenized fungi in the family Lecanoraceae. Described in 2008, the genus contains two species, ''A. andreaeicola'' and ''A. grisea'', that were collected from high elevations in the Scottish Highlands. The two species have also been found in single instances in British Columbia and Northern Norway. The generic name is derived from the Greek , meaning "neglected" or "overlooked"; it was originally intended to be ''Amelia'', which is also the first name of the daughter of one of the authors, but this name had previously been used for another genus and was therefore ineligible for use according to the rules of mycological nomenclature. ''Ameliella'' appears to have some similarity with the lichen genus ''Miriquidica''. The genus name of ''Ameliella'' is in honour of Amelia Rogocka Fryday (b.1993). The genus was circumscribed by Alan M. Fryday and Brian John Coppins in Lichenologist Vol.40 on page 388 in 2008. Description In the genu ...

Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichen Genera
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 .

They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Species Diversity
Species diversity is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant). Meanings of species diversity may include species richness, taxonomic or phylogenetic diversity, and/or species evenness. Species richness is a simple count of species. Taxonomic or phylogenetic diversity is the genetic relationship between different groups of species. Species evenness quantifies how equal the abundances of the species are.Hill, M. O.

Troms
Troms (; se, Romsa; fkv, Tromssa; fi, Tromssa) is a former county in northern Norway. On 1 January 2020 it was merged with the neighboring Finnmark county to create the new Troms og Finnmark county. This merger is expected to be reversed by the government resulting from the 2021 Norwegian parliamentary election. It bordered Finnmark county to the northeast and Nordland county in the southwest. Norrbotten Län in Sweden is located to the south and further southeast is a shorter border with Lapland Province in Finland. To the west is the Norwegian Sea (Atlantic Ocean). The entire county, which was established in 1866, was located north of the Arctic Circle. The Troms County Municipality was the governing body for the county, elected by the people of Troms, while the Troms county governor was a representative of the King and Government of Norway. The county had a population of 161,771 in 2014. General information Name Until 1919, the county was formerly known as ''Tromsø a ...

Epispore
The following is a glossary of terms used in the description of lichens, composite organisms that arise from algae or cyanobacteria living among filaments of multiple fungus species in a mutualistic relationship. Until the end of the 18th century, only a couple of lichen-specific terms had been proposed. Johann Dillenius introduced ' in 1742 to describe the cup-shaped structures associated with genus ''Cladonia'', while in 1794 Michel Adanson used ' for the furrowed fruitbodies of the genus '' Graphis''. Erik Acharius, the "father of lichenology", conceived many new terms to describe lichen structures in several of his seminal publications in the early 1800s. Examples include , , , , , , and . In 1825, Friedrich Wallroth published the first of his multi-volume work ''Naturgeschichte der Flechten'' ("Natural History of Lichens"), in which he proposed an alternative terminology based largely on roots from the Greek language. His work, presented as an alternative to that of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from el, ὑάλινος, translit=hyálinos, lit=transparent, and el, ὕαλος, translit=hýalos, lit=crystal, glass, label=none. Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology, ''hyaline'' denotes a colorless, transparent substance, such as unpigmented fins of fishes or clear insect wings. Resh, Vincent H. and R. T.
