Ramaria Magnipes
''Ramaria magnipes'' is a coral fungus in the family Gomphaceae. It is found in western North America, where it fruits on the ground in mixed forests. Taxonomy The species was described as new to science in 1974 by Currie Marr and Daniel E. Stuntz in their monograph of ''Ramaria'' species of western Washington. The type collection was made near Merritt, Chelan County, Washington in 1967. The variety ''albidior'' was described by Ronald H. Petersen in 1988. Description The coral-shaped fruit bodies are relatively large, with dimensions of by . The large stipe, which roots into the soil, is tapered to conical, measuring long by thick; it stains brown in age. The color of fresh fruit bodies ranges from light yellow to brownish pale orange (with white flesh), while dried specimens tend to be paler, from pale yellow to grayish orange (with pale yellow flesh); the flesh has a slow and mild amyloid reaction. The branches are compact (giving the fruit body a cauliflower-lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Currie Marr
Currie ( gd, Currach, IPA: kŹ°uĖįµ²Éx is a village and suburb on the outskirts of Edinburgh, Scotland, situated south west of the city centre. Formerly within the County of Midlothian, it now falls within the jurisdiction of the City of Edinburgh Council. It is situated between Juniper Green to the northeast and Balerno to the southwest. It gives its name to a civil parish. In 2001, the population of Currie was 8,550 and it contained 3,454 houses. Etymology The name is recorded from 1210 onwards under various spellings such as ''Curey'', ''Cory'', ''Curri'' with ''Currie'' in 1402. There is no accepted derivation of the name Currie but it is possibly from the Scottish Gaelic word ''curagh/curragh'', a wet or boggy plain, or from the Brythonic word ''curi'', a dell or dirt hole. The neighbouring suburb of Balerno derives its name from Scottish Gaelic, whilst the nearby Pentland Hills derive their name from Brythonic, so either is possible. History The earli ...

Amyloid
Amyloids are aggregates of proteins characterised by a Fibril, fibrillar morphology of 7ā13 Nanometer, nm in diameter, a beta sheet (Ī²-sheet) Secondary structure of proteins, secondary structure (known as cross-Ī²) and ability to be Staining, stained by particular dyes, such as Congo red. In the human body, amyloids have been linked to the development of various diseases. Pathogenic amyloids form when previously healthy proteins lose their normal Protein structure, structure and physiology, physiological functions (Protein misfolding, misfolding) and form fibrous deposits in amyloid plaques around cells which can disrupt the healthy function of tissues and organs. Such amyloids have been associated with (but not necessarily as the cause of) more than 50 human diseases, known as amyloidosis, and may play a role in some neurodegenerative diseases. Some of these diseases are mainly sporadic and only a few cases are Genetic disorder, familial. Others are only Genetic disorder, fam ...

Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across eastāwest. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils ...

Idaho
Idaho ( ) is a state in the Pacific Northwest region of the Western United States. To the north, it shares a small portion of the CanadaāUnited States border with the province of British Columbia. It borders the states of Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. The state's capital and largest city is Boise. With an area of , Idaho is the 14th largest state by land area, but with a population of approximately 1.8 million, it ranks as the 13th least populous and the 7th least densely populated of the 50 U.S. states. For thousands of years, and prior to European colonization, Idaho has been inhabited by native peoples. In the early 19th century, Idaho was considered part of the Oregon Country, an area of dispute between the U.S. and the British Empire. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead ...

Macon County, North Carolina
Macon County is a county located in the U.S. state of North Carolina. As of the 2020 census, the population was 37,014. Its county seat is Franklin. The Nantahala River runs through Macon County, flowing into the Little Tennessee River in Swain County. The Nantahala is one of the most popular whitewater rafting destinations in the nation. History The river valleys were long occupied by indigenous peoples, some of whom built earthwork mounds about 1000 CE. Some are still visible in this region. It was part of the homeland of the historic Cherokee people, who had towns throughout the river valleys. The county was formed in 1828 from the western part of Haywood County. It was named for Nathaniel Macon, who represented North Carolina in the United States House of Representatives from 1791 to 1815 (serving as Speaker of the House from 1801 to 1807), and in the United States Senate from 1815 to 1828. In 1839 the western part of Macon County became Cherokee County. In 1851 par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramaria Highlandensis
The genus ''Ramaria'' comprises approximately 200 species of coral fungi. Several, such as ''Ramaria flava'', are edible and picked in Europe, though they are easily confused with several mildly poisonous species capable of causing nausea, vomiting and diarrhea; these include '' R. formosa'' and '' R. pallida''. Three ''Ramaria'' species have been demonstrated to contain a very unusual organoarsenic compound homoarsenocholine. Etymology The genus name is derived from Latin ''rÄmus'' meaning ''branch''. Description Basidiocarps may range in color from bright yellow, red, or orange, to purple, white, and shades of tan. Color changes after bruising occur in some species. The spores of ''Ramaria'' species are yellow-brown to rusty-brown in mass deposit and range from smooth to warted to echinulate or striate; spore size may range considerably, and ornamentation, when present, is cyanophilous. Classification Hjomskƶld was the first to introduce the name ''Ramaria'' in 1790. P ... [...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;ā 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] |
Sterigmata
In biology, a sterigma (pl. sterigmata) is a small supporting structure. It commonly refers to an extension of the basidium (the spore-bearing cells) consisting of a basal filamentous part and a slender projection which carries a spore at the tip. The sterigmata are formed on the basidium as it develops and undergoes meiosis, to result in the production of (typically) four nuclei. The nuclei gradually migrate to the tips of the basidium, and one nucleus will migrate into each spore that develops at the tip of each sterigma. In less common usage, a sterigma is a structure within the posterior end of the genitalia of female Lepidoptera. It also refers to the stem-like structure, also called a "woody peg" at the base of the leaves of some, but not all conifers, specifically ''Picea'' and ''Tsuga ''Tsuga'' (, from Japanese (), the name of ''Tsuga sieboldii'') is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family.

Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...

Stain
A stain is a discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. They are caused by the chemical or physical interaction of two dissimilar materials. Accidental staining may make materials appear used, degraded or permanently unclean. Intentional staining is used in biochemical research and for artistic effect, such as wood staining, rust staining and stained glass. Types There can be intentional stains (such as wood stains or paint), indicative stains (such as food coloring or adding a substance to make bacteria visible under a microscope), natural stains (such as rust on iron or a patina on bronze), and accidental stains such as ketchup and synthetic oil on clothing. Different types of material can be stained by different substances, and stain resistance is an important characteristic in modern textile engineering. Formation The primary method of stain formation is surface stains, where the staining substance is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
