Hygrophoropsis Macrospora
''Hygrophoropsis macrospora'' is a species of fungus in the family Hygrophoropsidaceae. It is found in Europe and North America. Taxonomy Formally described by Derek Reid in 1972 as a variety of '' Hygrophoropsis aurantiaca'', it was raised to distinct species status by Thomas Kuyper in 1996. ''Hygrophoropsis pallida'' (Peck) Kreisel is a synonym that was never formally published. It is based on Charles Horton Peck's taxon ''Cantharellus aurantiatus'' var. ''pallidus'', which he published in 1896. Description Fruit bodies of ''Hygrophoropsis macrospora'' have a cream- to tan-coloured cap with a felt-like surface texture. The gills are forked and yellowish, with a decurrent attachment to the stipe. ''Hygrophoropsis macrospora'' differs from ''H. aurantiaca'' mainly by its larger spore size, measuring 8.0–11.0 (sometimes up to 13.0) by 3.0–4.5 (5.0) μm The micrometre ( international spelling as used by the International Bureau of Weights and Measures; ...

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tan (color)
Tan is a pale tone of brown. The name is derived from tannum (oak bark) used in the tanning of leather. The first recorded use of ''tan'' as a color name in English was in the year 1590. Colors which are similar or may be considered synonymous to tan include: tawny, tenné, and fulvous. __TOC__ Variations of tan Sandy tan Displayed at right is the color ''Sandy tan''. This color was formulated by Crayola in 2000 as a Crayola marker color. Tan (Crayola) Displayed at right is the orangish tone of tan called ''tan'' since 1958 in Crayola crayons and 1990 in Crayola markers. Windsor tan Displayed at right is the color ''Windsor tan''. The first recorded use of ''Windsor tan'' as a color name in English was in 1925. Tuscan tan Displayed at right is the color ''Tuscan tan''. The first recorded use of ''Tuscan tan'' as a color name in English was in 1926. The normalized color coordinates for Tuscan tan are identical to café au lait and French beige, which ...

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] |
Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...

Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or universal ve ...

Decurrent
''Decurrent'' (sometimes decurring) is a term used in botany and mycology to describe plant or fungal parts that extend downward. In botany, the term is most often applied to leaf blades that partly wrap or have wings around the stem or petiole and extend down along the stem. A "decurrent branching habit" is a plant form common for shrubs and most angiosperm trees, contrasted with the excurrent or "cone-shaped crown" common among many gymnosperms. The decurrent habit is characterized by having weak apical dominance that eventually produces a rounded or spreading tree crown. Examples of trees with decurrent habit are most hardwood trees: oak, hickory, maple, etc.Claud L. Brown, Robert G. McAlpine, Paul P. Kormanik, "Apical Dominance and Form in Woody Plants: A Reappraisal", ''American Journal of Botany'', Vol. 54, No. 2 (February 1967), pp. 153–162, In mycology, the term is most often applied to the hymenophore of a basidiocarp (such as the lamellae or "gills" of a mushroo ...

Lamella (mycology)
In mycology, a lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, ''Lactarius'' species typically seep latex from their gills. It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills is that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cream (color)
Cream is the colour of the cream produced by cattle grazing on natural pasture with plants rich in yellow carotenoid pigments, some of which are incorporated into the fresh milk (specifically, the butterfat). This gives a yellow tone to otherwise-white milk at higher fat concentrations (so the colour of dairy cream could be considered partway between the colours of natural cow’s milk and butter). Cream is the pastel colour of yellow, much as pink is to red. By mixing yellow and white, cream can be produced. The first recorded use of ''cream'' as a colour name in English was in 1590. In nature ;Birds * The cream-coloured courser * The cream-coloured woodpecker ;Mammals * The cream-coloured giant squirrel In human culture Art * Cream is used as a skin tone in some forms of art, mostly anime. It is also used to describe the general skin tone of East and South East Asia. Clothing * Men's white tuxedo jackets are usually a shade of cream or ivory to better stand out against ...

Hygrophoropsidaceae
The Hygrophoropsidaceae are a family of mushrooms that are gilled in appearance but lie within the Boletales. The family contains 18 species within two genera: ''Leucogyrophana'' and ''Hygrophoropsis'', with the best-known member being the "false chanterelle", ''Hygrophoropsis aurantiaca''. Hygrophoropsidaceae was circumscribed by French mycologist Robert Kühner in 1980, with ''Hygrophoropsis'' as the type genus. Unlike most members of the Boletales, Hygrophoropsidaceae species are saprophytic wood-rotting fungi that cause brown rot in their hosts. The genera ''Austropaxillus'' and '' Tapinella'', once placed in this family, are now classified in the Serpulaceae and Tapinellaceae The Tapinellaceae are a family of fungi in the order Boletales The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and unt ..., respectively. References Basidiomycota ... [...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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
