Hirticlavula
''Hirticlavula'' is a fungal genus in the family Clavariaceae. It contains a single described species, ''Hirticlavula elegans''. Formally described in 2014, the fungus has been collected from Norway and Denmark. ''H. elegans'' produces white fruit bodies up to in height. Each fruit body contains a fertile head atop a hairy stem. The fruit bodies grow directly from dead bark or wood, where they feed as saprotrophs. Both morphological and ecological details are distinctive when compared to other clavarioid fungi. Taxonomy ''Hirticlavula elegans'' was described based on collections dating back to 1995. It was provisionally reported in 2009 in the proceedings of a 2008 conference, before being formally described in 2009 by Jens H. Petersen and Thomas Læssøe in an article in '' Karstenia'', coauthored with Marie L. Davey.Petersen, Davey, and Læssøe, p. 1.

Clavariaceae
The Clavariaceae are a family of fungi in the order Agaricales. Originally the family contained most of the clavarioid fungi (club and coral fungi), but in its current sense is more restricted, albeit with a greater diversity of basidiocarp (fruit body) forms. Basidiocarps are variously clavarioid or agaricoid (mushroom-shaped), less commonly corticioid (effused, crust-like) or hydnoid (with pendant spines). Taxonomy History Clavariaceae was originally circumscribed (as "Clavariae") by French botanist and mycologist François Fulgis Chevallier in 1826. It was one of five families (along with the Agaricaceae, Hydnaceae, Polyporaceae, and Thelephoraceae) that Elias Fries used to divide the Agaricales and Aphyllophorales in his influential work '' Systema Mycologicum''. The family served as a convenient placement for all genera containing species with superficially similar club or coral-like fruitbodies. It was first M.A. Donk and later E.J.H. Corner who realized that, in this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

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 ellipsoi ... [...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.

Methyl Blue
Methyl blue is a chemical compound with the molecular formula C37H27N3Na2O9S3. It is used as a stain in histology, and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's connective tissue stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells. Fungal cell walls are also stained by methyl blue. Methyl blue is also available in mixture with water blue, under name Aniline Blue WS, Aniline blue, China blue, or Soluble blue; and in a solution of phenol, glycerol, and lactic acid under the name Lactophenol cotton blue (LPCB), which is used for microscopic visualization of fungi.

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 multic ...

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives. A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae. Inert substrates are used as growing support materials in the hydroponic cultivation of plants. In biology substrates are often activated by the nanoscopic process of substrate presentation. In agriculture and horticulture * Cellulose substrate * Expanded clay aggregate (LECA) * Rock wool * Potting soil * Soil In animal biotechnology Requirements for animal cell and tissue culture Requirements for animal cell and tissue culture are the same as described for plant cell, tissue and organ culture (In Vitro Culture Techniques: The Biotechnological Principles). Desirable requirements are (i) air conditioning of a room, (ii) hot room with temperature recorder, (iii) microsc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerotium
A sclerotium (; (), is a compact mass of hardened fungal mycelium containing food reserves. One role of sclerotia is to survive environmental extremes. In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return. Sclerotia initially were mistaken for individual organisms and described as separate species until Louis René Tulasne proved in 1853 that sclerotia are only a stage in the life cycle of some fungi. Further investigation showed that this stage appears in many fungi belonging to many diverse groups. Sclerotia are important in the understanding of the life cycle and reproduction of fungi, as a food source, as medicine (for example, ergotamine), and in agricultural blight management. Examples of fungi that form sclerotia are ergot ('' Claviceps purpurea''), ''Polyporus tuberaster'', '' Psilocybe mexicana'', '' Sclerotium delphinii'' and many species in Sclerotiniaceae. Although not fungal, the plasmodium of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cream (colour)
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 ...
