Leucopaxillus Giganteus
''Leucopaxillus giganteus'', commonly known as the giant leucopax (formerly as the giant clitocybe) or the giant funnel, is a saprobic species of fungus in the family Tricholomataceae. As its common names imply, the fruit body, or mushroom, can become quite large—the cap reaches diameters of up to . It has a white or pale cream cap, and is funnel-shaped when mature, with the gills running down the length of the stem. Considered by some to be a choice edible when young, this species has a cosmopolitan distribution, and is typically found growing in groups or rings in grassy pastures, roadside hedges, or woodland clearings. It has been shown to contain a bioactive compound with antibiotic properties. Taxonomy The species was first described as ''Agaricus giganteus'' by English naturalist James Sowerby in 1809, who illustrated it in his book ''Coloured Figures of English Fungi''. Other historical synonyms include ''Clitocybe gigantea'' ( Quélet, 1872), ''Paxillus giganteus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Sowerby
James Sowerby (21 March 1757 – 25 October 1822) was an English naturalist, illustrator and mineralogist. Contributions to published works, such as ''A Specimen of the Botany of New Holland'' or ''English Botany'', include his detailed and appealing plates. The use of vivid colour and accessible texts were intended to reach a widening audience in works of natural history. Biography James Sowerby was born in Lambeth, London, his parents were named John and Arabella. Having decided to become a painter of flowers his first venture was with William Curtis, whose ''Flora Londinensis'' he illustrated. Sowerby studied art at the Royal Academy and took an apprenticeship with Richard Wright. He married Anne Brettingham De Carle and they were to have three sons: James De Carle Sowerby (1787–1871), George Brettingham Sowerby I (1788–1854) and Charles Edward Sowerby (1795–1842), the Sowerby family of naturalists. His sons and theirs were to contribute and continue the enormous vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioactive Compound
A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential as the body can function without them or because their actions are obscured by nutrients fulfilling the function. Bioactive compounds lack sufficient evidence of effect or safety, and consequently they are usually unregulated and may be sold as dietary supplements. Origin and examples Bioactive compounds are commonly derived from plants, animal products, or can be synthetically produced. Examples of plant bioactive compounds are carotenoids, polyphenols, or phytosterols. Examples in animal products are fatty acids found in milk and fish. Other examples are flavonoids, caffeine, choline, coenzyme Q, creatine, dithiolthiones, polysaccharides, phytoestrogens, glucosinolates, and prebiotics. In the diet The ...

Ovoid
An oval () is a closed curve in a plane which resembles the outline of an egg. The term is not very specific, but in some areas (projective geometry, technical drawing, etc.) it is given a more precise definition, which may include either one or two axes of symmetry of an ellipse. In common English, the term is used in a broader sense: any shape which reminds one of an egg. The three-dimensional version of an oval is called an ovoid. Oval in geometry The term oval when used to describe curves in geometry is not well-defined, except in the context of projective geometry. Many distinct curves are commonly called ovals or are said to have an "oval shape". Generally, to be called an oval, a plane curve should ''resemble'' the outline of an egg or an ellipse. In particular, these are common traits of ovals: * they are differentiable (smooth-looking), simple (not self-intersecting), convex, closed, plane curves; * their shape does not depart much from that of an ellipse, and * an o ...

Light Microscope
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although many complex designs aim to improve resolution and sample contrast. The object is placed on a stage and may be directly viewed through one or two eyepieces on the microscope. In high-power microscopes, both eyepieces typically show the same image, but with a stereo microscope, slightly different images are used to create a 3-D effect. A camera is typically used to capture the image (micrograph). The sample can be lit in a variety of ways. Transparent objects can be lit from below and solid objects can be lit with light coming through ( bright field) or around (dark field) the objective lens. Polarised ...

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 ...

It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it ...

Trama (mycology)
In mycology, the term trama is used in two ways. In the broad sense, it is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue that is commonly referred to as the "flesh" of mushrooms and similar fungi.Largent D, Johnson D, Watling R. 1977. ''How to Identify Mushrooms to Genus III: Microscopic Features''. Arcata, CA: Mad River Press. . pp. 60–70. The second use is more specific, and refers to the "hymenophoral trama" that supports the hymenium. It is similarly interior, connective tissue, but it is more specifically the central layer of hyphae running from the underside of the mushroom cap to the lamella or gill, upon which the hymenium rests. Various types have been classified by their structure, including trametoid, cantharelloid, boletoid, and agaricoid, with agaricoid the ...

Mycelium
Mycelium (plural mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Fungal colonies composed of mycelium are found in and on soil and many other substrate (biology), substrates. A typical single spore germinates into a Monokaryon, monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form sporocarp (fungi), fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in ''Armillaria''. Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biopolymers, biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active transport. Mycelia are v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guide A field guide is a book designed to help the reader identify wildlife (flora or fauna) or other objects of natural occurrence (e.g. rocks and minerals). It is generally designed to be brought into the "field" or local area where such objects exi ...s and on identification websites. Ring descriptions The way in which the structure and appea ...

Buff (color)
Buff (latin ''bubalinus'') is a light brownish yellow, ochreous colour, typical of buff leather. Buff is a mixture of yellow ochre and white: two parts of white lead and one part of yellow ochre produces a good buff, or white lead may be tinted with French ochre alone. As an RYB quaternary colour, it is the colour produced by an equal mix of the tertiary colours citron and russet. Etymology The first recorded use of the word ''buff'' to describe a colour was in ''The London Gazette'' of 1686, describing a uniform to be "...a Red Coat with a Buff-colour'd lining". It referred to the colour of undyed buffalo leather, such as soldiers wore as some protection: an eyewitness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he would neither put on arms rmouror buff coat the day of the battle". Such buff leather was suitable for ''buffing'' or serving as a ''buffer'' between polished objects. It is not clear which bovine "''buffalo''" referred t ...

Coloured Figures Of English Fungi Or Mushrooms - T
Coloureds ( af, Kleurlinge or , ) refers to members of multiracial ethnic communities in Southern Africa who may have ancestry from more than one of the various populations inhabiting the region, including African, European, and Asian. South Africa's Coloured people are regarded as having some of the most diverse genetic background. Because of the vast combination of genetics, different families and individuals within a family may have a variety of different physical features. ''Coloured'' was a legally defined racial classification during apartheid referring to anyone not white or not a member of one the aboriginal groups of Africa on a cultural basis, which effectively largely meant those people of colour not speaking any indigenous languages. In the Western Cape, a distinctive Cape Coloured and affiliated Cape Malay culture developed. In other parts of Southern Africa, people classified as Coloured were usually the descendants of individuals from two distinct ethnicities ...
