Myriostoma Coliforme
''Myriostoma coliforme'', commonly known as the saltshaker earthstar or pepper pot, is a fungal species in the family (biology), family Geastraceae. Basidiocarps resemble Geastrales, earthstars, but the spore sac is supported by multiple columns (instead of a single column) and has multiple ostioles instead of a single, apical ostiole. It has also been called "salt-shaker earthstar". The fungus has a north temperate distribution, but was formerly thought to be more widespread due to confusion with related ''Myriostoma'' species. ''Myriostoma coliforme'' is an uncommon species and appears on the Regional Red List, Red Lists of 12 European countries. In 2004 it was one of 33 species proposed for protected species, protection under the Convention on the Conservation of European Wildlife and Natural Habitats, Bern Convention by the European Council for Conservation of Fungi. Taxonomy The species was first mentioned in the scientific literature by Samuel Doody in the second edition of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Dickson (botanist)
James (Jacobus) J. Dickson (1738–1822) was a Scottish nurseryman, plant collector, botanist and mycologist. Between 1785 and 1801 he published his ''Fasciculus plantarum cryptogamicarum Britanniae'', a four-volume work in which he published over 400 species of algae and fungi that occur in the British Isles He is also the editor of the exsiccata work ''Hortus siccus Britannicus, being a collection of dried British plants, named on the authority of the Linnean herbarium and other original collections'' (1793–1802). The plant genus ''Dicksonia'' is named after him. Life He was born at Kirke House, Traquair, Peeblesshire, of poor parents, and began life in the gardens of the Earl of Traquair. While still young he went to Jeffery's nursery-garden at Brompton, and in 1772 started in business for himself in Covent Garden. Dickson made several tours in the Scottish Highlands in search of plants between 1785 and 1791, that of 1789 being in company with Mungo Park (explorer), Mungo ...

Coloured Figures Of English Fungi Or Mushrooms - T
Coloureds () are multiracial people in South Africa, Namibia and, to a smaller extent, Zimbabwe and Zambia. Their ancestry descends from the interracial mixing that occurred between Europeans, Africans and Asians. Interracial mixing in South Africa began in the 17th century in the Dutch Cape Colony where the Dutch men mixed with Khoi Khoi women, Bantu women and Asian female slaves, producing mixed race children. Eventually, interracial mixing occurred throughout South Africa and the rest of Southern Africa with various other European nationals (such as the Portuguese, British, Germans, Irish etc.) who mixed with other African tribes which contributed to the growing number of mixed-race people, who would later be officially classified as Coloured by the apartheid government. ''Coloured'' was a legally defined racial classification during apartheid referring to anyone not white or of the black Bantu tribes, which effectively largely meant people of colour. The majority o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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).

Mycelium
Mycelium (: mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Its normal form is that of branched, slender, entangled, anastomosing, hyaline threads. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form 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 biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall, or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that has fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O-horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is m ...

Sporocarp (fungus)
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production. The sporocarp of a basidiomycete is known as a ''basidiocarp'' or ''basidiome'', while the fruitbody of an ascomycete is known as an '' ascocarp''. Many shapes and morphologies are found in both basidiocarps and ascocarps; these features play an important role in the identification and taxonomy of fungi. Fruitbodies are termed ''epigeous'' if they grow on the ground, while those that grow underground are '' hypogeous''. Epigeous sporocarps that are visible to the naked eye, especially fruitbodies of a more or less agaricoid morphology, are often called mushrooms. Epigeous sporocarps have mycelia that extend underground far ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myriostoma Coliforme 46755
''Myriostoma'' is a fungal genus in the family Geastraceae. Basidiocarps resemble earthstars, but the spore sac is supported by multiple columns (instead of a single column) and has multiple ostioles instead of a single, apical ostiole. Until 2017, the genus was thought to be monotypic with a single, widespread species, ''Myriostoma coliforme''. Recent research has, however, shown that at least six species occur worldwide. Taxonomy and phylogeny Nicaise Auguste Desvaux first defined and published the genus ''Myriostoma'' in 1809, with the single species ''Myriostoma anglicum'' (an illegitimate renaming of James Dickson's original ''Lycoperdon coliforme''). In 1821 Samuel Frederick Gray described the superfluous genus ''Polystoma'' for it. ''Myriostoma'' was classified in the family Geastraceae until 1973, when British mycologist Donald Dring placed it in the Astraeaceae based on the presence of trabeculae (stout columns that extend from the peridium to the central core of ...

Colander
A colander (or cullender) is a kitchen utensil perforated with holes used to strain foods such as pasta or to rinse vegetables. The perforations of the colander allow liquid to drain through while retaining the solids inside. It is sometimes called a pasta strainer. A sieve, with much finer mesh, is also used for straining. Description and history Traditionally, colanders are made of a light metal, such as aluminium or thinly rolled stainless steel Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Stainless steel's resistance to corrosion comes from its chromi .... Colanders are also made of plastic, silicone, ceramic, and enamelware. The word ''colander'' comes from the Latin , meaning sieve. Types * Bowl- or cone-shaped – the usual colander * Mated colander pot – a colander inside a cooking pot, allowing the food to drain as it is l ...

Geastrum
''Geastrum'' (orthographical variant ''Geaster'') is a genus of puffball-like mushrooms in the family Geastraceae. Many species are commonly known as earthstars. The name, which comes from ''geo'' meaning ''earth'' and meaning ''star'', refers to the behavior of the outer peridium. At maturity, the outer layer of the fruiting body splits into segments which turn outward creating a star-like pattern on the ground. The inner peridium is called a spore sac. In some species, the outer peridium splits from a middle layer, causing the spore sac to arch off the ground. If the outer peridium opens when wet and closes when dry, it is described as hygroscopic. In some species, the inner peridium is borne on a stalk or pedicel. The columella is a column-like clump of sterile tissue found inside the inner peridium. The network of fertile tissue inside the inner peridium, the capillitium, arises from the columella. This is where basidia and basidiospores are produced. The mouth in most sp ...

Illegitimate Name
''Nomen illegitimum'' (Latin for illegitimate name) is a technical term used mainly in botany. It is usually abbreviated as ''nom. illeg.'' Although the International Code of Nomenclature for algae, fungi, and plants uses Latin terms as qualifiers for taxon names (e.g. ''nomen conservandum'' for "conserved name", and ''nomen superfluum'' for "superfluous name"), the definition of each term is in English rather than Latin. The Latin abbreviations are widely used by botanists and mycologists. Definition A ''nomen illegitimum'' is a validly published name, but one that contravenes some of the articles laid down by the International Botanical Congress.Melbourne Code (2012) The name could be illegitimate because: * (article 52) it was superfluous at its time of publication, i.e., the taxon (as represented by the |
