Lepiota Ignivolvata
''Lepiota ignivolvata'', sometimes known commonly as the orange-girdled parasol, is a fairly rare member of the gilled mushroom genus ''Lepiota''. It is among the larger species in this group, growing in coniferous or deciduous woodland during autumn; it has a primarily European distribution. Being inedible, and perhaps poisonous, it should not be gathered for culinary use. Many of the species in this genus are deadly. Description The cap is between in diameter. It is convex, later flat, and with a raised central boss (umbo). The centre of the cap is reddish brown, or orange-brown, breaking into small scales, which are fewer, and lighter towards the margin. The best identification aid is the orange (somewhat indented) ring, which is low on the white, slightly bulbous to club-shaped stem, which often has an orange flush at its base. The gills are white to cream, giving a white spore print. They are free of the stem, and are fairly crowded together. The flesh is white throughout ...

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "puffball", "stinkhorn", and " morel", and gilled mushrooms themselves are often called "agarics" in refere ...

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] |

Beech
Beech (''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, ''Engleriana'' and ''Fagus''. The ''Engleriana'' subgenus is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known ''Fagus'' subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech (''Fagus sylvatica'') is the most commonly cultivated. Beeches are monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small burrs that drop from the tree in autumn. They are small, roughly triangular, and edible, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Société Mycologique De France
The Société mycologique de France (Mycological Society of France), often known by the abbreviation SMF, is an association linking French and French-speaking mycologists. History The society was founded in 1884 in Épinal in the Vosges by three doctors, Lucien Quélet (1832-1889), Antoine Mougeot (1815-1889) and René Joseph Justin Ferry (1845-1924), joined by two pharmacists, Émile Boudier (1828-1920) and Narcisse Théophile Patouillard (1854-1926). The object of the society was to "Establish relationships between mycologists scattered in various parts of French territory, centralize their research and thereby achieve the foundation of a complete fungal flora of France". It was the first mycological society in the world. One year after its creation it already had 128 members and three years later it had 250. Most founder members were pharmacists, doctors or teachers and then it opened to amateurs. The society's headquarters are located at 20 rue Rottembourg in the 12th ...

Marcel Josserand
Marcel Josserand (5 October 1900 – 28 March 1992) was a French mycologist. Biography Marcel Josserand was born in Lyon in 1900 and died also in Lyon in 1992. He devoted the greater part of his life to the study of fungi, especially those normally described as mushrooms (that is, agarics). In 1923, he co-created the Mycological section of the Linnaean Society of Lyon, of which he was later president at various times. From 1938 he collaborated with the famous mycologist Robert Kühner in Lyon. His best-known book was "La description des Champignons supérieurs (Basiodiomycètes charnus) - technique descriptive, vocabulaire raisonné du descripteur" . Relevant species Two examples of fungi for which he was the name author are ''Macrocystidia cucumis'' (Pers.) Joss. in 1934 and ''Lepiota ignivolvata'' Bousset & Joss. ex Joss. in 1990 following an earlier description in 1948. Also the following mushrooms were all named after him. *''Cortinarius josserandii'' Bidaud (1994) * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusiform
Fusiform means having a spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel. Examples * Fusiform, a body shape common to many aquatic animals, characterized by being tapered at both the head and the tail * Fusiform, a classification of aneurysm * Fusiform bacteria (spindled rods, that is, fusiform bacilli), such as the Fusobacteriota * Fusiform cell (biology) * Fusiform face area, a part of the human visual system which seems to specialize in facial recognition * Fusiform gyrus, part of the temporal lobe of the brain * Fusiform muscle, where the fibres run parallel along the length of the muscle * Fusiform neuron, a spindle-shaped neuron A neuron, neurone, or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses.

Lepiota
''Lepiota'' is a genus of gilled mushrooms in the family Agaricaceae. All ''Lepiota'' species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps (fruit bodies) are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of ''Lepiota'' are currently recognized worldwide. Many species are poisonous, some lethally so. Taxonomy History ''Agaricus'' section ''Lepiota'' was originally published in 1797 by South African-born mycologist Christian Hendrik Persoon. It was subsequently raised to the rank of genus by Samuel Frederick Gray. As originally conceived, the genus was a mix of agarics with rings on their stems, including species now placed in ''Armillaria'', ''Cortinarius'', and ''Pholiota''. In 1822, however, the influential Swedish mycologist Elias Magnus Fries restricted ''Lepiota'' to white-spored, ringed agarics. Based on macro- and micromorphology, later authors gradually refined the gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
