Lepiota Rubrotinctoides
''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 gen ...

Lepiota Clypeolaria
Lepiota clypeolaria, commonly known as the shield dapperling or the shaggy-stalked Lepiota, is a common, eat mushroom in the genus ''Lepiota''. It is widely distributed in northern temperate zones, where it grows in deciduous and coniferous forest. Fruit bodies have a brownish cap, a shaggy stipe with a collapsed, sheathing ring or ring zone, and spindle-shaped spores. Taxonomy The species was first described in 1789 as ''Agaricus clypeolarius'' by French mycologist Jean Baptiste Francois Bulliard. Paul Kummer transferred it to ''Lepiota'' in 1871. It is commonly known as the "shaggy-stalked Lepiota". Description The cap is egg-shaped when young, soon broadly bell-shaped and has pale straw- or orange-brown scales on a pale background. The central umbo is covered with a well-delimited uniform disk of the same colour as the scales. It grows to a diameter of . The gills are white, crowded, free from attachment to the stipe. The white stem has an indistinct ring, below whic ...

Agaric
An agaric () is a type of fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. In the UK, agarics are called "mushrooms" or "toadstools". In North America they are typically called "gilled mushrooms". "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically, agaric meant 'tree-fungus' (after Latin ''agaricum''); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name ''Agaricus'' for gilled mushrooms. Most species of agaricus belong to the order Agaricales in the subphylum Agaricomycotina. The exceptions, where agarics have evolved independently, feature largely in the orders Russulales, Boletales, Hymenochaetales, and several other groups of basidiomycetes. Old systems of classification placed all agarics in the Agaricales and some (mostly older) sources use ...

Limacella
''Limacella'' is a genus of mushroom-forming fungi in the family Amanitaceae in order Agaricales. Some of the species have been classified as members of genus ''Lepiota''. ''Limacella'' was described by mycologist Franklin Sumner Earle in 1909. In some older classification schemes, ''Limacella'' has alternatively been placed in family Pluteaceae. The species formerly classified in the genus ''Limacella'' are now placed in 4 genera; ''Catatrama'', ''Limacellopsis'', ''Limacella'', and ''Zhuliangomyces ''Zhuliangomyces'' is a genus of mushroom-forming fungi in the family Amanitaceae The Amanitaceae is a family of mushroom-forming fungi.

Cystoderma
''Cystoderma'' is a genus of fungi in the family Agaricaceae or Cystodermataceae. Its family position is in doubt and the family "Cystodermataceae" and tribe "Cystodermateae" have been proposed to include this group following recent molecular work. Previously ''Cystoderma'' comprised a wider range of species but in 2002 Harmaja separated some of them off into the new genus '' Cystodermella'' (for instance '' Cystoderma cinnabarinum'', ''C. elegans'' and '' C. granulosum''). The separation was made largely on the basis that the spores in the new genus were not at all amyloid. Those remaining in ''Cystoderma'' have weakly to strongly amyloid spores, tend to have a persistent ring and to have arthroconidia. DNA analysis supports the division into the two groups, but further investigation has shown that none of the morphological characteristics distinguish between them in a consistent clear-cut way. The name probably comes from the Greek ''kýstis'' meaning ''pouch'' and ''derma' ...

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ...

Pholiota
''Pholiota'' is a genus of small to medium-sized, fleshy mushrooms in the family Strophariaceae. They are saprobes that typically live on wood. The genus has a widespread distribution, especially in temperate regions, and contains about 150 species. ''Pholiota'' is derived from the Greek word ''pholis'', meaning "scale". Taxonomic details The genus ''Pholiota'' includes mushrooms, with scaly, glutinous to dry cap surfaces, and that frequently grow on wood or at the bases of trees or on decaying tree roots, and spores that are brown, light brown, or yellowish brown in deposit. These spores are smooth with a germ pore, although the germ pore can be quite narrow in species. Usually the species have pleurocystidia that include a type called chrysocystidia. There have been several varying concepts of the genus, ranging from a pre- molecular era very broad concept that nowadays would include the genera '' Phaeolepiota'', ''Phaeonematoloma'', ''Flammula'', ''Meottomyces'', some '' ...

Cortinarius
''Cortinarius'' is a globally distributed genus of mushrooms in the family Cortinariaceae. It is suspected to be the largest genus of agarics, containing over 2,000 widespread species. A common feature among all species in the genus ''Cortinarius'' is that young specimens have a cortina (veil) between the cap and the stem, hence the name, meaning ''curtained''. Most of the fibres of the cortina are ephemeral and will leave no trace once gone, except for limited remnants on the stem or cap edge in some species. All have a rusty brown spore print. The common names cortinar and webcap refer to members of the genus. Due to dangerous toxicity of several species (such as ''Cortinarius orellanus'') and the fact that it is difficult to distinguish between various species of the genus, non-expert consumption of mushrooms from the genus is discouraged. Distinguishing features The veil protects the gills in younger specimens and usually disappears leaving little to no trace of itself as the ...

Armillaria
''Armillaria'' is a genus of fungi that includes the '' A. mellea'' species known as honey fungi that live on trees and woody shrubs. It includes about 10 species formerly categorized summarily as ''A. mellea''. ''Armillarias'' are long-lived and form the largest living fungi in the world. The largest known organism (of the species ''Armillaria ostoyae'') covers more than in Oregon's Malheur National Forest and is estimated to be 2,500 years old. Some species of ''Armillaria'' display bioluminescence, resulting in foxfire. ''Armillaria'' can be a destructive forest pathogen. It causes "white rot" root disease (see Plant pathology section) of forests, which distinguishes it from ''Tricholoma'', a mycorrhizal (non-parasitic) genus. Because ''Armillaria'' is a facultative saprophyte, it also feeds on dead plant material, allowing it to kill its host, unlike parasites that must moderate their growth to avoid host death. Description The basidiocarp (reproductive struc ...

Mycologist
Mycology is the branch of biology concerned with the study of fungus, fungi, including their genetics, genetic and biochemistry, biochemical properties, their Taxonomy (biology), taxonomy and ethnomycology, their use to humans, including as a source for tinder, traditional medicine, Edible mushroom, food, and entheogens, as well as their dangers, such as poison, toxicity or fungal infection, infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz ...

Section (biology)
In biology a section ( la, sectio) is a taxonomic rank that is applied differently in botany and zoology. In botany Within flora (plants), 'section' refers to a ''botanical'' rank below the genus, but above the species: * Domain > Kingdom > Division > Class > Order > Family > Tribe > Genus > Subgenus > Section > Subsection > Species In zoology Within fauna (animals), 'section' refers to a ''zoological'' rank below the order, but above the family: * Domain > Kingdom > Phylum > Class > Order > Section > Family > Tribe > Genus > Species In bacteriology The International Code of Nomenclature for Bacteria The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P.

Poisonous Mushroom
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxic substances. Its symptoms can vary from slight gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus. Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a toxic mushroom as an edible species. The most common reason for this misidentification is a close resemblance in terms of color and general morphology of the toxic mushrooms species with edible species. To prevent mushroom poisoning, mushroom gatherers familiarize themselves with the mushrooms they intend to collect, as well as with any similar-looking toxic species. The safety of eating wild mushrooms may depend on methods of preparation for cooking. Signs and symptoms Poisonous mushrooms contain a variety of different toxins that can differ markedly in toxicity. Symptoms of mushroom poisoning may vary from gastric upset ...

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 ...
