Amanita Abrupta
''Amanita abrupta'', commonly known as the American abrupt-bulbed amanita or the American abrupt-bulbed lepidella, is a species of fungus in the family Amanitaceae. Named for the characteristic shape of its fruit bodies, this white ''Amanita'' has a slender stem, a cap covered with conical white warts, and an "abruptly enlarged" swollen base. This terrestrial species grows in mixed woods in eastern North America and eastern Asia, where it is thought to exist in a mycorrhizal relationship with a variety of both coniferous and deciduous tree species. Taxonomy ''Amanita abrupta'' was first described by American mycologist Charles Horton Peck in 1897, based on a specimen he found in Auburn, Alabama. Because the remains of the volva are not present on the bulb in dried, mature, specimens, Peck thought that the species should be grouped with '' Amanita rubescens'' and '' A. spissa''. Synonyms include binomials resulting from generic transfers by Jean-Edouard Gilbert to ''L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Horton Peck
Charles Horton Peck (March 30, 1833 – July 11, 1917) was an American mycologist of the 19th and early 20th centuries. He was the New York State Botanist from 1867 to 1915, a period in which he described over 2,700 species of North American fungi. Biography Charles Horton Peck was born on March 30, 1833, in the northeastern part of the town Sand Lake, New York, now called Averill Park. After suffering a light stroke early in November 1912 and then a severe stroke in 1913, he died at his house in Menands, New York, on July 11, 1917. In 1794, Eleazer Peck (his great grandfather) moved from Farmington, Conn. to Sand Lake, NY attracted by oak timber that was manufactured for the Albany market. Later on, Pamelia Horton Peck married Joel B., both from English descent, and became Charles Peck parents (Burnham 1919; Atkinson 1918). Even though his family was rich and locally prominent, his education was provincial (Haines 1986). During his childhood, he used to enjoy fishing and h ...

Amanita
The genus ''Amanita'' contains about 600 species of agarics, including some of the most toxic known mushrooms found worldwide, as well as some well-regarded edible species. This genus is responsible for approximately 95% of the fatalities resulting from mushroom poisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is α-Amanitin. The genus also contains many edible mushrooms, but mycologists discourage mushroom hunters, other than experts, from selecting any of these for human consumption. Nonetheless, in some cultures, the larger local edible species of ''Amanita'' are mainstays of the markets in the local growing season. Samples of this are ''Amanita zambiana'' and other fleshy species in central Africa, ''Amanita basii, A. basii'' and similar species in Mexico, ''Amanita caesarea, A. caesarea'' and the "Blusher" ''Amanita rubescens'' in Europe, and ''Amanita chepangiana, A. chepangiana'' in South-East Asia.

Amanita Onusta
''Amanita onusta'', commonly known as the loaded Lepidella, the gunpowder Lepidella or the gunpowder amanita, is a species of fungus in the mushroom family Amanitaceae. It is characterized by its small to medium-sized fruit bodies that have white to pale gray caps crowded with roughly conical, pyramidal, or irregular gray warts. The stipe is whitish-gray with woolly or wart-like veil remnants, and at the base is a spindle- or turnip-shaped base that is rooted somewhat deeply in the soil. The species is distributed in eastern North America, from Nova Scotia to Mexico, and may be found growing on the ground in deciduous forests, particularly those with oak, hickory and chestnut. Fruit bodies smell somewhat like bleaching powder, and their edibility is unknown, but possibly toxic. Taxonomy ''Amanita onusta'' was first described in 1874 by American mycologist Elliot Calvin Howe as ''Agaricus onustus''. Later, in 1891, Pier Andrea Saccardo transferred the species to the genus ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amanita Daucipes
''Amanita daucipes'' is a species of fungus in the family Amanitaceae of the mushroom order Agaricales. Found exclusively in North America, the mushroom may be recognized in the field by the medium to large white pileus (mycology), caps with pale orange tints, and the dense covering of pale orange or reddish-brown powdery conical warts on the cap surface. The mushroom also has a characteristic large bulb at the base of its stipe (mycology), stem with a blunt short rooting base, whose shape is suggestive of the common names carrot-footed lepidella, carrot-foot amanita, or turnip-foot amanita. The mushroom has a strong odor that has been described variously as "sweet and nauseous", or compared to an old ham bone, or soap. Edible mushroom, Edibility is unknown for the species, but consumption is generally not recommended due its position in the ''Amanita'' subgroup ''Lepidella'', which contains some poisonous members.

Amanita Cokeri
''Amanita cokeri'', commonly known as Coker's amanita and solitary lepidella, is a mushroom in the family Amanitaceae. The mushroom is poisonous. First described as ''Lepidella cokeri'' in 1928, it was transferred to the genus ''Amanita'' in 1940. Taxonomy ''Amanita cokeri'' was first described as ''Lepidella cokeri'' by mycologists E.-J.Gilbert and Robert Kühner in 1928. It was in 1940 when the species was transferred from genus ''Lepidella'' to ''Amanita'' by Gilbert. Presently, ''A. cokeri'' is placed under genus ''Amanita'' and section ''Roanokenses''. The epithet ''cokeri'' is in honour of American mycologist and botanist William Chambers Coker. Description Its cap is white in colour, and across. It is oval to convex in shape. The surface is dry but sticky when wet. The cap surface is characterized by large pointed warts, white to brown in colour. Gills are closely spaced and free from the stem. They are cream at first, but can turn white as the mushroom matures. Sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amanita Chlorinosma
''Amanita chlorinosma'', also known as the chlorine lepidella or chlorine Amanita, is a species of Amanita that can be found mainly in North Carolina (Piedmont and Coastal Plain mainly) but can range from Massachusetts and Illinois and south to Florida in pine and oak forest woodlands. Its life cycle is perennial. The strong chlorine or rotting meat odor coming from it makes this easily recognized. Toxicity The Amanita chlorinosma is strongly considered to be toxic due to its many poisonous characteristics, although little research has been done on this particular species. This mushroom's poisonous nature is indicated by its large size, powdered cap, enlarged stalk base, and strong chlorine or rotten meat odor. The stem is said to be the most poisonous component. It is expected that it would cause symptoms like other Amanita species if ingested: nausea, vomiting, disorientation, abdominal aches, etc. 30 minutes to several hours after consumption, symptoms start to appear.

Amanita Atkinsoniana
''Amanita atkinsoniana'', also known as the Atkinson's amanita, is a species of fungus in the family Amanitaceae. It is found in the northeastern, southeastern, and southern United States as well as southern Canada, where it grows solitarily or in small groups on the ground in mixed woods. The fruit body is white to brownish, with caps that measure up to in diameter, and stems up to long and thick. The surface of the cap is covered with reddish-brown to grayish-brown conical warts. The stem has a bulbous base covered with grayish-brown scales. The fruit bodies smell faintly like bleaching powder. Although not known to be poisonous, the mushroom is not recommended for consumption. Taxonomy The species was first described by American botanist William Chambers Coker in 1917, in his monograph of Amanitas of the eastern United States. Coker's description was based on several specimens he had collected from various locations in North Carolina in September and October 1914. The spe ...

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 ...

Amyloid
Amyloids are aggregates of proteins characterised by a Fibril, fibrillar morphology of 7–13 Nanometer, nm in diameter, a beta sheet (β-sheet) Secondary structure of proteins, secondary structure (known as cross-β) and ability to be Staining, stained by particular dyes, such as Congo red. In the human body, amyloids have been linked to the development of various diseases. Pathogenic amyloids form when previously healthy proteins lose their normal Protein structure, structure and physiology, physiological functions (Protein misfolding, misfolding) and form fibrous deposits in amyloid plaques around cells which can disrupt the healthy function of tissues and organs. Such amyloids have been associated with (but not necessarily as the cause of) more than 50 human diseases, known as amyloidosis, and may play a role in some neurodegenerative diseases. Some of these diseases are mainly sporadic and only a few cases are Genetic disorder, familial. Others are only Genetic disorder, fam ...
