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 Onusta 59483
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, '' A. basii'' and similar species in Mexico, '' A. caesarea'' and the "Blusher" '' Amanita rubescens'' in Europe, and '' A. chepangiana'' in South-East Asia. Other species are used for colouring sauces, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pileus (mycology)
The pileus is the technical name for the cap, or cap-like part, of a basidiocarp or ascocarp (fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium (hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various ''Amanita'' species and boletes. Some, such as the parasol mushroom, have distinct bosses or umbos and are described as ''umbonate''. An umbo is a knobby protrusion at the center of th ...

Basidiocarp
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye (especially those with a more or less agaricoid morphology) are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles. Structure All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi. In more complex basidiocarps, there is differentiation into a stipe, a pileus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Amanita Sphaerobulbosa
''Amanita sphaerobulbosa'', commonly known as the Asian abrupt-bulbed Lepidella, is a species of agaric fungus in the family Amanitaceae. First described by mycologist Tsuguo Hongo in 1969, it is found in Southern Asia. The species was formerly consider synonymous with the North American lookalike '' Amanita abrupta'', but that species has narrower spores, a persistent partial veil, and lacks the refractive contents found in the hyphae and inflated cells of ''A. sphaerobulbosa''. The fruit bodies of ''Amanita sphaerobulbosa'' are damaging to the liver; the toxicity is thought to be largely due to a rare amino acid. Although not considered as toxic as its infamous relatives the death cap and the destroying angel, ''A. sphaerobulbosa'' is blamed for the deaths of two Japanese women in 1978. Poisoning symptoms included the abrupt appearance of violent vomiting, diarrhea and dehydration after a delay of 10–20 hours. Habitat and distribution The mushroom has been co ...

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 ...

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] |
