Leucocoprinus Flavescens
''Leucocoprinus flavescens'' is a species of mushroom-producing fungus in the family Agaricaceae. Taxonomy It was first described in 1907 by the American mycologist Andrew Price Morgan who classified it as ''Lepiota flavescens'' and reclassified as ''Leucocoprinus flavescens'' by the American botanist and mycologist Helen Vandervort Smith in 1981. Description ''Leucocoprinus flavescens'' is a small mushroom with very thin white to pale yellow flesh. Cap: 1–2.5cm or up to 4cm at the extreme. Ovoid to campanulate (bell shaped) with an umbo before flattening or becoming convex with age. The surface is pale greenish-yellow and is covered in fine powdery scales with smooth striations whilst the central disk is brownish but smooth. Stem: 2–6 cm and 1–2 mm in thickness with a slightly swollen base of 3–5 mm thick where white mycelium may be present. The stem surface is pale sulphur-yellow and is likewise covered with fine powdery scales like the cap though these may disap ...

Andrew Price Morgan
Andrew Price Morgan (27 October 1836 – 19 October 1907) was an American debater. He investigated the flora of the Miami Valley in Ohio. While his interest included flowering plants, as noted by his ''Flora of the Miami Valley, Ohio'', his special interest was in fungi. Morgan worked as a teacher in Dayton. He studied the botany of the Great Miami River, publishing in 1878 the ''Flora of the Miami River, Ohio''; Morgan also showed particular interest in mycology and bryology. A.P. Morgan was a mentor to the prominent American mycologist Curtis Gates Lloyd. His correspondence with Lloyd is stored in the Lloyd Library and Museum in Cincinnati. Lloyds portion of the correspondence is stored in the Ada Hayden Herbarium at Iowa state university. Morgans collection of preserved fungi can also be found at the Ada Hayden Herbarium along with Laura Morgans gouache illustrations of fungi that could not be preserved. Family Morgan married scientific illustrator and collector Laura Matil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agaricaceae
The Agaricaceae are a family of basidiomycete fungi and include the genus ''Agaricus'', as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae. Taxonomy The family Agaricaceae was published by French botanist François Fulgis Chevallier in 1826. It is named after the type genus ''Agaricus'', originally circumscribed by Carl Linnaeus in his 1753 work ''Species Plantarum''. In his authoritative 1986 classification of the Agaricales, Rolf Singer divided the Agaricaceae into four tribes distinguished largely by spore color: ''Leucocoprineae'', ''Agariceae'', ''Lepioteae'', and ''Cystodermateae''. Genera once classified in the families Tulostomataceae, Battarreaceae, Lycoperdaceae, and Mycenastraceae have since been moved to the Agaricaceae based on molecular phylogenetics studies. According to a standard reference text, the Agaricaceae contains 85 genera and 1340 species. Description Agaricaceae species use a wide variety o ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robinia
''Robinia'' is a genus of flowering plants in the family Fabaceae, tribe Robinieae, native to North America. Commonly known as locusts, they are deciduous trees and shrubs growing tall. The leaves are pinnate with 7–21 oval leaflets. The flowers are white or pink, in usually pendulous racemes. Many species have thorny shoots, and several have sticky hairs on the shoots. The genus is named after the royal French gardeners Jean Robin and his son Vespasien Robin, who introduced the plant to Europe in 1601. The number of species is disputed between different authorities, with as few as four recognised by some authors, while others recognise up to 10 species. Several natural hybrids are also known. Some species of ''Robinia'' are used as food by caterpillars of Lepidoptera, including such moths as the brown-tail (''Euproctis chrysorrhoea''), the buff-tip (''Phalera bucephala''), the engrailed (''Ectropis crepuscularia''), the giant leopard moth ('' Hypercompe scribonia''), the ...

Leucocoprinus Birnbaumii
''Leucocoprinus birnbaumii'' is a species of gilled mushroom in the family Agaricaceae. It is common in the tropics and subtropics. However, in temperate regions, it frequently occurs in greenhouses and flowerpots, hence its common names of flowerpot parasol and plantpot dapperling. It is considered to be toxic if consumed. Taxonomy The species was first described as ''Agaricus luteus'' in 1788 by the English mycologist James Bolton who described an observation from a hothouse near Halifax, three years earlier in 1785. Bolton also provided an illustration of the mushrooms. At the time gilled species were classified as ''Agaricus'' and ''luteus'' comes from the Latin for yellow or yellow-orange. Bolton suggested the common name of 'Yellow Cottony Agaric' in reference to the soft, scaly texture of the mushroom. However the name ''A. luteus'' had already been used to describe an unrelated ''Russula'' species and was published in 1778 by William Hudson so Bolton's ''A. ...
