Lepista Flaccida
''Paralepista flaccida'' (also called ''Clitocybe flaccida'', ''Clitocybe inversa'', ''Lepista flaccida'' and ''Lepista inversa'', or in English tawny funnel cap) is a species of mushroom found across the Northern Hemisphere. It is known to form fairy rings. Taxonomy The naming history of this mushroom is complicated by the fact that for a long time it was regarded as two different species, "''flaccida''" (associated with broad-leaved trees) and "''inversa''" (associated with conifers and with a smoother shinier cap). These forms can still be differentiated as varieties within ''P. flaccida'' if desired. The earliest description was by Giovanni Antonio Scopoli in 1772 as ''Agaricus inversus'' in his booFlora Carniolica then in 1799 James Sowerby created a description under the name ''Agaricus flaccidus'' in his major work ":commons:Coloured Figures of English Fungi or Mushrooms, Coloured Figures of English Fungi or Mushrooms". In later years there were defined the combinations '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Sowerby
James Sowerby (21 March 1757 – 25 October 1822) was an English natural history, naturalist, illustrator and mineralogist. Contributions to published works, such as ''A Specimen of the Botany of New Holland'' or ''English Botany'', include his detailed and appealing plates. The use of vivid colour and accessible texts was intended to reach a widening audience in works of natural history. Biography James Sowerby was born in Lambeth, London, his parents were named John and Arabella. Having decided to become a painter of flowers his first venture was with William Curtis, whose ''Flora Londinensis'' he illustrated. Sowerby studied art at the Royal Academy and took an apprenticeship with Richard Wright. He married Anne Brettingham De Carle and they were to have four daughters and three sons: James De Carle Sowerby (1787–1871), George Brettingham Sowerby I (1788–1854) and Charles Edward Sowerby (1795–1842), the Sowerby family of naturalists. His sons and theirs were to contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pileus (mycology)
In mycology (the branch of biology that includes the study of mushrooms and other fungi), the pileus is 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. The word ''pileus'' comes from the Latin for a type of felt cap. 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, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonsense Mutations
In genetics, a nonsense mutation is a point mutation in a sequence of DNA that results in a ''nonsense codon'', or a premature stop codon in the transcribed mRNA, and leads to a truncated, incomplete, and possibly nonfunctional protein product. Nonsense mutations are not always harmful; the functional effect of a nonsense mutation depends on many aspects, such as the location of the stop codon within the coding DNA. For example, the effect of a nonsense mutation depends on the proximity of the nonsense mutation to the original stop codon, and the degree to which functional subdomains of the protein are affected. As nonsense mutations leads to premature termination of polypeptide chains; they are also called chain termination mutations. Missense mutations differ from nonsense mutations since they are point mutations that exhibit a single nucleotide change to cause substitution of a different amino acid. A nonsense mutation also differs from a nonstop mutation, which is a point mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marcel Bon
Marcel Bon (17 March 1925 – 11 May 2014) was one of France's best known field mycologists. He was born in Picardy in 1925 and came to mycology through general botany, and pharmacology. He lived at Saint-Valery-sur-Somme, a quaint little town on the mouth of the river Somme, in Picardy, Northern France, which was a former artists' and writers' retreat, and is now a popular tourist town. In 1987, along with two artists (John Wilkinson, and Denys Ovenden) he produced a comprehensive field guide for mycologists, ''The Mushrooms and Toadstools of Britain and North-western Europe''. His other skills were as a pianist, an artist, and a skier. Bibliography *''The Mushrooms and Toadstools of Britain and North Western Europe'', Bon M., (1987) pub.

Saprobe
Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (e.g. ''Mucor'') and with soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes. - "The word saprophyte and its derivatives, implying that a fungus is a plant, can be replaced by saprobe (σαπρός + βίος), which is without such implication." Saprotrophic plants or bacterial flora are called saprophytes ( ''sapro-'' 'rotten material' + ''-phyte'' 'plant'), although it is now believed that all plants previously thought to be saprotrophic are in fact parasites of microscopic fungi or of other plants. In fungi, the saprotrophic process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae. states the purpose of sap ...

Paralepistopsis Amoenolens
''Paralepistopsis amoenolens'' is an agaric fungus in the Tricholomataceae family. It is commonly known as the paralysis funnel. Taxonomy It was first Species description, described in 1975 by the French mycologist Georges Jean Louis Malençon from a specimen found in Morocco and classified as ''Clitocybe amoenolens.'' In 2012, following DNA analysis, Vizzini and Ercole assigned this species to the new genus ''Paralepistopsis'', which forms a separate clade from other ''Clitocybe''s.See . The authors provide a phylogram which indicates the evidence that ''Paralepistopsis'' forms a separate clade. This change has been accepted by Index Fungorum and the Global Biodiversity Information Facility and so the correct name is currently ''Paralepistopsis amoenolens''. Toxicity It was discovered to be poisonous after several people had consumed specimens all found in the alpine Maurienne valley in the Savoie departments of France, department over three years. They had mistaken it fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infundibulicybe Gibba
''Infundibulicybe gibba'' (also known as ''Clitocybe gibba''), and commonly known as the common funnel or funnel cap, is a species of gilled mushroom which is common in European woods. Taxonomy The epithet ''gibba'' comes from the Latin adjective "gibbus", meaning "humped" or "gibbous". This species was originally described by the mycologist Christiaan Hendrik Persoon in 1801 as ''Agaricus gibbus'', at a time when gilled mushrooms were generally all assigned to genus ''Agaricus''. In 1871, Paul Kummer allocated the species to the genus ''Clitocybe'', which previously (according to the system of Elias Magnus Fries) had only been a tribe within genus ''Agaricus''. In 2003 Harri Harmaja created the new genus ''Infundibulicybe'' for some of the larger members of the former ''Clitocybe'' and he included ''I. gibba'' as the type species. ''Clitocybe catinus'' ''Clitocybe catinus'' is described as differing from ''C. gibba'' by having white cap with occasionally some pi ...

Paralepista Gilva
''Paralepista'' is a genus of mushrooms in family Tricholomataceae. Until 2012, its member species were generally assigned either to ''Lepista'' or to ''Clitocybe''. Naming history There have long been differing opinions as to how mushrooms which were assigned to genus ''Lepista'' (sometimes also placed in genus ''Clitocybe'') should be classified. The fungi in question all have a white or slightly pink/yellow spore print, finely warty spores, and easily separable gills. In 1981 Jörg H. Raithelhuber identified as separate a subgroup having very crowded strongly decurrent gills and spores which are oval in section to almost spherical, including ''Lepista flaccida'' and ''Lepista gilva''. He proposed this subgroup as a new genus ''Paralepista''. In the following years it was recognized at the level of a subgenus (also called "''Lepista'' section ''Inversae''" or "''Lepista'' sect. ''Gilva''), but not as a genus. Then in 2012 Alfredo Vizzini and Enrico Ercole published a paper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spore Print
300px, Making a spore print of the mushroom ''Volvariella volvacea'' shown in composite: (photo lower half) mushroom cap laid on white and dark paper; (photo upper half) cap removed after 24 hours showing warm orange ("tussock") color spore print. A 3.5-centimeter glass slide placed in middle allows for examination of spore characteristics under a microscope. The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it is easier to determine whether the spore print is pure white or, rather, very slightly pigmented. ...
