Agaricus Impudicus
''Agaricus impudicus'', also known as the tufted wood mushroom, is a mushroom of ''Agaricus'', a genus with many edible species. Description As with all ''Agaricus'' species, gills are free, colour progresses with age from pale-pink to a chocolate color, and spores In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plant ... are dark brown. The stipe has a clear annulus (ring). Cap 4–15 cm wide, and appears brownish due to numerous brownish scales on a white background. The stipe is white, 6–12 cm tall and 0.8–2 cm thick, cylindrical and wider towards the bottom, or ending in a bulb. It is distinguished from similar forest-growing ''Agaricus'' mushrooms in that it does not bruise yellowish or reddish when cut, except for the attachment of stalk and cap which may tur ...

Carleton Rea
Carleton Rea (7 May 1861 – 26 June 1946) was an English mycologist, botanist, and naturalist. Background and education Carleton Rea was born in Worcester, the son of the City Coroner. He was educated at The King's School and Magdalen College, Oxford, where he studied law. He entered the Inner Temple and became a barrister in the Oxford Circuit, but never pursued his career with undue enthusiasm and ceased taking cases by 1907. Natural history and mycology In the words of John Ramsbottom, Rea was "active in his leisure" and devoted much of his time to natural history, having joined his local Worcestershire Naturalists' Club as a schoolboy (he was president of the club in its centenary year, at the time of his death). He collaborated with John Amphlett in the ''Botany of Worcestershire'', published in 1909, and wrote several later supplements. His first paper in 1892 was on rare plants of the Severn Valley. Rea's special interest was in fungi and in 1896 he was one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Pilát
Albert Pilát (November 2, 1903 – May 29, 1974) was a Czech botany, botanist and mycology, mycologist. He studied at the Faculty of Science at Charles University, under the guidance of Professor Josef Velenovský. In 1930, he joined the National Museum (Prague), National Museum, eventually becoming head of the Mycological Department, and in 1960 a corresponding member of the academy. He was the author of many popular and scholarly publications in the field of mycology and mountain flora. He also served as the editor-in-chief, main editor of the scientific journal ''Czech Mycology'', and described several species of fungi. His areas of particular interest include polypores and boletes. He explored the Carpathians looking for fungi and travelled widely. Between 1933 and 1948 he edited the exsiccata series ''Fungi Carpatici lignicoli exsiccati''. He was also a skilled photographer. In 1934, Josef Velenovský published in Monogr. Discom. Bohem. vol.35 on page 289, a genus of fungi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mushroom
A mushroom or toadstool is the fleshy, spore-bearing Sporocarp (fungi), fruiting body of a fungus, typically produced above ground on soil or another food source. ''Toadstool'' generally refers to a poisonous mushroom. 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 (mycology), stipe), a cap (Pileus (mycology), pileus), and gills (lamellae, sing. Lamella (mycology), 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. The gills produce microscopic Spore#Fungi, spores which help the fungus spread across the ground or its occupant surface. Forms deviating from the standard Morphology (biology), morphology usually have more specific names, such as "bolete", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agaricus
''Agaricus'' is a genus of mushroom-forming fungi containing both edible and poisonous species, with over 400 members worldwide and possibly again as many disputed or newly discovered species. The genus includes the common ("button") mushroom ('' A. bisporus'') and the field mushroom ('' A. campestris''), the dominant cultivated mushrooms of the West. Taxonomy Several origins of genus name ''Agaricus'' have been proposed. It possibly originates from ancient Sarmatia Europaea, where people Agari, promontory Agarum and a river Agarus were known (all located on the northern shore of Sea of Azov, probably, near modern Berdiansk in Ukraine). Note also Greek , agarikón, "a sort of tree fungus" (There has been an ''Agaricon'' Adans. genus, treated by Donk in ''Persoonia'' 1:180.) For many years, members of the genus ''Agaricus'' were given the generic name ''Psalliota'', and this can still be seen in older books on mushrooms. All proposals to conserve ''Agaricus' ...

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 Ploidy () is the number of complete sets of chromosomes in a cell (biology), cell, and hence the number of possible alleles for Autosome, autosomal and Pseudoautosomal region, pseudoautosomal genes. Here ''sets of chromosomes'' refers to the num ... nucleus (biology), nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidium, basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one Strain (biology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (ring) or cortina) or ...

Annulus (mushroom)
An annulus is the ring-like or collar-like structure sometimes found on the Stipe (mycology), stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gill (mushroom), gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species Species description, descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guides and on identification websites. Ring descriptions The way in which the structure and appearance of rings is described can vary with author and the description may only note the existence of a ring without providing specific information in cases where the ring lacks any notable features that ...

List Of Agaricus Species
The fungal genus ''Agaricus'' as late as 2008 was believed to contain about 200 species worldwide. Since then, molecular phylogenetic studies have revalidated several disputed species, as well as resolved some species complexes, and aided in discovery and description of a wide range of mostly tropical species that were formerly unknown to science. As of 2020, the genus is believed to contain no fewer than 400 species, and possibly many more. The medicinal mushroom known in Japan as ''Echigoshirayukidake'' (越後白雪茸) was initially also thought to be an ''Agaricus'', either a subspecies of ''Agaricus "blazei"'' (i.e. '' A. subrufescens''), or a new species. It was eventually identified as sclerotium of the crust-forming bark fungus '' Ceraceomyces tessulatus'', which is not particularly closely related to ''Agaricus''. Several secotioid (puffball-like) fungi have in recent times be recognized as highly aberrant members of ''Agaricus'', and are now included here. These typical ...

Fungi Described In 1932
A fungus (: fungi , , , or ; 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 one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 fungi'' or ''Eumycetes ...

Fungi Of New Zealand
The fungi of New Zealand consist of an estimated 22,000 species, of which only 34% are known. There is a high diversity of New Zealand native fungus, fungi, with about 1,100 species occurring in association with native ''Nothofagus'' or ''Metrosideros''. About a third of the known species are exotic, having been introduced by humans. Worldwide there is estimated to be over 1.5 million species according to the Hawksworth ratio of 1:6 (vascular plants to fungi). However, worldwide only 5% of these Taxon, taxa have been classified and extreme environments remain understudied. Of these known species there are 3,000 edible mushrooms, of which 200 are eaten by humans. All around the world mushrooms are prized as nutritious, tasty, and Bioactive compound, bioactive. New Zealand is no different. Humans settled in New Zealand after fungi had already established and began their settlement in conjunction with these organisms, first used by indigenous Māori people, Māori. This has result ...
