Macrocybe Spectabilis
''Macrocybe spectabilis'' is a species of mushroom-forming fungus. It is found in Mauritius, Japan, and Hawaii. It is associated with sugarcane. It and '' Macrocybe titans'' contain large concentrations of cyanide In chemistry, cyanide () is an inorganic chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. Ionic cyanides contain the cyanide anion . This a ....

David Pegler
David Norman Pegler (born 2 November 1938) is a British mycologist who spent his entire professional career at Kew Gardens, where he became Head of Mycology and assistant keeper of the herbarium. A leading authority on tropical agarics, he described 11 new genera and over 180 species of fungi during expeditions to regions including East Africa, the Caribbean, and South America. He authored more than 200 scholarly articles and 35 books on fungal systematicswhilst also producing popular field guides, and received the Distinguished Mycologist Award from the Mycological Society of America upon his retirement in 1998. His contributions to mycology have been honoured with several species named after him and with two fungal genera, '' Pegleromyces'' and '' Peglerochaete''. Early life and education Pegler developed an interest in natural history during his childhood, joining natural history societies and bird-watching groups. This led to his fascination with fungi, which eventually shap ... [...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] |
Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), 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 motility, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauritius
Mauritius, officially the Republic of Mauritius, is an island country in the Indian Ocean, about off the southeastern coast of East Africa, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga, and St. Brandon (Cargados Carajos shoals). The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering approximately . The 1502 Portuguese Cantino planisphere has led some historians to speculate that Arab sailors were the first to discover the uninhabited island around 975, naming it ''Dina Arobi''. Called ''Ilha do Cirne'' or ''Ilha do Cerne'' on early Portuguese maps, the island was visited by Portuguese sailors in 1507. A Dutch fleet, under the command of Admiral Van War ...

Sugarcane
Sugarcane or sugar cane is a species of tall, Perennial plant, perennial grass (in the genus ''Saccharum'', tribe Andropogoneae) that is used for sugar Sugar industry, production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the Plant stem, stalk internodes. Sugarcanes belong to the grass family, Poaceae, an economically important flowering plant family that includes maize, wheat, rice, and sorghum, and many forage crops. It is native to New Guinea. Sugarcane was an ancient crop of the Austronesian people, Austronesian and Indigenous people of New Guinea, Papuan people. The best evidence available today points to the New Guinea area as the site of the original domestication of ''Saccharum officinarum''. It was introduced to Polynesia, Island Melanesia, and Madagascar in prehistoric times via Austronesian sailors. It was also introduced by Austronesian sailors to India and then to Southern China by 500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrocybe Titans
''Macrocybe titans'' is a species of mushroom native to Florida, Central and South America, This mushroom was described as ''Tricholoma titans'' in 1980 by Howard E. Bigelow and J. W. Kimbrough, before being reclassified in ''Macrocybe ''Macrocybe'' is a genus of fungi in the family Callistosporiaceae. Basidiocarps (fruit bodies) are agarics (gilled mushrooms) and were previously referred to ''Tricholoma'', but are all large, whitish, and saprotrophic (''Tricholoma'' species ar ...'' in 1998. ''Macrocybe titans'' form solid, large mushrooms that grow in clumps. The cap is from across, with rare specimens up to in diameter. Buff-ochre with a darker centre and greyish at the margins, and becoming white with age. The crowded white to pale grey or pale brown gills are sinuate and up to 2 cm thick. The cylindrical stout white stem is high and across with a swollen base up to in diameter. Rare specimens have stems up to high and wide. References External links *' ...

Cyanide
In chemistry, cyanide () is an inorganic chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. Ionic cyanides contain the cyanide anion . This anion is extremely poisonous. Soluble cyanide salts such as sodium cyanide (NaCN), potassium cyanide (KCN) and tetraethylammonium cyanide () are highly toxic. Covalent cyanides contain the group, and are usually called nitriles if the group is linked by a single covalent bond to carbon atom. For example, in acetonitrile , the cyanide group is bonded to methyl . In tetracyanomethane , four cyano groups are bonded to carbon. Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus toxic. The cyano group may be covalently bonded to atoms different than carbon, e.g., in cyanogen azide , phosphorus tricyanide and trimethylsilyl cyanide . Hydrogen cyanide, or , is a highly volatile toxic liquid tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
