Macrolepiota Albuminosa
''Macrolepiota albuminosa'' is a species of agaric fungus in the family Agaricaceae, found in Peradeniya, Ceylon (now Sri Lanka). In 1847, English mycologist Miles Joseph Berkeley scientifically described it and named it ''Agaricus albuminosus''. It was transferred to the genus '' Termitomyces'' in 1941 by the French botanist Roger Heim. In 1972, British mycologist David Pegler reexamined the specimen, and moved it to ''Macrolepiota ''Macrolepiota'' is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (''M. procera''). The widespread genus contains about 40 species. Taxonomy ''Macrolepiota'' was circu ...''. Frequently, the name ''Collybia albuminosa'' is misused for '' Termitomyces eurrhizus'', and the name ''Termitomyces albuminosus'' for '' Termitomyces'' mushrooms. Termitomycesphins A-H are neuritogenic cerebrosides isolated from the fungus. References External links * * {{Taxonbar, from=Q139 ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Described In 1847
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 ...

Index Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are '' MycoBank'' and '' Fungal Names''. As of 2023, over a millio ...

Cerebroside
Cerebrosides (monoglycosylceramides) are a group of glycosphingolipids which are important components of animal muscle and nerve cell membranes. They consist of a ceramide with a single sugar residue at the 1-hydroxyl moiety. The sugar residue can be either glucose or galactose; the two major types are therefore called glucocerebrosides (a.k.a. glucosylceramides) and galactocerebrosides (a.k.a. galactosylceramides). Galactocerebrosides are typically found in neural tissue, while glucocerebrosides are found in other tissues. Structure The fundamental structure of a cerebroside is ceramide. Monoglycosyl and oligoglycosylceramides having a mono or polysaccharide bonded glycosidically to the terminal OH group of ceramide are defined as cerebrosides. Sphingosine is the main long-chain base present in ceramide. Galactosylceramide is the principal glycosphingolipid in brain tissue. Galactosylceramides are present in all nervous tissues, and can compose up to 2% dry weight of grey m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termitomyces Eurrhizus
''Termitomyces eurrhizus'' species of agaric fungus in the family Lyophyllaceae native to Pakistan, India, Sri Lanka, Burma, southwestern China and Malaysia. The fungus has a symbiotic relationship with termites, its mushrooms growing out of mounds after periods of rainfall. It is eaten in Malaysia and the Indian subcontinent. Taxonomy Miles Joseph Berkeley named the fungus in 1847 as ''Agaricus eurrhizus'', from material collected in Peradeniya in Sri Lanka. French botanist Roger Heim reclassified the species as ''Termitomyces eurrhizus'' in 1942. Its place in ''Termitomyces'' was confirmed with a 2000 ribosomal DNA study showing that the termite mushrooms form a clade. Description The cap is from 6–15 cm across, with rare specimens up to 24 cm in diameter. Grey-brown and fading to whitish at the margins, the cap is initially convex before expanding out with a central boss. The crowded white gills are free to subadnate. The ringless stout white stem is up to 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrolepiota
''Macrolepiota'' is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (''M. procera''). The widespread genus contains about 40 species. Taxonomy ''Macrolepiota'' was circumscribed by Rolf Singer in 1948, with ''Macrolepiota procera'' as the type species. DNA studies have split this genus into three clades. The macrolepiota clade includes ''M. procera, M. clelandii'', ''M. dolichaula'' and closely related species. The macrosporae clade includes species such as ''M. mastoidea'', ''M. konradii'', and ''M. orientiexcoriata'', while the volvatae clade includes ''M. velosa'' and ''M. eucharis''. Uses ''Macrolepiota procera'', the parasol mushroom, is a well-known and highly esteemed edible species in much of Europe.Parasol Mushroom - Private mushroom record of Józef Bossowski Species , Index Fungorum accepts 42 species of ''Macrolepiota'': *'' Macrolepiota africana'' ( ...

Roger Heim
Roger Heim (February 12, 1900 – September 17, 1979) was a French botanist specialising in mycology and tropical phytopathology. He was known for his studies describing the anatomy of the mushroom hymenium, the systematics and phylogeny of higher fungi (especially the related genera ''Lactarius'' and '' Russula'', the Russulales and '' Secotium''), the mycology of tropical fungi such as '' Termitomyces'', as well as ethnomycological work on hallucinogenic fungi, like ''Psilocybe'' and '' Stropharia''. In his career, he published over 560 articles, scientific reviews, and major works in fields like botany, chemistry, education, forestry, horticulture, liberal arts, medicine and zoology.Batra, L.R.

Termitomyces
''Termitomyces'' is a genus of the termite mushrooms, the basidiomycete fungi belonging to the family Lyophyllaceae. ''Termitomyces'' fungi and fungus-farming termites (Macrotermitinae) co-depend to survive, as the termites house and culture the fungi, and the fungi in turn provide foods for the termites. ''Termitomyces'' mushrooms are edible, and are highly regarded for their flavor. Morphology ''Termitomyces'' includes the largest edible mushroom in the world, ''Termitomyces titanicus'' of West Africa and Zambia, whose cap reaches 1 metre (3.28 ft) in diameter. It also includes '' Termitomyces microcarpus'' that grows caps of a few centimeters in diameter. Life as a ''Termitomyces'' fungus These fungi grow on 'combs' which are formed from the termites' excreta, dominated by tough woody fragments. Some chamber(s) of the nest each contains a structure, called comb or fungus garden, where the fungus dwells. The termites collect and chew up dead wood, leaf litter and oth ...

Miles Joseph Berkeley
Miles Joseph Berkeley (1 April 1803 – 30 July 1889) was an English cryptogamist and clergyman, and one of the founders of the science of plant pathology. Life Berkeley was born at Biggin Hall, Benefield, Northamptonshire, and educated at Rugby School and Christ's College, Cambridge. Taking holy orders, he became incumbent of Apethorpe in 1837, and vicar of Sibbertoft, near Market Harborough, in 1868. He acquired an enthusiastic love of cryptogamic botany (lichens) in his early years, and soon was recognized as the leading British authority on fungi and plant pathology. Christ's College made him an honorary fellow in 1883. He was well known as a systematist in mycology with some 6000 species of fungi being credited to him, but his ''Introduction to Cryptogamic Botany'', published in 1857, and his papers on Vegetable Pathology in the ''Gardener's Chronicle'' in 1854 and onwards, show that he had a broad grasp of the whole domain of physiology and morphology as understood ...
