Agaricus Silvicola
''Agaricus silvicola'', also known as the wood mushroom, is a species of Agaricus mushroom related to the button mushroom. Taxonomy Originally described as the variety ''Agaricus campestris'' var. ''silvicola'' by Carlo Vittadini in 1832, it was promoted to distinct species status by Charles Horton Peck in 1873. Varieties with larger bases have been described as '' A. abruptibulbus''. Description The cap is light cream, and bruises yellow ochre when damaged. It is in diameter, which makes it slightly smaller than its close relative ''Agaricus arvensis'', the "horse mushroom". The stem is , and usually has a bulbous base. It is much the same colour as the cap, and has a fragile drooping ring. The flesh is thin and white, and smells of aniseed. It looks fairly similar to a young death cap. The spores are brown, elliptical, and smooth. Distribution and habitat ''Agaricus silvicola'' grows in both deciduous and coniferous woodland in Britain, Europe, and North America. Appe ...

Carlo Vittadini
Carlo Vittadini (11 June 1800, in Bertonico – 20 November 1865, in Milan) was an Italian physician, doctor and mycology, mycologist. Life He studied in Milan and at the University of Pavia, where he attended the classes given by Giuseppe L. Moretti (1782–1853). He became a doctor of medicine in 1826 with a thesis entitled ''Tentamen mycologicum seu Amanitarum '' where he described 14 species of the genus ''Amanita''. Outside of several publications on diseases of silkworms, he specialised in obstetrics, working in Milan. He is the author of several important works on Italian mushroom species. Works * * ''Monographia tuberacearum'' (Rusconi, Milan, 1831) - Describes 65 species, of which 51 were new. * ''Descrizione dei funghi mangerecci più comuni dell'Italia e de'velenosi che possono co'medesimi confondersi'' (1835) - Describes 56 species, of which 15 were new. * ''Monographia Lycoperdineorum'' (1842) - Completes his 1831 study and describes 50 species, of which 2 ...

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 nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one 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 five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...

Fungi Described In 1832
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 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 organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
