	Julius Schäffer Julius Schäffer (3 June 1882 – 21 October 1944) was a German mycologist. His contributions include studies on the Agaricales (gilled mushrooms), especially the genus ''Russula'', about which he wrote a monograph in 1933. Later, he revised the genus in the series ''Die Pilze Mitteleuropas'' (1926–1967); his notes were published posthumously by his wife Liesel in 1952 with the help of other mycologists. The work was considered the "authoritative treatment of the group for Central Europe". One of the ''Russula'' species that was first described in this publication was '' R. laeta''. Schäffer developed a chemical test to help with the identification of ''Agaricus'' species. A positive reaction of Schaeffer's test, which uses the reaction of aniline and nitric acid on the surface of the mushroom, is indicated by an orange to red color; it is characteristic of species in the section ''Flavescentes''. The compounds responsible for the reaction were named schaefferal A and B to honor Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Russula ''Russula'' is a very large genus composed of around 750 worldwide species of ectomycorrhizal mushrooms. They are typically common, fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include usually brightly coloured caps, a white to dark yellow spore print, brittle, attached gill (mushroom), gills, an absence of latex, and absence of partial veil or universal veil, volva tissue on the stem. Microscopically, the genus is characterised by the amyloid ornamented spores and flesh (trama) composed of spherocysts. Members of the related genus ''Lactarius (fungus), Lactarius'' have similar characteristics but emit a milky latex when their gills are broken. The genus was described by Christian Hendrik Persoon in 1796. Taxonomy Christian Hendrik Persoon first circumscription (taxonomy), circumscribed the genus ''Russula'' in his 1796 work ''Observationes Mycologicae'', and c ...

	Catalogue Of Life The Catalogue of Life is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, Encyclopedia of Life, and the Global Biodiversity Information Facility. The Catalogue currently compiles data fro165 peer-reviewed taxonomic databasesthat are maintained by specialist institutions around the world. , the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time. Structure The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological environment.

	Belgium Belgium, ; french: Belgique ; german: Belgien officially the Kingdom of Belgium, is a country in Northwestern Europe. The country is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the southwest, and the North Sea to the northwest. It covers an area of and has a population of more than 11.5 million, making it the 22nd most densely populated country in the world and the 6th most densely populated country in Europe, with a density of . Belgium is part of an area known as the Low Countries, historically a somewhat larger region than the Benelux group of states, as it also included parts of northern France. The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven. Belgium is a sovereign state and a federal constitutional monarchy with a parliamentary system. Its institutional organization is complex and is structured on both regional ...

picture info	Royal Belgian Institute Of Natural Sciences The Museum of Natural Sciences of Belgium (french: Muséum des sciences naturelles de Belgique, nl, Museum voor Natuurwetenschappen van België) is a museum dedicated to natural history, located in Brussels, Belgium. The museum is a part of the Royal Belgian Institute of Natural Sciences. Its most important pieces are 30 fossilised ''Iguanodon'' skeletons, which were discovered in 1878 in Bernissart, Belgium. The Dinosaur Hall of the museum is the world's largest museum hall completely dedicated to dinosaurs. Another famous piece is the Ishango bone, which was discovered in 1960 by Jean de Heinzelin de Braucourt in the Belgian Congo. The museum also houses a research department and a public exhibit department. History The Museum of Natural Sciences was founded on 31 March 1846, as a descendant of the ''Musée de Bruxelles'' of 1802. It was based on the collection established by Prince Charles Alexander of Lorraine, dating from the 18th century. The scientist and politician Be ...

picture info	Edible Fungi Edible mushrooms are the fleshy and edible fruit bodies of several species of macrofungi (fungi which bear fruiting structures that are large enough to be seen with the naked eye). They can appear either below ground (hypogeous) or above ground (epigeous) where they may be picked by hand. Edibility may be defined by criteria that include absence of poisonous effects on humans and desirable taste and aroma. Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor. Edible mushrooms include many fungal species that are either harvested wild or cultivated. Easily cultivated and common wild mushrooms are often available in markets, and those that are more difficult to obtain (such as the prized truffle, matsutake, and morel) may be collected on a smaller scale by private gatherers. Some preparations may render certain poisonous mushrooms fit for consumption. Before assuming that any wild mushroom is e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Fungi Described In 1952 A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
