Russula Raoultii
''Russula raoultii'' is an inedible species of agaric fungus in the family Russulaceae. It was first species description, described by French mycologist Lucien Quélet in 1886. The cap is 3 to 8 cm wide, white to yellow, and becoming more convex in age. The stalk is 3 to 8 cm long and 1 to 2 cm wide. The spores are white, subglobose, with reticular warts. It has an acrid taste. Similar species include ''Russula crassotunicata'', ''R. cremoricolor'', and ''R. stuntzii''.

Rolf Singer
Rolf Singer (June 23, 1906 – January 18, 1994) was a German-born mycologist and one of the most important taxonomists of gilled mushrooms (agarics) in the 20th century. After receiving his Ph.D. at the University of Vienna in 1931 he worked in Munich. By 1933, however, Singer left Germany for Vienna due to the political deterioration in Germany. There he met his wife, Martha Singer. From Vienna, Singer and his wife went to Barcelona, Spain, where Singer was appointed assistant professor at the Autonomous University of Barcelona. Persecution by the Spanish authorities on behalf of the German government forced Singer to leave Spain for France in 1934. After a fellowship at the Museum d'Histoire Naturelle in Paris, Singer again moved, this time to Leningrad, where he was Senior Scientific Expert at the Botanical Garden of the Academy of Sciences of the USSR. During his time at the Academy, Singer made many expeditions to Siberia, the Altai Mountains, and Karelia. In 1941, Sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agaric
An agaric () is a type of fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. In the UK, agarics are called "mushrooms" or "toadstools". In North America they are typically called "gilled mushrooms". "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically, agaric meant 'tree-fungus' (after Latin ''agaricum''); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name '' Agaricus'' for gilled mushrooms. Most species of agaricus belong to the order Agaricales in the subphylum Agaricomycotina. The exceptions, where agarics have evolved independently, feature largely in the orders Russulales, Boletales, Hymenochaetales, and several other groups of basidiomycetes. Old systems of classification placed all agarics in the Agaricales and some (mostly older) sour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russulaceae
The Russulaceae are a diverse family of fungi in the order Russulales, with roughly 1,900 known species and a worldwide distribution. They comprise the brittlegills and the milk-caps, well-known mushroom-forming fungi that include some edible species. These gilled mushrooms are characterised by the brittle flesh of their fruitbodies. In addition to these typical agaricoid forms, the family contains species with fruitbodies that are laterally striped (pleurotoid), closed ( secotioid or gasteroid), or crust-like (corticioid). Molecular phylogenetics has demonstrated close affinities between species with very different fruitbody types and has discovered new, distinct lineages. An important group of root- symbiotic ectomycorrhizal fungi in forests and shrublands around the world includes ''Lactifluus'', '' Multifurca'', ''Russula'', and ''Lactarius''. The crust-forming genera '' Boidinia'', '' Gloeopeniophorella'', and '' Pseudoxenasma'', all wood-decay fungi, have basal posi ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucien Quélet
Lucien Quélet in 1869 Lucien Quélet (14 July 1832 – 25 August 1899) was a French naturalist and mycologist. Quélet discovered several species of fungi and was the founder of the Société mycologique de France, a society devoted to mycological studies. Quélet, having been born in Montécheroux, Doubs, to a farmer, was soon orphaned, and spent his childhood with and was raised by his aunts. In his youth, he is known to have shown a great interest in mycology and botany in general, but also other subject areas such as ornithology and malacology, the study of mollusks. He was schooled at the Montbéliard college, and later studied medicine in Strasbourg. In 1884, he founded the mycological society known as the Société mycologique de France, of which he became the first president. Several years after this, in 1888, Quélet wrote a book, ''Flore mycologique de la France et des pays limitrophes'' (''Mycological flora of France and neighbouring countries''). Quélet al ...

MycoBank
MycoBank is an online database, documenting new mycological names and combinations, eventually combined with descriptions and illustrations. It is run by the Westerdijk Fungal Biodiversity Institute in Utrecht. Each novelty, after being screened by nomenclatural experts and found in accordance with the ICN (International Code of Nomenclature for algae, fungi, and plants), is allocated a unique MycoBank number before the new name has been validly published. This number then can be cited by the naming author in the publication where the new name is being introduced. Only then, this unique number becomes public in the database. By doing so, this system can help solve the problem of knowing which names have been validly published and in which year. MycoBank is linked to other important mycological databases such as ''Index Fungorum ''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Roy ...

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 gills, an absence of latex, and absence of partial veil or 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'' 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 circumscribed the genus ''Russula'' in his 1796 work ''Observationes Mycologicae'', and considered the defining characteristics to be the fleshy fruit bodies, depre ...
