René Maire
René Charles Joseph Ernest Maire (29 May 1878, Lons-le-Saunier – 24 November 1949) was a French botanist and mycologist. His major work was the ''Flore de l'Afrique du Nord'' in 16 volumes published posthumously in 1953. He collected plants from Algeria, Morocco, France, and Mali for the herbarium of the National Botanic Garden of Belgium. Biography His botanical career began very early. At 18, he penned a work on the local flora of the Haute-Saône, currently on display at the Natural History Museum of Gray. He collected plants for study in Algeria and Morocco between 1902 and 1904. After obtaining his PhD in 1905, he was a professor of botany at the Faculty of Sciences in Algiers starting in 1911 where he specialised in phytopathology. He was put in charge of botanical research by the Moroccan government and was responsible for botanical studies in the Central Sahara. He was a member of a number of institutions, including the ''Société mycologique de France'' and the ''Soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hygrophorus Reai
''Hygrophorus'' is a genus of agarics (gilled mushrooms) in the family Hygrophoraceae. Called "woodwaxes" in the UK or "waxy caps" (together with ''Hygrocybe'' species) in North America, basidiocarps (fruit bodies) are typically fleshy, often with slimy caps and lamellae that are broadly attached to decurrent. All species are ground-dwelling and ectomycorrhizal (forming an association with living trees) and are typically found in woodland. Around 100 species are recognized worldwide. Fruit bodies of several species are considered edible and are sometimes offered for sale in local markets. Taxonomy History ''Hygrophorus'' was first published in 1836 by Swedish mycologist Elias Magnus Fries. The generic name is derived from the Greek ῦγρὁς (= moist) + φόρος (= bearer), with reference to the slimy caps found in many species. Fries (1849) subsequently split the genus into three subgenera: ''Limacium'', ''Camarophyllus'', and ''Hygrocybe''. The last of these is now recogn ...

Russula Mairei
Formerly ''Russula mairei'' (Singer), and commonly known as the beechwood sickener, the now re-classified fungus ''Russula nobilis'' (Velen.) is a basidiomycete mushroom of the genus ''Russula''. This group of mushrooms are noted for their brittle gills and bright colours. Taxonomy It was previously named in honour of French mycologist René Maire by Rolf Singer in 1929, but found to be the same taxon as the earlier 1920 ''Russula nobilis'', which has naming priority. Description The cap is a red or rosy colour, 3–6 cm wide, convex to flat, or slightly depressed, and weakly sticky. It peels only to a third of its radius, which reveals pink flesh. The flesh is firm and white or sometimes yellowish, smells of coconut, and tastes peppery. It is often damaged by slugs. The stem is 2–5 cm long, 1–1.5 cm wide, cylindrical, (firmer than its conifer dwelling namesake, ''Russula emetica''), and white. The gills are narrowly spaced, adnexed, rounded, and white, oft ...

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boletus
''Boletus'' is a genus of mushroom-producing fungi, comprising over 100 species. The genus ''Boletus'' was originally broadly defined and described by Carl Linnaeus in 1753, essentially containing all fungi with hymenial pores instead of gills. Since then, other genera have been defined gradually, such as ''Tylopilus'' by Petter Adolf Karsten in 1881, and old names such as ''Leccinum'' have been resurrected or redefined. Some mushrooms listed in older books as members of the genus have now been placed in separate genera. These include such as ''Boletus scaber'', now ''Leccinum scabrum'', ''Tylopilus felleus'', ''Chalciporus piperatus'' and ''Suillus luteus''. Most boletes have been found to be ectomycorrhizal fungi, which mean that they form a mutualistic relationship with the roots system of certain kinds of plants. More recently, ''Boletus'' has been found to be massively polyphyletic, with only a small percentage of the over 300 species that have been assigned to ''Boletus' ...

Gyrodon
''Gyrodon'' is a genus of pored mushroom bearing close affinity to the genus ''Paxillus''. Recent molecular research has confirmed this relationship of the two genera as sister taxa, together diverging as one of the most basal lineages in the Boletineae, and sister to the Boletaceae. ''Gyrodon'' was circumscribed by German botanist Wilhelm Opatowski in 1836. Species , Index Fungorum lists 13 species of ''Gyrodon''. See also *''Boletinellus merulioides ''Boletinellus merulioides'', commonly known as the ash-tree bolete, is a species of bolete fungus in the family Boletinellaceae .

Paxillus
''Paxillus'' is a genus of mushrooms of which most are known to be poisonous or inedible. Species include '' Paxillus involutus'' and '' Paxillus vernalis''. Two former species—''Tapinella panuoides'' and ''Tapinella atrotomentosa''—have now been transferred to the related genus '' Tapinella'' in the family Tapinellaceae Binder M, Larsson KH, Matheny PB, Hibbett DS. 2010. Amylocorticiales ord. nov. and Jaapiales ord. nov.: Early diverging clades of Agaricomycetidae dominated by corticioid forms. Mycologia 102:865. ''Paxillus'' means ''small stake''. Edibility While this genus has in the past been erroneously considered edible, it is now known to be poisonous and has been linked to a number of recorded fatalities. The deadly poisonings appear to have been due to eating the mushrooms raw.

Bolete
{{refimprove, date=July 2020 A bolete is a type of mushroom, or fungal fruiting body. It can be identified thanks to a unique mushroom cap. The cap is clearly different from the stem. On the underside of the cap there is usually a spongy surface with pores, instead of the gills typical of mushrooms. However, there are some boletes that are gilled, such as species of ''Chroogomphus'', '' Gomphidius'', ''Paxillus'', ''Phylloporus'' and ''Hygrophoropsis aurantiaca''. "Bolete" is the English common name for fungus species whose mushroom caps have this appearance. The boletes are classified in the order Boletales. Not all members of the order Boletales are boletes. The micromorphology and molecular phylogeny of the order Boletales have established that it also contains many gilled, puffball, and other fruit body shapes. A similar pore surface is found in polypores, but these species generally have a different physical structure from boletes, and have different microscopic chara ...

Paxillaceae
The Paxillaceae are a family of mushroom-forming fungi bearing close affinity to the boletes. Collectively, the family contains nine genera and 78 species. The type genus is ''Paxillus'', containing fungi with decurrent gills, and ''Gyrodon'', which has members with decurrent pores, among others. French mycologist René Maire had erected the family in 1902, placing it between the agarics and boletes and recognizing the groups' similarities with the latter group. Maire's usage of the name was later deemed to be invalid, and the genus authority is attributed to Johannes Paulus Lotsy. Molecular research confirms the relations of ''Gyrodon'', with the decurrent-pored mushroom '' G. lividus'', ''Paragyrodon'', with the type species ''P. sphaerosporus'', and ''Paxillus'' as sister groups, together lying near the base of a phylogenetic tree from which the genus ''Boletus'' arises. The name Gyrodontaceae, published by Belgian botanist Paul Heinemann in 1951, is considered synony ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xeromphalina Campanella
''Xeromphalina campanella'' is a species of mushroom. The common names of the species include the golden trumpet and the bell Omphalina. The genus name ''Xeromphalina'' means "little dry navel" and ''campanella'' means "bell-shaped", respectively describing the mature and young shapes of the ''pileus'', or cap. The mushroom is also called ''fuzzy-foot''. Description The fruit body of ''X. campanella'' has a small umbrella-shaped cap, about .5–2 cm wide. The thin brown stalk is 1–5 cm long and 1–3 mm wide, yellow at the apex, reddish brown below, with brown or yellow hairs at the base. The gills are pale yellow to pale orange. The spore print is pale buff. When the species is young, their caps are bell-shaped. As they mature, the outer part of the cap expands and rises which leaves the center depressed, resembling a navel. Edibility Although the species is not poisonous, the mushrooms are small and bitter tasting with no value as edibles. David Arora suggests that t ...

Psathyrella Hydrophila
''Psathyrella'' is a large genus of about 400 species, and is similar to the genera ''Coprinellus'', ''Coprinopsis'', ''Coprinus'' and ''Panaeolus'', usually with a thin cap and white or yellowish white hollow stem. The caps do not self digest as do those of ''Coprinellus'' and ''Coprinopsis''. Some also have brown spores rather than black. These fungi are often drab-colored, difficult to identify, and all members are considered inedible or worthless (for eating) and so they are often overlooked. However they are quite common and can occur at times when there are few other mushrooms to be seen. The first report of a gilled mushroom fruiting underwater is ''Psathyrella aquatica''. The genus name ''Psathyrella'' is a diminutive form of ''Psathyra'', derived from the Greek word ψαθυρος, ''psathuros'' 'friable'. The type species of ''Psathyrella'' is ''Psathyrella gracilis'', which is now known as ''Psathyrella corrugis''. Characteristics In order to identify the species it ...

Psathyrella Candolleana
''Candolleomyces candolleanus'' (formerly known as ''Psathyrella candolleana'') is mushroom in the family Psathyrellaceae. It is commonly found growing in small groups around stumps and tree roots on lawns and pastures in Europe and North America. In 2014, it was reported from Iraq. The coloring varies between white and golden brown. The cap is tan when young, growing to in diameter, initially conical, later becoming rounded and finally with upturned margins in maturity. The cap margin is irregular and radially asymmetrical—a defining characteristic of this species. It can retain veil fragments on the edge and center. The white stalk is tall and 3–7 mm wide. The spore print is purple-brown, while spores are smooth and elliptical, measuring 6.5–8 by 4–5 µm. The specific epithet ''candolleanus'' honors Swiss botanist Augustin Pyramus de Candolle Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist.
