Russula Foetens
Russula foetens, commonly known as the stinking russula, is a common ''Russula'' mushroom found in deciduous and coniferous forests. Description The cap is hemispherical and very slimy when young, soon convex, honey yellow to ochre brown and up to 10 cm (4 in) in diameter. The gills and spores are pale cream. The strong stem is white or blotchy yellowish brown. The flesh has a strong acrid smell, when old it has a fishy smell and bad taste. Edibility Stinking russula is widely considered inedible. In countries like Russia it is used for traditional mushroom pickles after being soaked in water for several days to remove the strong taste, as with all other ''Russula'' species. Such preservation method allows the use of many otherwise inedible russulas and milk-cap Milk-cap (also milk cap, milkcap, or milky) is a common name that refers to mushroom-forming fungi of the genera ''Lactarius'', '' Lactifluus'', and '' Multifurca'', all in the family Russulaceae.

Christiaan Hendrik Persoon
Christiaan Hendrik Persoon (31 December 1761 – 16 November 1836) was a Cape Colony mycologist who is recognized as one of the founders of mycology, mycological Taxonomy (biology), taxonomy. Early life Persoon was born in Cape Colony at the Cape of Good Hope, the third child of an immigrant Pomeranian father, Christiaan Daniel Persoon, and Netherlands, Dutch mother, Wilhelmina Elizabeth Groenwald. His mother died soon after he was born. In 1775, at the age of thirteen, he was sent to Europe for his education. His father died a year later in 1776. Education Initially a student of theology at University of Halle-Wittenberg, Halle, Persoon switched his studies to medicine, which he pursued in Leiden and then Göttingen. He received a doctorate from the German National Academy of Sciences Leopoldina, Deutsche Akademie der Naturforscher in Erlangen 1799. Later years He moved to Paris by 1803, where he spent the rest of his life, renting the upper floor of a house in a poor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russula
''Russula'' is a very large genus composed of around 750 worldwide species of fungi. The genus was described by Christian Hendrik Persoon in 1796. The mushrooms are 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 ectomycorrhizal mushrooms are typically common. Although some species are toxic, a number of others are edible. Taxonomy Christian Hendrik Persoon first circumscribed the genus ''Russula'' in his 1796 work ''Observationes Mycologi ...

Pileus (mycology)
In mycology (the branch of biology that includes the study of mushrooms and other fungi), the pileus is the cap or cap-like part of a basidiocarp or ascocarp ( fungal fruiting body) that supports a spore-bearing surface, the hymenium.Moore-Landecker, E: "Fundamentals of the Fungi", page 560. Prentice Hall, 1972. The hymenium ( hymenophore) may consist of lamellae, tubes, or teeth, on the underside of the pileus. A pileus is characteristic of agarics, boletes, some polypores, tooth fungi, and some ascomycetes. The word ''pileus'' comes from the Latin for a type of felt cap. Classification Pilei can be formed in various shapes, and the shapes can change over the course of the developmental cycle of a fungus. The most familiar pileus shape is hemispherical or ''convex.'' Convex pilei often continue to expand as they mature until they become flat. Many well-known species have a convex pileus, including the button mushroom, various ''Amanita'' species and boletes. Some, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milk-cap
Milk-cap (also milk cap, milkcap, or milky) is a common name that refers to mushroom-forming fungi of the genera ''Lactarius'', '' Lactifluus'', and '' Multifurca'', all in the family Russulaceae. The common and eponymous feature of their fruitbodies is the latex ("milk") they exude when cut or bruised. Mushrooms with typical milk-cap characteristics are said to have a lactarioid habit. Some of them are edible. Historically, these species were all united in the genus ''Lactarius'', but molecular phylogenetic analysis has shown that they belong in fact to three distinct clades: * ''Lactarius'' holds most of the milk-caps known from the Northern hemisphere. * '' Lactifluus'' contains mainly tropical species, but also some well known northern milk-caps. * '' Multifurca'' contains only one species exuding milk, '' M. furcata'' from North and Central America. Some prominent species *''Lactarius deliciosus'' - "saffron milk-cap" or "red pine mushroom" *''Lactarius deterrimus'' - ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fungi Of Europe
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), 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 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
