Stinkhorn
Phallaceae is a family of fungi, commonly known as stinkhorns, within the order Phallales. Stinkhorns have a worldwide distribution, but are especially prevalent in tropical regions. They are known for their foul-smelling, sticky spore masses, or gleba, borne on the end of a stalk called the receptaculum. The characteristic fruiting-body structure, a single, unbranched receptaculum with an externally attached gleba on the upper part, distinguishes the Phallaceae from other families in the Phallales. The spore mass typically smells of carrion or dung, and attracts flies, beetles and other insects to help disperse the spores. Although there is great diversity in body structure shape among the various genera, all species in the Phallaceae begin their development as oval or round structures known as "eggs". According to a 2008 estimate, the family contains 21 genera and 77 species. Description Species of stinkhorns have gasteroid, or internally produced spores. Fruit bodies origin ...

Phallus (fungus)
The genus ''Phallus'', commonly known as stinkhorns, is a group of basidiomycetes which produce a phallic, often foul-scented, mushroom, from which their name is derived. The genus has a widespread distribution and, according to a 2008 estimate, contains 18 species. They belong to the family Phallaceae in the order Phallales. The best known species (and type species) is the common stinkhorn (''Phallus impudicus''). History and taxonomy The genus was first mentioned in the literature by the Dutch botanist Hadrianus Junius (1511–1575), who, in 1564 wrote a short book published in Delft on the ''Phallus in Hollandia'', describing a mushroom in the form of a penis. He was not convinced that the organism was fungal in nature:... I am not sure that our Phallus falls within the class of the fungi. I will not definitely decide to place it there because I do not want to make a judgment before others who know more about the matter. The lightness, however, and looseness of the substance ...

Phallus Impudicus
''Phallus impudicus'', known colloquially as the common stinkhorn, is a widespread fungus in the Phallaceae (stinkhorn) family. It is recognizable for its foul odor and its phallic shape when mature, the latter feature giving rise to several names in 17th-century England. It is a common mushroom in Europe and North America, where it occurs in habitats rich in wood debris such as forests and mulched gardens. It appears from summer to late autumn. The fruiting structure is tall and white with a slimy, dark olive colored conical head. Known as the gleba, this material contains the spores, and is transported by insects which are attracted by the odor—described as resembling carrion. Despite its foul smell, it is not usually poisonous and immature mushrooms are consumed in parts of France and Germany. Taxonomy The Italian naturalist Ulisse Aldrovandi described the fungus in 1560 with name ''fungus priapeus'', and he depicted it in his series of water-coloured plates called ''teat ...

Clathrus Ruber
''Clathrus ruber'' is a species of fungus in the family Phallaceae, and the type species of the genus '' Clathrus''. It is commonly known as the latticed stinkhorn, the basket stinkhorn, or the red cage, alluding to the striking fruit bodies that are shaped somewhat like a round or oval hollow sphere with interlaced or latticed branches. The fungus is saprobic, feeding off decaying woody plant material, and is often found alone or in groups in leaf litter on garden soil, grassy places, or on woodchip garden mulches. Although considered primarily a European species, ''C. ruber'' has been introduced to other areas, and now has a wide distribution that includes all continents except Antarctica. The species was illustrated in the scientific literature during the 16th century, but was not officially described until 1729. The fruit body initially appears like a whitish "egg" attached to the ground at the base by cords called rhizomorphs. The egg has a delicate, leathery out ...

Carrion
Carrion () is the decaying flesh of dead animals, including human flesh. Overview Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eaters (or scavengers) include crows, vultures, condors, hawks, eagles, hyenas, Virginia opossum, Tasmanian devils, coyotes and Komodo dragons. Many invertebrates, such as the carrion and burying beetles, as well as maggots of calliphorid flies (such as one of the most important species in '' Calliphora vomitoria'') and flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains. Carrion begins to decay at the moment of the animal's death, and it will increasingly attract insects and breed bacteria. Not long after the animal has died, its body will begin to exude a foul odor caused by the presence of bacteria and the emission of cadaverine and putrescine. Some plants and fungi smell like decomposing carrion and attract insects that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasteroid
The gasteroid fungi are a group of fungi in the Basidiomycota. Species were formerly placed in the obsolete class Gasteromycetes Fr. (literally "stomach fungi"), or the equally obsolete order Gasteromycetales Rea, because they produce spores inside their basidiocarps (fruit bodies) rather than on an outer surface. However, the class is polyphyletic, as such species—which include puffballs, earthstars, stinkhorns, and false truffles—are not closely related to each other. Because they are often studied as a group, it has been convenient to retain the informal (non- taxonomic) name of "gasteroid fungi". History Several gasteroid fungi—such as the stinkhorn, ''Phallus impudicus'' L.—were formally described by Carl Linnaeus in his original '' Species Plantarum'' of 1753, but the first critical treatment of the group was by Christiaan Hendrik Persoon in his ''Synopsis methodica fungorum'' of 1801. Until 1981, this book was the starting point for the naming of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Receptacle (botany)
In botany, the receptacle refers to vegetative tissues near the end of reproductive stems that are situated below or encase the reproductive organs. Angiosperms In angiosperms, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow. In some accessory fruits, for example the pome and strawberry, the receptacle gives rise to the edible part of the fruit. The fruit of ''Rubus'' species is a cluster of drupelets on top of a conical receptacle. When a raspberry is picked, the receptacle separates from the fruit, but in blackberries, it remains attached to the fruit. — In the Daisy family (Compositae or Asteraceae), small individual flowers are arranged on a round or dome-like structure that is also called receptacle. Algae and bryophyta In phycology, receptacles occur at the ends of branches of algae mainly in the brown algae or Heterokontophyta in the Order Fucales. They are spec ...

Flux
Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. Flux is a concept in applied mathematics and vector calculus which has many applications to physics. For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface. Terminology The word ''flux'' comes from Latin: ''fluxus'' means "flow", and ''fluere'' is "to flow". As ''fluxion'', this term was introduced into differential calculus by Isaac Newton. The concept of heat flux was a key contribution of Joseph Fourier, in the analysis of heat transfer phenomena. His seminal treatise ''Théorie analytique de la chaleur'' (''The Analytical Theory of Heat''), defines ''fluxion'' as a central quantity and proceeds to derive the now well-known express ...

Polysaccharide
Polysaccharides (), or polycarbohydrates, are the most abundant carbohydrates found in food. They are long chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages. This carbohydrate can react with water (hydrolysis) using amylase enzymes as catalyst, which produces constituent sugars (monosaccharides, or oligosaccharides). They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch, glycogen and galactogen and structural polysaccharides such as cellulose and chitin. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more t ...
