Hygrophorus Russula
''Hygrophorus russula'', commonly known as the pinkmottle woodwax, false russula and russula-like waxy cap, is a fungus native to North America and Europe. German naturalist Jacob Christian Schäffer described the species as ''Agaricus russula'' in 1774. The species name is derived from its reddish coloration, reminiscent of members of the genus ''Russula''. French botanist Claude Casimir Gillet placed it in the genus ''Tricholoma'' in 1878, before American naturalist Calvin Henry Kauffman transferred it to ''Hygrophorus'' in 1918. Though Kauffman thought it resembled ''Tricholoma'', he held that its waxy gills showed it to be better suited to the genus ''Hygrophorus''. The fruit bodies, or mushrooms, can be abundant some years, especially after rainfall, sometimes appearing in arcs or fairy rings. The cap is hemispherical before flattening out with age, though the cap margin remains inrolled. Reaching in diameter, it has a base colour of white or pink with streaks of pink, wine ...

Jacob Christian Schäffer
Jacob Christian Schäffer, alternatively Jakob, (31 May 1718 – 5 January 1790) was a German dean, professor, botanist, mycologist, entomologist, ornithologist and inventor. Biography From 1736 to 1738 he studied Theology at the University of Halle before becoming a teacher in Ratisbon. In 1760, the University of Wittenberg gave him the title of Doctor of Philosophy, and the University of Tübingen awarded him in 1763 the title of Doctor of Divinity. In 1741, he became a pastor of a Protestant parish. In 1779, while still a pastor, he also became the dean of the Protestant parish in Ratisbon. Works In 1759, Schäffer published ''Erleichterte Artzney-Kräuterwissenschaft'', a handbook of botany and the medicinal effects of plants for doctors and pharmacists. From 1762 to 1764, he wrote four richly illustrated volumes on mycology, ''Natürlich ausgemahlten Abbildungen baierischer und pfälzischer Schwämme, welche um Regensburg wachsen''. In 1774, he wrote ''Elementa Ornitholo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or universal ve ...

Fungi Of North America
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a 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 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 organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Veil (mycology)
A veil or velum, in mycology, is one of several structures in fungi, especially the thin membrane that covers the cap and stalk of an immature mushroom. Encarta Dictionary Veils fall into two categories: * * Universal veil
In mycology, a universal veil is a temporary membranous tissue that fully envelops immature fruiting bodies of certain gilled mushrooms. The developing Caesar's mushroom (''Amanita caesarea''), for example, which may resemble a small white sphe ...

Hygrophorus Purpurascens
''Hygrophorus purpurascens'', commonly known as the veiled purple hygrophorus, is a species of agaric fungus in the family Hygrophoraceae. Its cap has a pink background color with streaks of purplish red overlaid, and mature gills have red spots. Taxonomy The species was originally described as ''Agaricus purpurascens'' by Johannes Baptista von Albertini and Lewis David de Schweinitz in 1805. Elias Fries transferred it to the genus ''Hygrophorus'' in 1838. Paul Kummer's 1871 ''Limacium purpurascens'' is a synonym. The specific epithet ''purpurascens'' means "becoming purple". It is commonly known as the "veiled purple hygrophorus". Description The cap is convex to flattened, measuring in diameter. The color is pinkish red in the center to white, often irregularly tinged with pink. The flesh is white. The gills have a decurrent attachment to the stipe and are white to pale pink spotted with pinkish or purplish red. The stipe measures long by wide, and is more or less the sa ...

Decurrent
''Decurrent'' (sometimes decurring) is a term used in botany and mycology to describe plant or fungal parts that extend downward. In botany, the term is most often applied to leaf blades that partly wrap or have wings around the stem or petiole and extend down along the stem. A "decurrent branching habit" is a plant form common for shrubs and most angiosperm trees, contrasted with the excurrent or "cone-shaped crown" common among many gymnosperms. The decurrent habit is characterized by having weak apical dominance that eventually produces a rounded or spreading tree crown. Examples of trees with decurrent habit are most hardwood trees: oak, hickory, maple, etc.Claud L. Brown, Robert G. McAlpine, Paul P. Kormanik, "Apical Dominance and Form in Woody Plants: A Reappraisal", ''American Journal of Botany'', Vol. 54, No. 2 (February 1967), pp. 153–162, In mycology, the term is most often applied to the hymenophore of a basidiocarp (such as the lamellae or "gills" of a mushroo ...

Fairy Ring
A fairy ring, also known as fairy circle, elf circle, elf ring or pixie ring, is a naturally occurring ring or arc of mushrooms. They are found mainly in forested areas, but also appear in grasslands or rangelands. Fairy rings are detectable by sporocarps (fungal spore pods) in rings or arcs, as well as by a necrotic zone (dead grass), or a ring of dark green grass. Fungus mycelium is present in the ring or arc underneath. The rings may grow to over in diameter, and they become stable over time as the fungus grows and seeks food underground. Fairy rings are the subject of much folklore and myth worldwide—particularly in Western Europe. They are often seen as hazardous or dangerous places, and linked with witches or the Devil in folklore. Conversely, they can sometimes be linked with good fortune. Genesis The mycelium of a fungus growing in the ground absorbs nutrients by secretion of enzymes from the tips of the hyphae (threads making up the mycelium). This breaks down larg ...
