Collybia Cirrhata
''Collybia cirrhata'' is a species of fungus in the family Tricholomataceae of the order Agaricales (gilled mushrooms). The species was first described in the scientific literature in 1786, but was not validly named until 1803. Found in Europe, Northern Eurasia, and North America, it is known from temperate, boreal, and alpine or arctic habitats. It is a saprobic species that grows in clusters on the decaying or blackened remains of other mushrooms. The fruit bodies are small, with whitish convex to flattened caps up to in diameter, narrow white gills, and slender whitish stems long and up to thick. ''C. cirrhata'' can be distinguished from the other two members of ''Collybia'' by the absence of a sclerotium at the base of the stem. The mushroom, although not poisonous, is considered inedible because of its insubstantial size. Taxonomy and phylogeny The species first appeared in the scientific literature in 1786 as ''Agaricus amanitae'' by August Johann Georg Karl B ...

Heinrich Christian Friedrich Schumacher
Heinrich Christian Friedrich Schumacher (15 November 1757 in Glückstadt, Holstein – 9 December 1830) was a Danish surgeon, botanist and professor of anatomy at the University of Copenhagen. Schumacher carried out significant research work in malacology, in other words on molluscs, and described several taxa. Life Early years (1757-1778) He was born to Joachim Christian Schumacher, a sergeant in the infantry of the Duchy of Schleswig, and his wife, Caroline Magdalene in Glückstadt in present-day Germany. In spite of his family's limited means, he received a good upbringing, and was sent to grammar school in Rendsburg. After confirmation became the apprentice of the regiment surgeon, Mehl, a learned and skilled man, who gave his eager student a thorough introduction to both medicine and botany, thereby waking Schumacher's natural gift for science. By 1773, at the age of 16, his keen efforts got him appointed as a military surgeon with his father's battalion in the army statione ...

Alpine Climate
Alpine climate is the typical weather (climate) for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrocollybia Racemosa
''Dendrocollybia'' is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species ''Dendrocollybia racemosa'', commonly known as the branched Collybia or the branched shanklet. The somewhat rare species is found in the Northern Hemisphere, including the Pacific Northwest region of western North America, and Europe, where it is included in several Regional Red Lists. It usually grows on the decaying fruit bodies of other agarics—such as ''Lactarius'' and ''Russula''—although the host mushrooms may be decayed to the point of being difficult to recognize. ''Dendrocollybia racemosa'' fruit bodies have small pale grayish-white or grayish-brown caps up to wide, and thin stems up to long. The species is characterized by its unusual stem, which is covered with short lateral branches. The branches often produce spherical slimeheads of translucent conidiophores on their swollen tips. The conidiophores produce conidia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clitocybe Dealbata
''Clitocybe dealbata'', also known as the ivory funnel, is a small white funnel-shaped toadstool widely found in lawns, meadows and other grassy areas in Europe and North America. Also known as the sweating mushroom, it derives this name from the symptoms of poisoning. It contains potentially deadly levels of muscarine. Taxonomy and naming ''Clitocybe dealbata'' was initially described by United Kingdom, British natural history, naturalist James Sowerby in 1799 as ''Agaricus dealbatus'', its specific epithet derived from the Late Latin verb ''dealbare'' 'to whitewash', inexorably calling to mind the Biblical "whited sepulchre", that is outwardly pleasing but inwardly toxic. It gained its current genus name in 1874 when reclassified by French naturalist Claude Casimir Gillet. However, this species is often considered a synonym of ''Clitocybe rivulosa'' and according to Bon the name ''C. dealbata'' may be invalid (a :w:en:Nomen dubium, nomen dubium) as James Sowerby's defini ...

Collybia Cookei
''Collybia cookei'' is a species of fungus in the family Tricholomataceae, and one of three species in the genus ''Collybia''. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like ''Meripilus giganteus'', ''Inonotus hispidus'', or species of ''Russula''; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of ''Collybia'' unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined. Taxonomy and phylogeny The species was first described in the scientific literature in 1928 as ''Collybia cirrhata'' var. ''cookei'' by the Italian mycologist Giacomo Bresadola. In a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collybia Tuberosa
''Collybia tuberosa'', commonly known as the lentil shanklet or the appleseed coincap, is an inedible species of fungus in the family Tricholomataceae, and the type species of the genus ''Collybia''. Like the two other members of its genus, it lives on the decomposing remains of other fleshy mushrooms. The fungus produces small whitish fruit bodies with caps up to wide held by thin stems up to long. On the underside of the cap are closely spaced white gills that are broadly attached to the stem. At the base of the stem, embedded in the substrate is a small reddish-brown sclerotium that somewhat resembles an apple seed. The appearance of the sclerotium distinguishes it from the other two species of ''Collybia'', which are otherwise very similar in overall appearance. ''C. tuberosa'' is found in Europe, North America, and Japan, growing in dense clusters on species of ''Lactarius'' and ''Russula'', boletes, hydnums, and polypores. Taxonomy, phylogeny, and naming The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poisonous Mushroom
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxic substances. Its symptoms can vary from slight gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus. Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a toxic mushroom as an edible species. The most common reason for this misidentification is a close resemblance in terms of color and general morphology of the toxic mushrooms species with edible species. To prevent mushroom poisoning, mushroom gatherers familiarize themselves with the mushrooms they intend to collect, as well as with any similar-looking toxic species. The safety of eating wild mushrooms may depend on methods of preparation for cooking. Signs and symptoms Poisonous mushrooms contain a variety of different toxins that can differ markedly in toxicity. Symptoms of mushroom poisoning may vary from gastric upset ...

Sclerotium
A sclerotium (; (), is a compact mass of hardened fungal mycelium containing food reserves. One role of sclerotia is to survive environmental extremes. In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return. Sclerotia initially were mistaken for individual organisms and described as separate species until Louis René Tulasne proved in 1853 that sclerotia are only a stage in the life cycle of some fungi. Further investigation showed that this stage appears in many fungi belonging to many diverse groups. Sclerotia are important in the understanding of the life cycle and reproduction of fungi, as a food source, as medicine (for example, ergotamine), and in agricultural blight management. Examples of fungi that form sclerotia are ergot (''Claviceps purpurea''), ''Polyporus tuberaster'', ''Psilocybe mexicana'', ''Sclerotium delphinii'' and many species in Sclerotiniaceae. Although not fungal, the plasmodium of slime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collybia
''Collybia'' (in the strict sense) is a genus of mushrooms in the family Tricholomataceae. The genus has a widespread but rare distribution in northern temperate areas, and contains three species that grow on the decomposing remains of other mushrooms. Until recently a large number of other white-spored species, some very common, were assigned to this genus, but now the majority have been separated into other genera: ''Gymnopus'', '' Rhodocollybia'' and '' Dendrocollybia''. ''Collybia'' sensu lato ''Collybia'' sensu lato is one of the groups of fungi of the order Agaricales that has created taxonomic differences of opinion in the scientific community. The generic name ''Collybia'' is due to Elias Magnus Fries and first appeared in 1821. ''Collybia'' was originally a tribe from an Agaricus classification. In 1857, Friedrich Staude recognized ''Collybia'' as a genus. The name ''Collybia'' means "small coin". Later in his systematic work of 1838, Fries characterized ''Collybia' ...

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 ...

Lamella (mycology)
In mycology, a lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, ''Lactarius'' species typically seep latex from their gills. It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills is that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pileus (mycology)
The pileus is the technical name for 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. 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, such as the parasol mushroom, have distinct bosses or umbos and are described as ''umbonate''. An umbo is a knobby protrusion at the center of th ...
