Pluteus Variabilicolor
''Pluteus'' is a large genus of fungi with over 300 species. They are wood rotting saprobes with pink spore prints and gills that are free from the stem. The Latin word ''Pluteus'' means ''shed or penthouse''. Characteristics of the genus Characteristics of the ''Pluteus'' genus are: #These fungi grow on wood or wood remains. #The spore powder is deep pink, soon giving a pink tint to the initially pale gills. #The gills are free from the stipe. #There is no volva or ring (exception: the rare recently reclassified North American species ''P. mammillatus'', previously ''Chamaeota sphaerospora''). #Microscopically, they often have abundant, distinctive cystidia. The spores are smooth and roughly egg-shaped. ''Pluteus'' is separated from ''Volvariella'' due to the lack of a volva, and from ''Entoloma'' by growing on wood and by microscopic features (''Entolomas'' have angular spores). Naming The name ''Pluteus'' was established in 1837 by the founding mycologist Elias Magnu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluteus Cervinus
''Pluteus cervinus'', commonly known as the deer shield, deer mushroom, or fawn mushroom, is a species of fungus in the order Agaricales. Fruit bodies are agaricoid (mushroom-shaped). ''Pluteus cervinus'' is saprotrophic and fruit bodies are found on rotten logs, roots, tree stumps, sawdust, and other wood waste. It is common in Europe and eastern North America. Etymology The species epithet, ''cervinus'', means "deer-like"" and refers to the colour of the cap (described as "rehfarbig" in Jacob Christian Schäffer's original 1774 description). Description The Pileus (mycology), cap typically grows up to in diameter. Initially it is bell-shaped and often wrinkled when young. Later it expands to a convex shape. The cap can be deer-brown, but varies from light ochre-brown to dark brown, with a variable admixture of grey or black. The centre of the cap may be darker. The cap surface is smooth and matt to silky-reflective. The cap skin shows dark radial fibres when seen through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saprobic
Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (e.g. '' Mucor'') and with soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes. - "The word saprophyte and its derivatives, implying that a fungus is a plant, can be replaced by saprobe (σαπρός + βίος), which is without such implication." Saprotrophic plants or bacterial flora are called saprophytes ( ''sapro-'' 'rotten material' + ''-phyte'' 'plant'), although it is now believed that all plants previously thought to be saprotrophic are in fact parasites of microscopic fungi or of other plants. In fungi, the saprotrophic process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae. states the purpose of sa ...

List Of Pluteus Species
This is an incomplete list of species in the agaric genus ''Pluteus''. Species of ''Pluteus'' are commonly found growing on woody substrates including stumps, logs, fallen branches, woody debris such as sawdust, and buried wood. Three sections are widely accepted in ''Pluteus'', including ''Pluteus'', ''Hispidoderma'' Fayod, and ''Celluloderma'' Fayod. Section ''Pluteus'' is characterized by fruit bodies with a filamentous cap cuticle The pileipellis is the uppermost layer of hyphae in the pileus of a fungal fruit body. It covers the trama, the fleshy tissue of the fruit body. The pileipellis is more or less synonymous with the cuticle, but the cuticle generally describes th ...

Pluteus Phaeocyanopus
''Pluteus phaeocyanopus'' is an agaric fungus in the family Pluteaceae. Described as a new species in 2010, it has only been collected from California, where it grows singularly or in groups on the decaying wood of oak. The fruit body has a smooth brown cap measuring in diameter. The stipe is long by thick, and roughly equal in width throughout. It is whitish but becomes grayish-green near the base. The thin and fragile gills are free from attachment to the stipe, close to somewhat distantly placed, and interspersed with several tiers of lamellulae (short gills). The flesh has no distinctive taste or odor. The spores are spherical or nearly so and measure 6.2–8.4 by 5.7–7.9 μm. The species was originally collected from San Francisco (California) in 1966 by American mycologist Harry D. Thiers and assigned to ''Pluteus cyanopus ''Pluteus cyanopus'' is a species of agaric fungus in the family Pluteaceae. Found in Africa, Europe, and North America, its fruit bodies c ...

Psilocybin
Psilocybin, also known as 4-phosphoryloxy-''N'',''N''-dimethyltryptamine (4-PO-DMT), is a natural product, naturally occurring tryptamine alkaloid and Investigational New Drug, investigational drug found in more than List of psilocybin mushroom species, 200 species of mushrooms, with Hallucinogen, hallucinogenic and Serotonin, serotonergic effects. Effects include euphoria, changes in perception, a distorted sense of time (via brain desynchronization), and perceived spiritual experiences. It can also cause adverse reactions such as nausea and panic attacks. Its effects depend on set and setting and one's subject-expectancy effect, expectations. Psilocybin is a prodrug of psilocin. That is, the compound itself is biologically inactive but quickly converted by the body to psilocin. Psilocybin is transformed into psilocin by dephosphorylation mediated via phosphatase enzymes. Psilocin is structural analog, chemically related to the neurotransmitter serotonin and acts as a binding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entoloma
''Entoloma'' is a genus of fungi in the order Agaricales. Called pinkgills in English, basidiocarps (fruit bodies) are typically agaricoid (gilled mushrooms), though a minority are gasteroid. All have salmon-pink basidiospores which colour the gills at maturity and are angular ( polyhedral) under a microscope. The genus is large, with almost 2000 species worldwide. Most species are saprotrophic, but some are ectomycorrhizal, and a few are parasitic on other fungi. The type, ''Entoloma sinuatum'', is one of several ''Entoloma'' species that are poisonous, typically causing mild to severe gastrointestinal illness. Taxonomy History In 1838 the Swedish mycologist Elias Magnus Fries classified all pink-spored, gilled fungi into "tribes" or "subtribes", placing those with a '' Tricholoma''-like shape and gills attached to the stem into tribe ''Entoloma''. The small subtribe ''Leptonia'' had convex fleshy membranaceous caps, the subtribe ''Nolanea'' were slender fungi with bell-sha ...

Volva (mycology)
In mycology, a volva is a cup-like structure at the base of a mushroom that is a remnant of the universal veil, or the remains of the peridium that encloses the immature fruit bodies of gasteroid fungi. This macrofeature is important in wild mushroom identification because it is an easily observed, taxonomically significant feature that frequently signifies a member of Amanitaceae. This has particular importance due to the disproportionately high number of deadly poisonous species contained within that family. A mushroom's volva is often partially or completely buried in the ground, and therefore care must be taken to check for its presence when identifying mushrooms. Cutting or pulling mushrooms and attempting to identify them later without having noted this feature could be a fatal error. Whilst a volva is a feature best known from ''Amanita'' species and stinkhorns such as the Phallaceae family and others in the Phallales order, it may also occur with other genera in ...

Volvariella
''Volvariella'' is a genus of fungi with deep salmon-pink gills and spore prints. Description The mushrooms lack a ring, and have an Amanita-like volva at the stem base. Some species of ''Amanita'' look similar, but ''Amanita'' has white spores and often have a ring. Since the gills of young ''Volvariella'' are white at first, they are more easily mistaken for ''Amanita''. The genus is estimated to contain about 50 species. Taxonomy Many sources list ''Volvariella'' as a member of the Pluteaceae family, but recent DNA studies have revealed that '' Pluteus'' and ''Volvariella'' evolved separately and have very different DNA. These studies show that ''Volvariella'' is very closely related to "schizophylloid" mushrooms like '' Schizophyllum commune''. Species Uses '' Volvariella volvacea'', well known as the "paddy straw mushroom", is cultured in rice straw in the Philippines and Southeast Asia. This species also favors wood chip piles. It is easy to confuse with ''Amanita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cystidium
A cystidium (: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom A mushroom or toadstool is the fleshy, spore-bearing Sporocarp (fungi), fruiting body of a fungus, typically produced above ground on soil or another food source. ''Toadstool'' generally refers to a poisonous mushroom. The standard for the n ... gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in the identification of basidiomycetes. In general, the adaptive significance of cystidia is not well understood. Classification By position Cystidia may occur on the edge of a lamella (or analogous hymenophoral structure) (cheilocystidia), on the face of a lamella (pleurocystidia), on the surface of the cap (dermatocystidia or pileocystidia), on the margin of the cap (circumcystidia) or o ...

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 (ring) or cortina) or ...

Lamella (mycology)
In mycology, a lamella (: lamellae), 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 evolv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
