Psilocybe Aucklandiae
''Psilocybe aucklandiae'' is a species of agaric fungus in the family Hymenogastraceae known from the Auckland Region of New Zealand, where it grows from clay soils in exotic pine plantations and native forests.Johnston P, Buchanan PK. The genus Psilocybe (Agaricales) in New Zealand. ''New Zealand Journal of Botany'' 1995;33(3):379-388. It is phylogenetically similar to or almost the same as '' Psilocybe zapotecorum'' from Mexico and South America. As a blueing member of the genus ''Psilocybe'' it contains the psychoactive compounds psilocin and psilocybin. Taxonomy ''Psilocybe aucklandiae'' was officially described in 1991 by Gastón Guzmán, Chris King and Victor Bandala in 'A new species of ''Psilocybe'' of section ''Zapotecorum'' from New Zealand.' The name is feminine; the original orthography is ''aucklandii'' which has a masculine suffix. The holotype is in New Zealand with accessioPDD 57236and was collected in the Waitakere Ranges while the isotype is in XAL, Mex ...

Gastón Guzmán
Gastón Guzmán Huerta (August 26, 1932 – January 12, 2016), a Mexican mycologist and anthropologist, was an authority on the genus ''Psilocybe''. Career He was born in Xalapa, Veracruz, in 1932. His interest in mycology began in 1955 when as a graduate student he decided to update his school's (National Polytechnic Institute) poorly kept collection of fungi. During his early field work he found a large assortment of species about which little was known at the time. This inspired him to choose fungi as the topic of his professional thesis. In 1957 Guzmán was invited by the University of Mexico to assist Rolf Singer, who would arrive to Mexico the following year to study the hallucinogenic mushroom genus ''Psilocybe''. Guzmán accepted and assisted Singer through his explorations in Mexico. While they were in the Huautla de Jiménez region, in their last day of the expeditions, they met R. Gordon Wasson. For Guzmán it was a "fructiferous meeting." In 1958, he published his ... [...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 ...

Riverhead, New Zealand
Riverhead is a small, historically predominantly working-class town located at the head of the Waitematā Harbour in the north-west of Auckland, New Zealand. The region around Riverhead and the neighbouring towns of Kumeu and Huapai is known for its vineyards. This town has had its 15 minutes in the spotlight appearing in movies '' Bridge to Teribithia'' and ''Crooked Earth'' and the odd television show such as '' Outrageous Fortune''. The region features a pine plantation forest that is popular with horse riders, mountain bikers and motorcyclists. Riverhead Forest is operated by Matariki Forests, under Crown Licence. The forest was originally planted on poor kauri gum fields. History The area is traditionally a part of rohe of the tribe Te Kawerau ā Maki, who referred to the wider area was known as Rangitōpuni. The name commemorates a day of peace-making between Te Kawerau ā Maki and other tribes in the early 19th century, and refers to the act of gifting dog-skin cloaks (t ...

Pleurocystidia
A cystidium (plural cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom 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 of cystidia 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 on the stipe (caulocystidia). Especially the pleurocystidia and cheilocystidia are important for identification within many genera. Sometimes the cheilocystidia give the gill edge a distinct colour which is visible to the naked eye or wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Basidium
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multicel ...

Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...

It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it ...

Pruinescence
Pruinescence , or pruinosity, is a "frosted" or dusty-looking coating on top of a surface. It may also be called a pruina (plural: ''pruinae''), from the Latin word for hoarfrost. The adjectival form is pruinose . Entomology In insects, a "bloom" caused by wax particles on top of an insect's cuticle covers up the underlying coloration, giving a dusty or frosted appearance. The pruinescence is commonly white to pale blue in color but can be gray, pink, purple, or red; these colors may be produced by Tyndall scattering of light. When pale in color, pruinescence often strongly reflects ultraviolet. Pruinescence is found in many species of Odonata, particularly damselflies of the families Lestidae and Coenagrionidae, where it occurs on the wings and body. Among true dragonflies it is most common on male Libellulidae (skimmers). In the common whitetail and blue dasher dragonflies (''Plathemis lydia'' and ''Pachydiplax longipennis''), males display the pruinescence on the back of th ...

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 ...

Hygrophanous
The adjective hygrophanous refers to the color change of mushroom tissue (especially the pileus surface) as it loses or absorbs water, which causes the pileipellis to become more transparent when wet and opaque when dry. When identifying hygrophanous species, one needs to be careful when matching colors to photographs or descriptions, as color can change dramatically soon after picking. Genera that are characterized by hygrophanous species include ''Agrocybe'', ''Psathyrella'', ''Psilocybe'', ''Panaeolus'', and ''Galerina''.
