Psilocybe Hispanica
''Psilocybe hispanica'' is a species of fungus in the family Hymenogastraceae. It produces small brown mushrooms with conical to convex caps up to in diameter and stems long by thick. Reported as new to science in 2000, it is only known from the Pyrenees mountain range in northern Spain and southwestern France, where it grows on horse dung in grass fields at elevations of . The mushroom contains the psychoactive compound psilocybin. The possible depiction of this species in the 6,000-year-old Selva Pascuala rock art suggests that it might have been used in ancient religious rituals—the oldest evidence of such usage in prehistoric Europe. Taxonomy The species was described by Mexican mycologist Gastón Guzmán in a 2000 publication, based on specimens collected by Ignacio Seral Bozal near Huesca in northern Spain in 1995. ''Psilocybe hispanica'' is classified in the section ''Semilanceata'' of the genus ''Psilocybe'' because of its thick-walled spores and fruit body that br ...

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] |
Basidiocarp
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye (especially those with a more or less agaricoid morphology) are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles. Structure All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi. In more complex basidiocarps, there is differentiation into a stipe, a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidia
A basidium (: basidia) is a microscopic spore-producing structure found on the hymenophore of reproductive bodies of basidiomycete fungi. The presence of basidia is one of the main characteristic features of the group. These bodies are also called tertiary mycelia, which are highly coiled versions of secondary mycelia. A basidium usually bears four sexual spores called basidiospores. Occasionally the number may be two or even eight. Each reproductive spore is produced at the tip of a narrow prong or horn called a sterigma (), and is forcefully expelled at full growth. The word ''basidium'' literally means "little pedestal". This is the way the basidium supports the spores. However, some biologists suggest that the structure looks more like a club. A partially grown basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but some have ones with many cells (a phragmobasidia). For instance, rust fungi in the order ''Puccinal ...

Sterigma
In biology, a sterigma (: sterigmata) is a small supporting structure. It commonly refers to an extension of the basidium (the spore-bearing cells) consisting of a basal filamentous part and a slender projection which carries a spore at the tip. The sterigmata are formed on the basidium as it develops and undergoes meiosis, to result in the production of (typically) four nuclei. The nuclei gradually migrate to the tips of the basidium, and one nucleus will migrate into each spore that develops at the tip of each sterigma. In less common usage, a sterigma is a structure within the posterior end of the genitalia of female Lepidoptera. It also refers to the stem-like structure, also called a "woody peg" at the base of the leaves of some, but not all conifers, specifically ''Picea'' and ''Tsuga ''Tsuga'' (, from Japanese (), the name of '' Tsuga sieboldii'') is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family.

Hilum (biology)
In botany, a hilum (pronounced ) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). On a bean seed, the hilum is called the "eye". For some species of fungus, the hilum is the microscopic indentation left on a spore when it separates from the sterigma of the basidium. A hilum can also be a nucleus of a starch grain; the point around which layers of starch are deposited. The adjectival form ''hilar'' denotes the presence of such a mark, and can be used as a distinguishing characteristic of a seed or spore In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions.

Germ Pore
A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be wikt:apical, apical or eccentric in its location, and, on light microscopy, may be visualized as a lighter coloured area on the cell wall. Apical germ pore is mushroom spore which has a pore at one end. Some spores have a hole in the cell wall where the first strand of germinating mycelium emerges. If the cell wall is divided from one end to the other, this is called a germ slit. Commonly the germ pore is at one end of the mushroom spore and is called an apical pore. Mushroom genera with apical germ pores include ''Agrocybe'', ''Panaeolus'', ''Psilocybe'', and ''Pholiota''.

Micrometre
The micrometre (English in the Commonwealth of Nations, Commonwealth English as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI Unit, SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cell (biology), cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of str ...

Ellipsoid
An ellipsoid is a surface that can be obtained from a sphere by deforming it by means of directional Scaling (geometry), scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a Surface (mathematics), surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar Cross section (geometry), cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is Bounded set, bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular Rotational symmetry, axes of symmetry which intersect at a Central symmetry, center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal ax ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trama (mycology)
In mycology, the term trama is used in two ways. In the broad sense, it is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue that is commonly referred to as the "flesh" of mushrooms and similar fungi.Largent D, Johnson D, Watling R. 1977. ''How to Identify Mushrooms to Genus III: Microscopic Features''. Arcata, CA: Mad River Press. . pp. 60–70. The second use is more specific, and refers to the "hymenophoral trama" that supports the hymenium. It is similarly interior, connective tissue, but it is more specifically the central layer of hyphae running from the underside of the mushroom cap to the lamella or gill, upon which the hymenium rests. Various types have been classified by their structure, including trametoid, cantharelloid, boletoid, and agaricoid, with agaricoid the m ...

Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the Stipe (mycology), stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gill (mushroom), gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species Species description, descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guides and on identification websites. Ring descriptions The way in which the structure and appearance of rings is described can vary with author and the description may only note the existence of a ring without providing specific information in cases where the ring lacks any notable features that ...

Wine (color)
The color wine, or wine red (also called bordeaux, vinous, or vinaceous), is a dark shade of red. It is a representation of the typical color of red wine. The first recorded use of ''wine'' as a color name in English was in 1705. The word ''bordeaux'' is also sometimes used to describe this color. Variations of the color term Claret The color claret is displayed adjacent. Claret is a representation of the average color of Bordeaux wine. Accordingly, another name for this color is Bordeaux. Bordeaux however is more widely used as a color name in European languages other than English, where ''claret'' has had longer history. The first recorded use of ''claret'' as a color name in English was in 1547. Burgundy Burgundy is a red color associated with the Burgundy wine of the same name, which in turn is named after the Burgundy region of France. The first recorded use of "burgundy" as a color name in English was in 1881. Wine dregs Wine dregs, or dregs of wine, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
