Psilocybe Aztecorum
''Psilocybe aztecorum'' is a species of psilocybin mushroom in the family Hymenogastraceae. Known from Arizona, Colorado, central Mexico, India and Costa Rica, the fungus grows on decomposing woody debris and is found in mountainous areas at elevations of , typically in meadows or open, grassy conifer forests. The mushrooms have convex to bell-shaped caps in diameter, atop slender cylindrical stems that are up to long. The color of the caps changes with variations in hydration, ranging from dark chestnut brown to straw yellow or whitish when dry. The base of the stem is densely covered with conspicuous white rhizomorphs, a characteristic uncommon amongst ''Psilocybe'' species. The species was first reported by French mycologist Roger Heim in 1956 as a variety of ''Psilocybe mexicana'' before he officially described it under its current name a year later. Named for its association with the Nahua people also called Aztecs, ''P. aztecorum'' may have been one of the sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevado De Toluca
Nevado de Toluca () is a stratovolcano in central Mexico, located about west of Mexico City near the city of Toluca. It is the fourth highest of Mexico's peaks, after Pico de Orizaba, Popocatépetl and Iztaccíhuatl. The volcano and the area around it is now a national park. Etymology It is often called by the Nahuatl name Xinantecatl which is usually translated as The Naked Lord, ''Señor Desnudo'' in Spanish, although other etymologies have been suggested such as "Lord of the Corn Stalks", Tzinacantecatl or Zinacantepetl (Mountain of the Bats). Further evidence regarding the etymologies of this mountain has surfaced after many archeology discoveries in and around the area. It has been concluded that its correct etymology is Chicnauhtecatl meaning "Lord of Nine", probably referring to the various deep lakes at the top of the cone. Description The volcano has a wide summit caldera which is open to the east. The highest summit, the Pico del Fraile (Friar's Peak), is on ...

Aztec Codices
Aztec codices ( nah, Mēxihcatl āmoxtli , sing. ''codex'') are Mesoamerican manuscripts made by the pre-Columbian Aztec, and their Nahuatl-speaking descendants during the colonial period in Mexico. History Before the start of the Spanish colonization of the Americas, the Mexica and their neighbors in and around the Valley of Mexico relied on painted books and records to document many aspects of their lives. Painted manuscripts contained information about their history, science, land tenure, tribute, and sacred rituals. According to the testimony of Bernal Díaz del Castillo, Moctezuma had a library full of such books, known as ''amatl'', or ''amoxtli,'' kept by a ''calpixqui'' or nobleman in his palace, some of them dealing with tribute. After the conquest of Tenochtitlan, indigenous nations continued to produce painted manuscripts, and the Spaniards came to accept and rely on them as valid and potentially important records. The native tradition of pictorial document ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life (magazine)
''Life'' was an American magazine published weekly from 1883 to 1972, as an intermittent "special" until 1978, and as a monthly from 1978 until 2000. During its golden age from 1936 to 1972, ''Life'' was a wide-ranging weekly general-interest magazine known for the quality of its photography, and was one of the most popular magazines in the nation, regularly reaching one-quarter of the population. ''Life'' was independently published for its first 53 years until 1936 as a general-interest and light entertainment magazine, heavy on illustrations, jokes, and social commentary. It featured some of the most notable writers, editors, illustrators and cartoonists of its time: Charles Dana Gibson, Norman Rockwell and Jacob Hartman Jr. Gibson became the editor and owner of the magazine after John Ames Mitchell died in 1918. During its later years, the magazine offered brief capsule reviews (similar to those in ''The New Yorker'') of plays and movies currently running in New York City, bu ...

Paso De Cortés
The Paso de Cortés is the mountain pass or saddle between the Popocatépetl and Ixtaccíhuatl volcanoes in central Mexico. It is part of the Trans-Mexican Volcanic Belt, where the normally southeast-trending continental divide turns north for over . The altitude of the pass is about . It is located in the municipality of Amecameca in the State of México. History The name derives from the transit of conquistador Hernán Cortés and his men over the pass in 1519. After the battle of Cholula, the Spanish continued northwest into the Valley of Mexico and the city of Tenochtitlán to confront the Aztecs and their emperor Moctezuma. It is claimed that while crossing the pass, some of Cortés' men climbed Popocatépetl, lowered into the crater, and brought back sulphur for making gunpowder. Access There is a paved road from Amecameca on the Mexico City Mexico City ( es, link=no, Ciudad de México, ; abbr.: CDMX; Nahuatl: ''Altepetl Mexico'') is the capital and largest city of Me ...

Ethnomycologist
Ethnomycology is the study of the historical uses and sociological impact of fungi and can be considered a subfield of ethnobotany or ethnobiology. Although in theory the term includes fungi used for such purposes as tinder, medicine (medicinal mushrooms) and food (including yeast), it is often used in the context of the study of psychoactive mushrooms such as psilocybin mushrooms, the '' Amanita muscaria'' mushroom, and the ergot fungus. American banker Robert Gordon Wasson pioneered interest in this field of study in the late 1950s, when he and his wife became the first Westerners on record allowed to participate in a mushroom ''velada'', held by the Mazatec '' curandera'' María Sabina. The biologist Richard Evans Schultes is also considered an ethnomycological pioneer. Later researchers in the field include Terence McKenna, Albert Hofmann, Ralph Metzner, Carl Ruck, Blaise Daniel Staples, Giorgio Samorini, Keewaydinoquay Peschel, John Marco Allegro, Clark Heinrich, John W.

Cystidia
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] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Sacred Fir
''Abies religiosa'', the oyamel fir or sacred fir, (known as in Spanish) is a fir native to the mountains of central and southern Mexico ( Trans-Mexican Volcanic Belt, Sierra Madre del Sur) and western Guatemala. It grows at high altitudes of in cloud forests with cool, humid summers and dry winters in most of its habitat regime. In the state of Veracruz, it grows with precipitation all year long. The tree is resistant to regular winter snowfalls. Names The Spanish name comes from the Nahuatl word ''oyametl'' (''oya'', "to thresh"; ''metl'', " agave"; literally "threshing agave"). It is also called (Christmas tree) in Mexico. The English name derives from the binomial ''Abies religiosa'', literally "religious fir". This comes from the use of its cut foliage in religious festivals (notably at Christmas) and in churches in Mexico. Description ''Abies religiosa'' is a medium-sized to large evergreen coniferous tree growing to tall with a trunk diameter of up to . The lea ...
