Truffles
A truffle is the fruiting body of a subterranean ascomycete fungus, predominantly one of the many species of the genus ''Tuber''. In addition to ''Tuber'', many other genera of fungi are classified as truffles including ''Geopora'', ''Peziza'', ''Choiromyces'', ''Leucangium'', and over a hundred others. These genera belong to the class Pezizomycetes and the Pezizales order. Several truffle-like basidiomycetes are excluded from Pezizales, including ''Rhizopogon'' and ''Glomus''. Truffles are ectomycorrhizal fungi, so they are usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi. These fungi have significant ecological roles in nutrient cycling and drought tolerance. Some truffle species are highly prized as food. French gastronome Jean Anthelme Brillat-Savarin called truffles "the diamond of the kitchen". Edible truffles are used in Italian, French and numerous other national . Truffles are cultivated ...

Tuber Melanosporum
''Tuber melanosporum'', called the black truffle, Périgord truffle or French black truffle, is a species of truffle native to Southern Europe. It is one of the most expensive edible mushrooms in the world. Taxonomy Italian naturalist Carlo Vittadini described the black truffle in 1831. Description External characteristics The round, dark brown fruiting bodies (ascocarps) have a black-brown skin with small pyramidal cusps. They have a strong, aromatic smell and normally reach a size of up to . Some may be significantly larger, such as a black truffle found in 2012 in Dordogne with a mass of . Their flesh is initially white, then dark. It is permeated by white veins, which turn brown with age. The spores are elliptical and measure about 22–55 µm by 20–35 µm. They are dark brown and covered with large spikes. Aroma The fruiting bodies of the black truffle exude a scent reminiscent of undergrowth, strawberries, wet earth, or dried fruit with a hint of cocoa. ...

Fungiculture
Fungiculture is the cultivation of fungi such as mushrooms. Cultivating fungi can yield foods (which include mostly mushrooms), medicine, construction materials and other products. A ''mushroom farm'' is involved in the business of growing fungi. The word is also commonly used to refer to the practice of cultivation of fungi by animals such as leafcutter ants, termites, ambrosia beetles, and marsh periwinkles. Overview Mushrooms are not plants, and require different conditions for optimal growth. Plants develop through photosynthesis, a process that converts atmospheric carbon dioxide into carbohydrates, especially cellulose. While sunlight provides an energy source for plants, mushrooms derive all of their energy and growth materials from their growth medium, through biochemical decomposition processes. This does not mean that light is an irrelevant requirement, since some fungi use light as a signal for fruiting. However, all the materials for growth must already be pre ...

Rhizopogon
''Rhizopogon'' is a genus of ectomycorrhizal basidiomycetes in the family Rhizopogonaceae. Species form hypogeous sporocarps commonly referred to as "false truffles". The general morphological characters of ''Rhizopogon'' sporocarps are a simplex or duplex peridium surrounding a loculate gleba that lacks a columnella. Basidiospores are produced upon basidia that are borne within the fungal hymenium that coats the interior surface of gleba locules. The peridium is often adorned with thick mycelial cords, also known as rhizomorphs, that attach the sporocarp to the surrounding substrate. The scientific name ''Rhizopogon'' is Greek for 'root' (Rhiz-) 'beard' (-pogon) and this name was given in reference to the rhizomorphs found on sporocarps of many species. ''Rhizopogon'' species are primarily found in ectomycorrhizal association with trees in the family Pinaceae and are especially common symbionts of pine, fir, and Douglas fir trees. Through their ectomycorrhizal relationshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycete
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomycetes ...

Geopora
''Geopora'' is a genus of truffle-like fungi in the family Pyronemataceae, currently with 13 described species. The genus was circumscribed by mycologist Harvey Willson Harkness in 1885. Molecular phylogenetic reconstructions indicate that the cup-like apothecial ''Geopora'' should better be placed back in a separate genus, ''Sepultaria''. ''Geopora'' would then only comprise ''Geopora cooperi'' and its close relatives. Species Species include: * '' Geopora arenicola'' * ''Geopora arenosa'' * ''Geopora cercocarpi'' * ''Geopora cervina'' * ''Geopora cooperi'' * ''Geopora foliacea'' * ''Geopora sepulta'' * '' Geopora sumneriana'' * ''Geopora tenuis ''Geopora'' is a genus of truffle-like fungi in the family Pyronemataceae, currently with 13 described species.

French Cuisine
French cuisine () is the cooking traditions and practices from France. It has been influenced over the centuries by the many surrounding cultures of Spain, Italy, Switzerland, Germany and Belgium, in addition to the food traditions of the regions and colonies of France. In the 14th century, Guillaume Tirel, a court chef known as "Taillevent", wrote ''Le Viandier'', one of the earliest recipe collections of medieval France. In the 17th century, chefs François Pierre La Varenne and Marie-Antoine Carême spearheaded movements that shifted French cooking away from its foreign influences and developed France's own indigenous style. Cheese and wine are a major part of the cuisine. They play different roles regionally and nationally, with many variations and ''appellation d'origine contrôlée'' (AOC) (regulated appellation) laws. Culinary tourism and the ''Guide Michelin'' helped to acquaint commoners with the ''cuisine bourgeoise'' of the urban elites and the peasant cuisine o ...

Ectomycorrhiza
An ectomycorrhiza (from Greek ἐκτός ', "outside", μύκης ', "fungus", and ῥίζα ', "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their host's cell walls. Instead they form an entirely intercellular interface known as the Hartig net, consisting of highly branched hyphae form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amorite
The Amorites (; sux, 𒈥𒌅, MAR.TU; Akkadian: 𒀀𒈬𒊒𒌝 or 𒋾𒀉𒉡𒌝/𒊎 ; he, אֱמוֹרִי, 'Ĕmōrī; grc, Ἀμορραῖοι) were an ancient Northwest Semitic-speaking people from the Levant who also occupied large parts of southern Mesopotamia from the 21st century BC to the end of the 17th century BC, where they established several prominent city-states in existing locations, such as Isin, Larsa and later notably Babylon, which was raised from a small town to an independent state and a major city. The term in Akkadian and Sumerian texts refers to the Amorites, their principal deity and an Amorite kingdom. The Amorites are also mentioned in the Bible as inhabitants of Canaan both before and after the conquest of the land under Joshua. Origin In the earliest Sumerian sources concerning the Amorites, beginning about 2400 BC, the land of the Amorites ("the ''Mar.tu'' land") is associated not with Mesopotamia but with the lands to the west o ...

Third Dynasty Of Ur
The Third Dynasty of Ur, also called the Neo-Sumerian Empire, refers to a 22nd to 21st century Common Era, BC (middle chronology) Sumerian ruling dynasty based in the city of Ur and a short-lived territorial-political state which some historians consider to have been a nascent empire. The Third Dynasty of Ur is commonly abbreviated as Ur III by historians studying the period. It is numbered in reference to previous dynasties, such as the First Dynasty of Ur (26-25th century BC), but it seems the once supposed Second Dynasty of Ur was never recorded. The Third Dynasty of Ur was the last Sumerian dynasty which came to preeminent power in Mesopotamia. It began after several centuries of control by Akkadian Empire, Akkadian and Gutian dynasty of Sumer, Gutian kings. It controlled the cities of Isin, Larsa, and Eshnunna and extended as far north as Upper Mesopotamia. History The Third Dynasty of Ur arose some time after the fall of the Akkadian Empire, Akkad Dynasty. The period betwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theophrastus
Theophrastus (; grc-gre, Θεόφραστος ; c. 371c. 287 BC), a Greek philosopher and the successor to Aristotle in the Peripatetic school. He was a native of Eresos in Lesbos.Gavin Hardy and Laurence Totelin, ''Ancient Botany'', Routledge, 2015, p. 8. His given name was Tyrtamus (); his nickname (or 'godly phrased') was given by Aristotle, his teacher, for his "divine style of expression". He came to Athens at a young age and initially studied in Plato's school. After Plato's death, he attached himself to Aristotle who took to Theophrastus in his writings. When Aristotle fled Athens, Theophrastus took over as head of the Lyceum. Theophrastus presided over the Peripatetic school for thirty-six years, during which time the school flourished greatly. He is often considered the father of botany for his works on plants. After his death, the Athenians honoured him with a public funeral. His successor as head of the school was Strato of Lampsacus.
