Truffle
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 cultivat ...

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. ...

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 ...

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 ...

Leucangium
''Leucangium'' is a genus of ascomycete fungi. The genus was circumscribed by French mycologist Lucien Quélet in 1883. Although classified in the Helvellaceae in the past (''e.g.'', in ''Dictionary of the Fungi'', 10th edition, 2008), molecular analysis indicates it is closely related to the genus ''Fischerula'' and ''Imaia'', and therefore must be placed in the Morchellaceae. The genus includes two species, ''Leucangium ophthalmosporum'' Quél. (the type of the genus) and '' L. carthusianum'' (Tul. & C. Tul.) Paol., and both of them produce sequestrate (fully or partly underground) ascoma, globose to ellipsoidal ascus (inamyloid and eight-spored), and dark olive-colored to grayish green, smooth, fusiform ascospore An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or s ...s. Refer ...

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] |
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] |
Pezizales
The Pezizales are an order of the subphylum Pezizomycotina within the phylum Ascomycota. The order contains 16 families, 199 genera, and 1683 species. It contains a number of species of economic importance, such as morels, the black and white truffles, and the desert truffles. The Pezizales can be saprobic, mycorrhizal, or parasitic on plants. Species grow on soil, wood, leaves and dung. Soil-inhabiting species often fruit in habitats with a high pH and low content of organic matter, including disturbed ground. Most species occur in temperate regions or at high elevation. Several members of the Sarcoscyphaceae and Sarcosomataceae are common in tropical regions. Description Members of this order are characterized by asci that typically open by rupturing to form a terminal or eccentric lid or operculum. The ascomata are apothecia or are closed structures of various forms derived from apothecia. Apothecia range in size from less than a millimeter to approximately 15 cm, and ...

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.
