Verpa Conica
''Verpa conica'', commonly known as the bell morel or the early morel, is a species of fungi in the family Morchellaceae. Sometimes mistaken for a true morel (genus '' Morchella''), this species is an “early morel” characterized by a cap resembling a thimble that is freely attached to the stem. Taxonomy The species was first described under the name ''Phallus conicus'' by Otto Friedrich Müller in 1775. Later authors have moved the taxon to various genera: Persoon placed in '' Leotia'' in 1801, Samuel Frederick Gray transferred it ''Relhanum'' in 1821, while Otto Kuntze moved it to ''Monka'' in 1898. The species was transferred to ''Verpa'' by Olof Swartz in 1814. Description Fruiting bodies have a smooth cap that is bell-shaped or conical, and tall and broad; it is attached to the top of the stem only, the margin of the cap is free – hanging like a skirt. The underside of the cap is tan to dark brown in color. The stem, which measures by thick, is whitish and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verpa
''Verpa'' is a genus of ascomycete fungi related to the morels. Resembling the latter genus in edibility and form, the common name early morels is popular. There are five species in the widespread genus. ''Verpa'' comes from the Latin for ''erection'' or ''little rod'' (also a vulgarity for phallus). Edibility of ''Verpa'' is the same as for ''Morchella'', and are safe if cooked. ''Gyromitra'', by contrast has a couple of dangerously toxic species being Gyromitra esculenta and Gyromitra ambigua. Analysis of the ribosomal DNA of many of the Pezizales showed the genus ''Verpa'' to be closely related to the genus ''Morchella'', and also ''Disciotis''. Thus the three genera are now included in the family Morchellaceae. Species Species include: *''Verpa bohemica'' - early morel. : Edible if cooked. Found in North America, in early spring, April–May in damp places, under poplar *''Verpa conica'' - bell or conic morel. : Edible if cooked. Found in North America, in orcha ...

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 ...

Morel
''Morchella'', the true morels, is a genus of edible sac fungi closely related to anatomically simpler cup fungi in the order Pezizales ( division Ascomycota). These distinctive fungi have a honeycomb appearance due to the network of ridges with pits composing their caps. Morels are prized by gourmet cooks, particularly in Catalan and French cuisine. Due to difficulties in cultivation, commercial harvesting of wild morels has become a multimillion-dollar industry in the temperate Northern Hemisphere, in particular North America, Turkey, China, the Himalayas, India, and Pakistan where these highly prized fungi are found in abundance. Typified by '' Morchella esculenta'' in 1794, the genus has been the source of considerable taxonomical controversy throughout the years, mostly with regard to the number of species involved, with some mycologists recognising as few as three species and others over thirty. Current molecular phylogenetics suggest there might be over seventy speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coniferous
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardwood
Hardwood is wood from dicot trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees). Characteristics Hardwoods are produced by angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought. Hardwood from deciduous species, such as oak, normally shows annual growth rings, but these may be absent in some tropical hardwoods. Hardwoods have a more complex structure than softwoods and are often much slower growing as a result. The dominant feature separating "hardwoods" from softwoods is the presence o ...

Mitrophora Semilibera
''Morchella semilibera'', commonly called the half-free morel, is an edible species of fungus in the family Morchellaceae native to Europe and Asia. DNA analysis has shown that the half-free morels, which appear nearly identical on a macroscopic scale, are a cryptic species complex, consisting of at least three geographically isolated species. Because de Candolle originally described the species based on specimens from Europe, the scientific name ''M. semilibera'' should be restricted to the European species. In 2012, ''Morchella populiphila'' was described from western North America, while Peck's 1903 species name ''Morchella punctipes'' was reaffirmed for eastern North American half-free morels. ''M. semilibera'' and the other half-free morels are closely related to the black morels ('' M. elata'' and others).

Verpa Bohemica
''Verpa bohemica'' is a species of fungus in the family Morchellaceae. Commonly known as the early morel or the wrinkled thimble-cap. The mushroom has a pale yellow or brown thimble-shaped cap— in diameter by long—that has a surface wrinkled and ribbed with brain-like convolutions. The cap hangs from the top of a lighter-colored, brittle stem that measures up to long by thick. Microscopically, the mushroom is distinguished by its large spores, typically 60–80 by 15–18 µm, and the presence of only two spores per ascus. In the field, the mushroom is reliably distinguished from the true morels on the basis of cap attachment: ''V. bohemica'' has a cap that hangs completely free from the stem. Although widely considered edible, some attention should be paid to the correct preparation. Consumption of the mushroom, not correctly prepared lead to reports of poisoning in susceptible individuals. Poisoning symptoms include gastrointestinal upset and lack of mus ...

Septate
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular s ...

Paraphyses
Paraphyses are erect sterile filament-like support structures occurring among the reproductive apparatuses of fungi, ferns, bryophytes and some thallophytes. The singular form of the word is paraphysis. In certain fungi, they are part of the fertile spore-bearing layer. More specifically, paraphyses are sterile filamentous hyphal end cells composing part of the hymenium of Ascomycota and Basidiomycota interspersed among either the asci ASCI or Asci may refer to: * Advertising Standards Council of India * Asci, the plural of ascus, in fungal anatomy * Accelerated Strategic Computing Initiative * American Society for Clinical Investigation * Argus Sour Crude Index * Association of ... or basidia respectively, and not sufficiently differentiated to be called cystidia, which are specialized, swollen, often protruding cells. The tips of paraphyses may contain the pigments which colour the hymenium. In ferns and mosses, they are filament-like structures that are found on sporangi ...

Ascus
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 species can occur in numbers of one (e.g. '' Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. ''Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some ''Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bour ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a 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 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 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 . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
