Verpa Digitaliformis
''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 ...

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 either ... [...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 ...

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "puffball", "stinkhorn", and " morel", and gilled mushrooms themselves are often called "agarics" in refere ...

Verpa Speciosa
''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.

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 muscular ...

Morchellaceae
The Morchellaceae are a family of ascomycete fungi in the order Pezizales. According to a standard reference work, the family has contained at least 49 species distributed among four genera. However, in 2012, five genera that produce ascoma that are sequestrate and hypogeous were added. The best-known members are the highly regarded and commercially picked true morels of the genus ''Morchella'', the thimble morels of the genus ''Verpa'', and a genus of cup-shaped fungi ''Disciotis''. The remaining four genera produce the sequestrate fruit bodies. Analysis of the ribosomal DNA of many of the Pezizales showed the three genera ''Verpa'', ''Morchella'', and ''Disciotis'' to be closely related. Thus they are now included in the family Morchellaceae. Genera ''Costantinella'' (anamorph) ''Disciotis'' (terrestrial) ''Morchella'' (terrestrial) ''Verpa'' (terrestrial) ''Kalapuya'' (hypogeous) ''Imaia'' (hypogeous) ''Leucangium'' (hypogeous) ''Fischerula'' (hypogeous) Description Other ...

Disciotis
''Disciotis'' is a genus of fungi in the family Morchellaceae. Members of this family, characterized by their cup- or bowl-shaped apothecia, have a widespread distribution, especially in northern temperate regions. Description ''Disciotis'' has a cupulate (cup-shaped) pileus with vein-like hymenial folds and a small to non-existent stipe. Species The type species is ''Disciotis venosa'', originally described as ''Peziza venosa'' by Christian Hendrik Persoon in 1801. Other species described in the genus include: *''Disciotis ferruginascens'' Boud. *''Disciotis maturescens'' Boud. (1891) *''Disciotis rufescens'' R. Heim (1934) It has been suggested that these species (and variants not listed above) all represent a single, morphologically variable species.Korf RP. (1972).

Morchella
''Morchella'', the true morels, is a genus of edible ascomycota, sac fungi closely related to anatomically simpler Cup fungus, cup fungi in the order Pezizales (division (mycology), division Ascomycota). These distinctive fungi have a honeycomb appearance due to the network of ridges with pits composing their cap (mycology), caps. Morels are prized by gourmet cooks, particularly in Catalan cuisine, Catalan and French cuisine. Due to difficulties in Fungiculture, 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 taxonomy (biology), taxonomical controversy throughout the years, mostly with regard to the number of species involved, with some mycologists recognising as few as three ...

Ribosomal DNA
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments. In the human genome there are 5 chromosomes with nucleolus organizer regions: the acrocentric chromosomes 13 (RNR1), 14 ( RNR2), 15 ( RNR3), 21 (RNR4) and 22 (RNR5). The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans. But the genes that encode for rRNA are highly conserved across the domains, with only the copy numbers involved for the genes having varying numbers per species. In Bacteria, Archaea, and chloroplasts the rRNA is composed of different (smaller) units, the large (23S) ribosomal RNA, 16S ribosomal RNA and 5S rRNA. The 16S rRNA is widely used for phylogenetic studies. Eukaryotes The rRNA transcribed from the approximately 600 rDNA repeats forms the most abundant section of RNA found in cells ...

Adans
Michel Adanson (7 April 17273 August 1806) was an 18th-century French botanist and naturalist who traveled to Senegal to study flora and fauna. He proposed a "natural system" of taxonomy distinct from the binomial system forwarded by Linnaeus. Personal history Adanson was born at Aix-en-Provence. His family moved to Paris in 1730. After leaving the Collège Sainte-Barbe he was employed in the cabinets of R. A. F. Réaumur and Bernard de Jussieu, as well as in the Jardin des Plantes, Paris. He attended lectures at the Jardin du Roi and the Collège Royal in Paris from 1741 to 1746. At the end of 1748, funded by a director of the Compagnie des Indes, he left France on an exploring expedition to Senegal. He remained there for five years, collecting and describing numerous animals and plants. He also collected specimens of every object of commerce, delineated maps of the country, made systematic meteorological and astronomical observations, and prepared grammars and dictionarie ...
