Helvellaceae
The Helvellaceae are a family of ascomycete fungi, the best-known members of which are the elfin saddles of the genus '' Helvella''. Originally erected by Elias Magnus Fries in 1823 as ''Elvellacei'', it contained many genera. Several of these, such as ''Gyromitra'' and '' Discina'', have been found to be more distantly related in a molecular study of ribosomal DNA by mycologist Kerry O'Donnell in 1997, leaving a much smaller core clade now redefined as Helvellaceae. Instead, this narrowly defined group is most closely related to the true truffles of the Tuberaceae. Although the ''Dictionary of the Fungi'' (10th edition, 2008) considered the Helvellaceae to contain six genera and 63 species, genetic analysis has shown that ''Leucangium'', previously classified in this family, is more closely related to the 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 specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helvella Crispa
''Helvella crispa'', also known as the white saddle, elfin saddle or common helvel, is an ascomycete fungus of the family Helvellaceae. The mushroom is readily identified by its irregularly shaped whitish cap, fluted stem, and fuzzy undersurfaces. It is found in eastern North America and in Europe, near deciduous trees in summer and autumn. Etymology The fungus was originally described as ''Phallus crispus'' by the naturalist Giovanni Antonio Scopoli in 1772. Its specific epithet is Latin adjective ''crispa'' 'wrinkled' or 'curly'. The generic name was originally a type of Italian herb but became associated with morels.Nilsson S, Persson O.(1977) ''Fungi of Northern Europe 1: Larger Fungi (Excluding Gill Fungi)''. pp. 36-37. Penguin Books. Description ''Helvella crispa'' is creamy white in colour, 6–13 cm (2½–5 in) in length, with a cap 2–5 cm (1–2 in) in diameter. It is striking due to its irregularly shaped lobes on the cap, but with a robus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helvella
''Helvella'' is a genus of ascomycete fungus of the family Helvellaceae. The mushrooms, commonly known as elfin saddles, are identified by their irregularly shaped caps, fluted stems, and fuzzy undersurfaces. They are found in North America and in Europe. Well known species include the whitish '' H. crispa'' and the grey '' H. lacunosa''. They have been reported to cause gastrointestinal symptoms when eaten raw. Description Species in ''Helvella'' have fruiting bodies (technically ascocarps) that grow above the ground, and usually have stems. The cup-like fruiting body (the ''apothecium'') can assume a variety of forms: it may be shaped like an ear (''auriculate''), or a saddle; it may be convex or irregularly lobed and bent. The spore-bearing surface, the hymenium, can be smooth, wavy or wrinkled and can range in color from white to black or various shades of gray or brown. Similarly, the outer surface of the fruiting bodies can be smooth, ribbed, or have minute hairlike projec ... [...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 ...

Tuberaceae
The Tuberaceae () are a family of mycorrhizal fungi in the order Pezizales, that evolved during or after the first major radiation of Angiosperms in the Jurassic period (140–180 million years ago, Mya). It includes the genus ''Tuber'', which includes the so-called "true" truffles. It was characterized by the Belgian botanist Barthélemy Charles Joseph du Mortier in 1822.

These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments.

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 ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Ascomycota
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) ascomyce ...
