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 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 chrom ... 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 '' Leuc ...

Fungi
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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) ascom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pezizomycotina
Pezizomycotina make up most of the Ascomycota fungi and include most lichenized fungi too. Pezizomycotina contains the filamentous ascomycetes and is a subdivision of the Ascomycota (fungi that form their spores in a sac-like ''ascus''). It is more or less synonymous with the older taxon Euascomycota. These fungi reproduce by fission rather than budding and this subdivision includes almost all the ascus fungi that have fruiting bodies visible to the naked eye (exception: genus '' Neolecta'', which belongs to the Taphrinomycotina). See the taxobox for a list of the classes that make up the Pezizomycotina. The old class Loculoascomycetes (consisting of all the bitunicate 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 ...

Pezizomycetes
Pezizomycetes are a class of fungi within the division Ascomycota. Pezizomycetes are apothecial fungi, meaning that their spore-producing/releasing bodies ( ascoma) are typically disk-like, bearing on their upper surfaces a layer of cylindrical spore-producing cells called asci, from which the spores are forcibly discharged. Important groups include: cup fungi ( Peziza), morels, Elfin saddle {{Short description, Name for several species of fungus The common name elfin saddle is given to a number of Ascomycete fungi in the order Pezizales. These medium to small fungi often have irregular saddle-shaped caps. Species include: *''Gyrom ...s, and truffles.

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, a ...

Helen Margaret Gilkey
Helen Margaret Gilkey (1886–1972) was an American mycologist and botanist, as well as a botanical illustrator and watercolor artist She was born on March 6, 1886 in Montesano, Washington and moved to Corvallis, Oregon with her family in 1903. She died in 1972 at the age of 86. Education Gilkey received both a bachelor's and a master's degree from Oregon Agricultural College (now Oregon State University) for her studies in botany (including mycology) and botanical illustration. She continued her studies at the University of California, Berkeley, and in 1915 she became the first woman to receive a Ph.D. in botany there. Gilkey's doctoral dissertation focused on the taxonomy of North American truffles (order Tuberales), and her published dissertation remains an important contribution to the study of truffle taxonomy in North America. Career After completing her doctoral studies, Gilkey worked as a scientific illustrator. She contributed original illustrations to Willis Linn Je ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
