Chaetothiersia
''Chaetothiersia'' is a fungal genus in the family Pyronemataceae. It is monotypic, containing the single species ''Chaetothiersia vernalis'' collected from the northern High Sierra Nevada of California. It has been found growing in groups on the decaying wood and bark of the conifer ''Abies magnifica''. Description This species is characterized by having stiff brown hairs on the surface of the ectal excipulum, the outer layer of the apothecium. The ectal excipulum is thin, and made of roughly spherical to somewhat spherical/angular cells. Its ascospores are smooth, and do not contain oil droplets. Etymology The etymology of the generic name is derived from the Greek ''chaeto'', meaning hairy (a reference to both the external hairs on the cups and to Dr. Thiers' first name), and "thiersia", in honor of mycologist Harry Thiers, one of the first to collect this specimen. Lookalikes Genera with species that bear a resemblance to ''C. vernalis'' include ''Geopora'', '' Humaria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyronemataceae
The Pyronemataceae are a family of fungi in the order Pezizales. It is the largest family of the Pezizales, encompassing 75 genera and approximately 500 species. Phylogenetic analyses does not support the prior classifications of this family, and suggest that the family is not monophyletic as it is currently circumscribed. Morphology Members of the family are diverse in ascomatal or cleistothecial form. Individual taxa may be sessile (without a stipe) to shortly stipitate, cupulate (cup-shaped), discoid (disc-shaped), pulvinate (cushion-shaped), or with turbinate (turban-shaped) epigeous apothecia. Also, taxa may be sub-hypogeous to hypogeous with closed, folded, or solid ascomata. Apothecia may range in size from less than 1 mm up to 12 cm in diameter, and may be brightly colored due to carotenoid pigments. Genera of the Pyronemataceae lack unifying macroscopic or microscopic characteristics; this lack of uniting characters has led various authors to propose a variety ...

Harry Delbert Thiers
Harry Delbert Thiers (January 22, 1919 in Fort McKavett, Texas – August 8, 2000 in Ohio) was an American mycologist who studied and named many fungi native to North America, particularly California. Thiers taught mycology at San Francisco State University. He comprehensively revised and expanded on the North American collection of boletes and named many new species. Species authored include: *'' Suillellus amygdalinus'' *''Boletus barrowsii'' *'' Xerocomellus dryophilus'' *''Rubroboletus pulcherrimus'' *''Gymnopilus luteoviridis'' *''Leccinum manzanitae ''Leccinum manzanitae'' is an edible species of bolete fungus in the family Boletaceae.

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a 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 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 group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Monotypic Ascomycota Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

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.

Mycologist
Mycology is the branch of biology concerned with the study of fungus, fungi, including their genetics, genetic and biochemistry, biochemical properties, their Taxonomy (biology), taxonomy and ethnomycology, their use to humans, including as a source for tinder, traditional medicine, Edible mushroom, food, and entheogens, as well as their dangers, such as poison, toxicity or fungal infection, infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz ...

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 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 "bourrelet ...
