Sac Fungi
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) ascomycetes a ...

Sarcoscypha Coccinea
''Sarcoscypha coccinea'', commonly known as the scarlet elf cup, scarlet elf cap, or the scarlet cup, is a species of fungus in the family Sarcoscyphaceae of the order Pezizales. The fungus, widely distributed in the Northern Hemisphere, has been found in Africa, Asia, Europe, North and South America, and Australia. The type species of the genus ''Sarcoscypha'', ''S. coccinea'' has been known by many names since its first appearance in the scientific literature in 1772. Phylogenetic analysis shows the species to be most closely related to other ''Sarcoscypha'' species that contain numerous small oil droplets in their spores, such as the North Atlantic island species ''Sarcoscypha macaronesica, S. macaronesica''. Due to similar physical appearances and sometimes overlapping distributions, ''S. coccinea'' has often been confused with ''Sarcoscypha occidentalis, S. occidentalis'', ''Sarcoscypha austriaca, S. austriaca'', and ''Sarcoscypha dudleyi, S. du ...

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] |
Phylum
In biology, a phylum (; plural: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. Depending on definitions, the animal kingdom Animalia contains about 31 phyla, the plant kingdom Plantae contains about 14 phyla, and the fungus kingdom Fungi contains about 8 phyla. Current research in phylogenetics is uncovering the relationships between phyla, which are contained in larger clades, like Ecdysozoa and Embryophyta. General description The term phylum was coined in 1866 by Ernst Haeckel from the Greek (, "race, stock"), related to (, "tribe, clan"). Haeckel noted that species constantly evolved into new species that seemed to retain few consistent features among themselves and therefore few features that distinguished them as a group ("a self-contained unity" ...

Neolectomycetes
''Neolecta'' is a genus of ascomycetous fungi that have fruiting bodies in the shape of unbranched to lobed bright yellowish, orangish to pale yellow-green colored, club-shaped, smooth, fleshy columns up to about 7 cm tall. The species share the English designation "Earth tongues" along with some better-known fungi (e.g. ''Geoglossum'', ''Microglossum'') with a similar general form, but in fact they are only distantly related. ''Neolecta'' is the only genus belonging to the family Neolectaceae, which is the only family belonging to the order Neolectales. ''Neolectales'', in turn, is the only order belonging to the class Neolectomycetes, which belongs to the subdivision Taphrinomycotina of the Ascomycota. ''Neolecta'' is found in Asia, North America, Northern Europe and southern Brazil. The species all live in association with trees, and at least one, ''N. vitellina'', grows from rootlets of its host, but it is not known whether the fungus is parasitic, saprotrophic, or mutu ...

Archaeorhizomyces
Archaeorhizomycetes is a class of fungi in the subdivision Taphrinomycotina of the Ascomycota. So far, the class has only one described order, Archaeorhizomycetales, family, Archaeorhizomycetaceae, and genus, ''Archaeorhizomyces''. The class was first described by a team led by Anna Rosling in 2011. Species in the class are globally distributed, and grow in soil and around roots. Specific known host trees of various Archaeorhizomyces species include hemlock, spruce, pine and heather, but other species colonise hardwoods generally. The precise ecological role of the taxa is uncertain. While originally found to be seasonal, suggesting it was dependent on carbon compounds from the roots, when grown in culture, ''Archaeorhizomyces finlayi'', was shown to be able to grow using either glucose or cellulose as its sole source of carbon, suggesting "that it may be involved in decomposition and not require direct carbon transfer from the plant through symbiosis".

Taphrinomycotina
The Taphrinomycotina are one of three subdivisions constituting the Ascomycota (fungi that form their spores in a sac-like ascus) and is more or less synonymous with the slightly older invalid name Archiascomycetes (sometimes spelled Archaeascomycetes; archea = ancient). Recent molecular studies suggest that the group is monophyletic and basal to the rest of the Ascomycota. The major taxa are Schizosaccharomycetes, Taphrinomycetes, Neolectomycetes, and Pneumocystis. The Schizosaccharomycetes are the yeasts (e.g. ''Schizosaccharomyces'') that reproduce by fission rather than budding, unlike most other yeasts, many of which are in the subdivision Saccharomycotina. The Taphrinomycetes are dimorphic plant parasites (e.g. ''Taphrina'') with both a yeast state and a filamentous (hyphal) state in infected plants. They characteristically infect leaves, catkins, and branches, not roots. Taphrinomycetes form asci but no ascomata. The Neolectomycetes are species in a single genus, ''N ...

Saccharomycetes
Saccharomycetes belongs to the Ascomycota division of the kingdom Fungi. It is the only class in the subdivision Saccharomycotina, the budding yeasts. Saccharomycetes contains a single order, Saccharomycetales Saccharomycetales belongs to the kingdom of Fungi and the division Ascomycota. It is the only order in the class Saccharomycetes. There are currently 13 families recognized as belonging to Saccharomycetales. GBIF also includes; Alloascoideacea .... Saccharomycetes are known for being able to comprise a monophyletic lineage with a single order of about 1,000 known species. These yeasts live as decomposers, feeding on dead and decaying wood, leaves, litter, and other organic matter. According to Suh et al. (2006), "yeasts are responsible for important industrial and biotechnological processes, including baking, brewing and synthesis of recombinant proteins," with Saccharomycetes being model organisms in research. Asia is likely to be the origin of the source. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saccharomycotina
Saccharomycotina is a subdivision (subphylum) of the division (phylum) Ascomycota in the kingdom Fungi. It comprises most of the ascomycete yeasts. The members of Saccharomycotina reproduce by budding and they do not produce ascocarps (fruiting bodies). The subdivision includes a single class: Saccharomycetes, which again contains a single order: Saccharomycetales. Notable members of Saccharomycotina are the baker's yeast ''Saccharomyces cerevisiae'' and the genus '' ''Candida'''' that includes several human pathogens. Etymology The name comes from the Greek word σάκχαρον (''sákkharon''), meaning "sugar" and μύκης (''mukēs'') meaning "fungus". History and economic importance Historical records from ancient Egypt and China describe the processes of brewing and baking from 10,000 to 8,000 years ago, and the production of fermented beverages and foods seems to have paralleled the beginning of agriculture. In the 1850s, Louis Pasteur demonstrated that yeasts a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
