Mycaureola
''Mycaureola'' is a genus of fungi in the family Physalacriaceae of mushrooms. Circumscribed in 1922 by French mycologists René Maire and Émile Chemin, the genus is monotypic, containing the single species ''Mycaureola dilseae''. The fungus is a parasite of the red algal species ''Dilsea carnosa'', on which it causes circular necrotic lesions. Taxonomy ''Mycaureola indica'' was described in a 1957 publication, but the taxon was later transferred to the genus '' Polystigma'' as '' P. indicum''. Molecular phylogenetics placed ''Mycaureola'' in the Physalacriaceae, occupying a subclade with species from the genera ''Rhizomarasmius'', '' Gloiocephala'', ''Xerula'', and ''Oudemansiella ''Oudemansiella'' is a genus of fungi in the family Physalacriaceae.

Physalacriaceae
The Physalacriaceae are a family of fungi in the order Agaricales. Species in the family have a widespread distribution, ranging from the Arctic, ('' Rhizomarasmius''), to the tropics, e.g. '' Gloiocephala'', and from marine sites ('' Mycaureola'') and fresh waters ('' Gloiocephala'') to semiarid forests ('' Xerula''). Description Most species in the Physalacriaceae form fruit bodies with caps and stipes. They have a monomitic hyphal system (wherein only generative hypha are produced), and clamp connections are present in the hyphae. Basidia (spore-bearing cells) are club-shaped with two to four sterigmata. The basidiospores generally have ellipsoidal, spindle-like (fusiform), cylindrical, or tear-drop (lacrimiform) shapes; they are thin-walled, hyaline, and do not react with Melzer's reagent. The family also contains corticioid fungi (in genus '' Cylindrobasidium'') and a secotioid species ('' Guyanagaster necrorhiza''). Taxonomy The family was originally defined by Englis ...

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] |
Dilsea Carnosa
''Dilsea carnosa'', commonly known as the poor man's weather glass or the sea belt, is a species of red algae in the Dumontiaceae family of the order Gigartinales. Taxonomy The species was first described scientifically by Schmidel in 1794, under the name ''Fucus carnosus''. The German botanist Otto Kuntze transferred the species to '' Dilsea'' in 1898. Description This large alga is dark red, flattened and somewhat leathery. It may be 30 cm or more long and 15 cm wide. It is usually not branched but may split. It grows from a small discoid base.Bunker, F.StP. D., Brodie, J.A., Maggs, C.A. and Bunker, Anne R. 2017. ''Seaweeds of Britain and Ireland.'' Second Edition, Wild Nature Press, Plymouth, UK.

Oudemansiella
''Oudemansiella'' is a genus of fungi in the family Physalacriaceae. The genus contains about 15 species that are widely distributed in tropical and temperate regions. Yang and colleagues revised the genus in a 2009 publication, describing several new species and several varieties. They classified species in the genus into four sections based on the structure of the cap cuticle: ''Oudemansiella'', '' Mucidula'', ''Dactylosporina'', and '' Radicatae''. The genus name of ''Oudemansiella'' is in honour of Corneille Antoine Jean Abram Oudemans or Cornelis Antoon Jan Abraham Oudemans (1825–1906), who was a Dutch botanist and physician who specialized in fungal systematics. The genus was circumscribed by Carlos Luis Spegazzini in Anales Soc. Ci. Argent. vol.12 on page 23 in 1881.

Gloiocephala
''Gloiocephala'' is a genus of fungi in the family Physalacriaceae. The genus is widespread, though mainly known from tropical and sub-tropical areas, and contains about 30 species. The mushrooms of this group are very small and grow on stems and leaves of monocotyledonous plants, such as sedges, usually in wet places. In most species their fruiting bodies do not develop into a typical mushroom form - the gills A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are ... are often reduced to vein-like structures or completely missing, and the stipe may be asymmetrical, short or absent. There are five species which grow in Europe: ''G. caricis'', ''G. cerkesii'', ''G. cornelii'', ''G. menieri'' and ''G. pseudocaricis''.

Rhizomarasmius
''Rhizomarasmius'' is a genus of fungi in the family Physalacriaceae, containing about five species. General The genus was created in 2000 by R. H. Petersen to accommodate two species then classified in Marasmius (''M. pyrrhocephalus'' and ''M. undatus''), but which do not belong there due to morphological grounds, including the nature of the cystidia and the way the mushrooms are rooted on a plant substrate. This analysis was backed up in 2006 by DNA comparisons done by Wilson and Desjardin. Unlike most ''Marasmius'' mushrooms, members of ''Rhizomarasmius'' grow on the rhizomes of ferns or flowering plants, and that is the signification of the genus name. Instead of the Marasmiaceae this genus is placed in the Physalacriaceae, a sister clade but a separate family.

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Red Alga
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (Class (biology), class), and mostly consist of multicellular, ocean, marine algae, including many notable seaweed, seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
