Pisutiella
''Pisutiella'' is a genus of lichen-forming fungi in the family Teloschistaceae. It contains five species of saxicolous lichen, saxicolous (rock-dwelling), crustose lichens that are found in a variety of environments in the Northern Hemisphere. Taxonomy The genus was circumscription (taxonomy), circumscribed in 2020 by lichenologists Sergey Kondratyuk, László Lőkös, and Edit Farkas, with ''Pisutiella conversa'' assigned as the type species. This species was originally described in 1861 by August von Krempelhuber as ''Callopisma conversum'', and was later known as a member of the large genus ''Caloplaca''. The genus name was chosen by the authors to honour the Slovak lichenologist Ivan Pišút (1935–2017), "to acknowledge his great contribution to our knowledge on lichens of the Carpathians and in recognition of his general contribution to lichenology". ''Pisutiella'' is in the subfamily Caloplacoideae of the family Teloschistaceae. Description The lichen genus ''Pisutiell ...

Teloschistaceae
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family, estimated to contain over 1800 species, was extensively revised in 2013, including the creation or resurrection of 31 genera. It contains three subfamilies: Xanthorioideae, Caloplacoideae, and Teloschistoideae. A fourth subfamily, Brownlielloideae, proposed in 2015, has been shown to be part of the Teloschistoideae. Genera This is a list of the genera contained within the Teloschistaceae, based on a 2020 review and summary of ascomycete classification. Following the genus name is the taxonomic authority, year of publication, and the number of species: *'' Amundsenia'' – 2 spp. *'' Andina'' - 1 sp. *'' Apatoplaca'' – 1 sp. *'' Aridoplaca'' - 1 sp. *'' Athallia'' – 17 spp. *'' Austroplaca'' – 10 spp. *'' Blastenia'' – 11 spp. *'' Brownliella'' – 4 spp. *'' Bryoplaca'' – 3 spp. *'' Calogaya'' – 19 spp. *'' Calop ...

Ellipsoid
An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular axes of symmetry which intersect at a center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal axes'', or simply axes of the ellipsoid. If the three axes have different lengths, the figure is a triaxial ellipsoid (r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diaspore (botany)
In botany, a diaspore is a plant dispersal unit consisting of a seed or spore plus any additional tissues that assist dispersal. In some seed plants, the diaspore is a seed and fruit together, or a seed and elaiosome. In a few seed plants, the diaspore is most or all of the plant, and is known as a tumbleweed. Diaspores are common in weedy and ruderal species. Collectively, diaspores, seeds, and spores that have been modified for migration are known as ''disseminules''. Role in dispersal A diaspore of seed plus elaiosome is a common adaptation to seed dispersal by ants (myrmecochory). This is most notable in Australian and South African sclerophyll plant communities. Typically, ants carry the diaspore to their nest, where they may eat the elaiosome and discard the seed, and the seed may subsequently germinate. A diaspore of seed(s) plus fruit is common in plants dispersed by frugivores. Fruit-eating bats typically carry the diaspore to a favorite perch, where they eat the ...

Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia (basidiomycetes) or paraphyses (ascomycetes). Cystidia are often important for microscopic identification. The subhymenium consists of the supportive hyphae from which the cells of the hymenium grow, beneath which is the hymenophoral trama, the hyphae that make up the mass of the hymenophore. The position of the hymenium is traditionally the first characteristic used in the classification and identification of mushrooms. Below are some examples of the diverse types which exist among the macroscopic Basidiomycota and Ascomycota. * In agarics, the hymenium is on the vertical faces of the gills. * In boletes and polypores, it is in a spongy mass of downward-pointing tubes. * In puffballs, ...

Conidia
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an asexual, non-motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium'') species. The terms microconidia and macroconidia are sometimes used. Conidiogenesis There are two main types of conidium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
