Pisorisporium
''Pisorisporium'' is a genus of freshwater and terrestrial fungi in the family Pisorisporiaceae and order Pisorisporiales in the subclass Pisorisporiomycetidae. Etymology The name ''Pisorisporium'' is derived from ''Pisorum'' (Latin), meaning peas in a pod, which refers to the numerous guttules (a small drop or drop-like particle) arranged in a chain within ascospores and also ''spora'' (another Latin word), referring to the ascospores. Description ''Pisorisporium'' genera usually have an ascomata (the asci-bearing fruiting body) which is non-stromatic (not encased in the stroma), immersed, gradually erumpent (bursting through a surface) to superficial and solitary or in small groups or rows. It is also papillate (has a small, elongated protuberance on the surface) or with a short beak. It is glabrous (hair-less) with a venter (a protuberant, usually hollow structure) which is subglobose to broadly conical in shape and laterally or basally flattened and upright or lying obliqu ...

Pisorisporiaceae
Pisorisporiales is an order of fungi within the division Ascomycota, subdivision Pezizomycotina, class Sordariomycetes and its own subclass Pisorisporiomycetidae. It contains a single family Pisorisporiaceae and 2 genera; '' Achroceratosphaeria'' (2 species) and ''Pisorisporium'' (2 species). History A freshwater and terrestrial based fungal genus ''Achroceratosphaeria'' was initially placed in Sordariomycetes incertae sedis (Réblová et al. 2010). Then phylogenetic analyses of fungal strains from an aquatic environment, including LSU, SSU and RPB2 sequence data, grouped them in a monophyletic clade with ''Achroceratosphaeria'' species (Réblová et al. 2015a). Four specimens of an unidentified fungus were collected on deciduous wood submerged in fresh water in France and Belgium during the years 2006–2014. The new taxa were placed in the novel genus, ''Pisorisporium'' and a new family, ''Pisorisporiaceae'' was then erected to accommodate genera ''Pisorisporium'' and ''Achr ...

Sordariomycetes Genera
Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota). It is the second-largest class of Ascomycota, with a worldwide distribution that mostly accommodates terrestrial based taxa, although several can also be found in aquatic habitats. Some are phytopathogens that can cause leaf, stem, and root diseases in a wide variety of hosts, while other genera can cause diseases in arthropods and mammals. The name Sordariomycetes is derived from the Latin ''sordes'' (filth) because some species grow in animal feces, though growth habits vary widely across the class. In 2013, it consisted of 3 subclasses, 12 orders, 600 genera and 3000 species, Then by 2015, it had 3 subclasses, 28 orders, 90 families and 1344 genera. This has increased to 4 subclasses and 54 orders in 2020. It then increased to 6 subclasses and 54 orders in 2023. In May 2023, the GBIF listed 26,295 species in Sordariomycetes. Sordariomycetes generally produce their asci in perithecial fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucilage
Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage. It is a polar glycoprotein and an exopolysaccharide. Mucilage in plants plays a role in the storage of water and food, seed germination, and thickening membranes. Cacti (and other succulents) and flax seeds are especially rich sources of mucilage. Occurrence Exopolysaccharides are the most stabilising factor for microaggregates and are widely distributed in soils. Therefore, exopolysaccharide-producing "soil algae" play a vital role in the ecology of the world's soils. The substance covers the outside of, for example, unicellular or filamentous green algae and cyanobacteria. Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life cycle. It occu ...

Yunnan
Yunnan; is an inland Provinces of China, province in Southwestern China. The province spans approximately and has a population of 47.2 million (as of 2020). The capital of the province is Kunming. The province borders the Chinese provinces of Guizhou, Sichuan, Autonomous regions of China, autonomous regions of Guangxi and Tibet Autonomous Region, Tibet, as well as Southeast Asian countries Myanmar (Burma), Vietnam, and Laos. Yunnan is China's fourth least developed province based on disposable income per capita in 2014. Yunnan is situated in a mountainous area, with high elevations in the Northwest and low elevations in the Southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys as much as . Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of Vascular plant, higher plants in China, Yunnan has perhaps 17, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acer Pseudoplatanus
''Acer pseudoplatanus'', known as the sycamore in the British Isles and as the sycamore maple in the United States, is a species of maple native to Central Europe and Western Asia. It is a large deciduous, broad-leaved tree, tolerant of wind and coastal exposure. Although native to an area ranging from France eastward to Ukraine, northern Turkey and the Caucasus, and southward to the mountains of Italy and northern Iberia, the sycamore establishes itself easily from seed and was introduced to the British Isles by 1500. It is now Naturalisation (biology), naturalised there and in other parts of Europe, North America, Australia and New Zealand, where it may become an invasive species. The sycamore can grow to a height of about and the branches form a broad, rounded Crown (botany), crown. The Bark (botany), bark is grey, smooth when young and later flaking in irregular patches. The leaves grow on long Petiole (botany), leafstalks and are large and List of botanical terms#palmate, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
