Astraeus Pteridis
''Astraeus pteridis'', commonly known as the giant hygroscopic earthstar, is a species of false earthstar in the family Diplocystaceae. It was described by American mycologist Cornelius Lott Shear in 1902 under the name ''Scleroderma pteridis''. Sanford Myron Zeller transferred it to ''Astraeus'' in a 1948 publication. It is found in North America. ''A. pteridis'' was previously frequently confused with the supposedly cosmopolitan '' A. hygrometricus'', now shown to be found only in Europe. Distribution A molecular phylogenetic study from 2013 resulted in the application of the name ''A. pteridis'' to the larger ''Astraeus'' found in the Pacific Northwest region of North America. ''A. pteridis'' has also been found in the Canary Islands, Madeira, and Argentina, which share historical connections to Lusitania. It may be widely distributed or have been translocated. Morphology ''A. pteridis'' closely resembles ''A. hygrometricus'', though it is larger, reaching 5 to 15 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Translocation
Translocation in wildlife conservation is the capture, transport and release or introduction of species, habitats or other ecological material (such as soil) from one location to another. It contrasts with reintroduction, a term which is generally used to denote the introduction into the wild of species from captive stock. The International Union for the Conservation of Nature (IUCN) catalogues translocation projects for threatened species around the globe. Overview Translocation can be an effective management strategy and important topic in conservation biology, but despite their popularity, translocations are a high‐cost endeavor with a history of failures. It may decrease the risk of extinction by increasing the range of a species, augmenting the numbers in a critical population, or establishing new populations. Translocation may also improve the level of biodiversity in the ecosystem. Translocation may be expensive and is often subject to public scrutiny, particularly ...

Fungi Of North America
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'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boletales
The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and until recently, the Boletales were thought to only contain boletes. The Boletales are now known to contain distinct groups of agarics, puffballs, and other fruiting-body types. Taxonomy The order Boletales originally was created to describe boletes, but based on micromorphological and molecular phylogenetic characteristics, a large number of nonbolete species have recently been reclassified to belong to this group, as well. The order also includes some gilled mushrooms, in the families Gomphidiaceae, Serpulaceae, Tapinellaceae, Hygrophoropsidaceae, and Paxillaceae, which often have the same flesh texture as the boletes, spore-bearing tissue which is also easily separable from the cap, and similar microscopic characteristics of spores and cystidia. Taxonomic studies using secondary metabolites and later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MycoBank
MycoBank is an online database, documenting new mycological names and combinations, eventually combined with descriptions and illustrations. It is run by the Westerdijk Fungal Biodiversity Institute in Utrecht. Each novelty, after being screened by nomenclatural experts and found in accordance with the ICN ( International Code of Nomenclature for algae, fungi, and plants), is allocated a unique MycoBank number before the new name has been validly published. This number then can be cited by the naming author in the publication where the new name is being introduced. Only then, this unique number becomes public in the database. By doing so, this system can help solve the problem of knowing which names have been validly published and in which year. MycoBank is linked to other important mycological databases such as ''Index Fungorum'', Life Science Identifiers, Global Biodiversity Information Facility (GBIF) and other databases. MycoBank is one of three nomenclatural repositories r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hygroscopy
Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption or adsorption from the surrounding environment, which is usually at normal or room temperature. If water molecules become suspended among the substance's molecules, adsorbing substances can become physically changed, e.g., changing in volume, boiling point, viscosity or some other physical characteristic or property of the substance. For example, a finely dispersed hygroscopic powder, such as a salt, may become clumpy over time due to collection of moisture from the surrounding environment. ''Deliquescent'' materials are sufficiently hygroscopic that they absorb so much water that they become liquid and form an aqueous solution. Etymology and pronunciation The word ''hygroscopy'' () uses combining forms of '' hygro-'' and '' -scopy''. Unlike any other ''-scopy'' word, it no longer refers to a viewing or imaging mode. It did begin that way, with the word ''hygroscope'' referring in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Areolate
Lichens are composite organisms made up of multiple species: a fungal partner, one or more photosynthetic partners, and sometimes a basidiomycete yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. Lichenologists have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Of these, crustose, foliose and fruticose are the most commonly encountered. With the exception of calicioid lichens, growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the photobiont that determines the lichen's morphology. In some growth forms, the outermost layer of the thallus consists of tightly woven fungal . This layer, known as the cortex, may be found ...

Lusitania
Lusitania (; ) was an ancient Iberian Roman province located where modern Portugal (south of the Douro river) and a portion of western Spain (the present Extremadura and the province of Salamanca) lie. It was named after the Lusitani or Lusitanians, Lusitanian people (an Proto-Indo-Europeans, Indo-European people). Its capital was ''Emerita Augusta'' (currently Mérida, Spain), and it was initially part of the Roman Republic province of Hispania Ulterior, before becoming a province of its own in the Roman Empire. Romans first came to the territory around the mid-2nd century BC. A Lusitanian War, war with Lusitanian tribes followed, from 155 to 139 BC. In 27 BC, the province was created. Lusitania was and is often used as an alternative name for Portugal. Origin of the name The etymology of the name of the Lusitanians, Lusitani (who gave the Roman province its name) remains unclear. Popular etymology connected the name to a supposed Roman demigod Lusus, whereas some early-mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanford Myron Zeller
Sanford Myron Zeller (19 October 1885 – 4 November 1948) was an American mycologist. Born in Coldwater, Michigan, Zeller was educated at Lawrence College in Wisconsin, then Greenville College in Illinois, from which he received a Bachelor of Science degree in 1909. He earned his doctorate in botany in 1917 at Washington University in St. Louis, and two years later started a 29-year stint as a plant pathologist and professor at the Oregon Agricultural Experiment Station in Corvallis, Oregon. He published over 150 scientific papers during his career. Zeller specialized in the gasteroid fungi. Independently, he described 3 orders, 9 families, 7 genera, 81 species, and published 29 new names and combinations, as well as 3 genera, 62 species, and 59 combinations in collaborations with other scientists. Zeller was the associate editor of the scientific journal ''Phytopathology'' from 1924 to 1930. Eponymous taxa *'' Aleurodiscus zelleri'' Burt 1926 *'' Armillaria zelleri'' D.E. St ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...
