Psathyrella Longipes
''Psathyrella longipes'', the tall Psathyrella, is a species of agaric fungus in the family Psathyrellaceae and the brittlestem genus, ''Psathyrella''. It was originally described as ''Hypholoma longipes'' by Charles Horton Peck in 1895; Alexander H. Smith transferred it to ''Psathyrella'' in 1941. As its name implies, the tall Psathyrella is unusual in its genus in having a relatively long stipe, 5-12cm long and 2-6mm thick. Its cap is 2.5-4.5cm in diameter and conical, and has a "veil" of creamy-white fragments which contrast with its basic dull brown colour. The tall Psathyrella has an almost world-wide distribution: reports to iNaturalist iNaturalist is a social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe. iNaturalist may be accessed via its website or from its mobile applic ... show it as present in almost every country in Europe and North Africa, in most states ...

Charles Horton Peck
Charles Horton Peck (March 30, 1833 – July 11, 1917) was an American mycologist of the 19th and early 20th centuries. He was the New York State Botanist from 1867 to 1915, a period in which he described over 2,700 species of North American fungi. Biography Charles Horton Peck was born on March 30, 1833, in the northeastern part of the town Sand Lake, New York, now called Averill Park. After suffering a light stroke early in November 1912 and then a severe stroke in 1913, he died at his house in Menands, New York, on July 11, 1917. In 1794, Eleazer Peck (his great grandfather) moved from Farmington, Conn. to Sand Lake, NY attracted by oak timber that was manufactured for the Albany market. Later on, Pamelia Horton Peck married Joel B., both from English descent, and became Charles Peck parents (Burnham 1919; Atkinson 1918). Even though his family was rich and locally prominent, his education was provincial (Haines 1986). During his childhood, he used to enjoy fishing and h ...

Agaric
An agaric () is a type of fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. In the UK, agarics are called "mushrooms" or "toadstools". In North America they are typically called "gilled mushrooms". "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically, agaric meant 'tree-fungus' (after Latin ''agaricum''); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name ''Agaricus'' for gilled mushrooms. Most species of agaricus belong to the order Agaricales in the subphylum Agaricomycotina. The exceptions, where agarics have evolved independently, feature largely in the orders Russulales, Boletales, Hymenochaetales, and several other groups of basidiomycetes. Old systems of classification placed all agarics in the Agaricales and some (mostly older) sources use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psathyrellaceae
The Psathyrellaceae are a family of dark-spored agarics that generally have rather soft, fragile fruiting bodies, and are characterized by black, dark brown, rarely reddish, or even pastel-colored spore prints. About 50% of species produce fruiting bodies that dissolve into ink-like ooze when the spores are mature via autodigestion. Prior to phylogenetic research based upon DNA comparisons, most of the species that autodigested were classified as Coprinaceae, which contained all of the inky-cap mushrooms. However, the type species of ''Coprinus'', '' Coprinus comatus'', and a few other species, were found to be more closely related to Agaricaceae. The former genus ''Coprinus'' was split between two families, and the name "Coprinaceae" became a synonym of Agaricaceae in its 21st-century phylogenetic redefinition. Note that in the 19th and early 20th centuries the family name Agaricaceae had far broader application, while in the late 20th century it had a narrower application. The ...

Psathyrella
''Psathyrella'' is a large genus of about 400 species, and is similar to the genera '' Coprinellus'', ''Coprinopsis'', ''Coprinus'' and ''Panaeolus'', usually with a thin cap and white or yellowish white hollow stem. The caps do not self digest as do those of ''Coprinellus'' and ''Coprinopsis''. Some also have brown spores rather than black. These fungi are often drab-colored, difficult to identify, and all members are considered inedible or worthless (for eating) and so they are often overlooked. However they are quite common and can occur at times when there are few other mushrooms to be seen. The first report of a gilled mushroom fruiting underwater is ''Psathyrella aquatica''. The genus name ''Psathyrella'' is a diminutive form of ''Psathyra'', derived from the Greek word ψαθυρος, ''psathuros'' 'friable'. The type species of ''Psathyrella'' is ''Psathyrella gracilis'', which is now known as ''Psathyrella corrugis''. Characteristics In order to identify the species ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander H
Alexander is a male given name. The most prominent bearer of the name is Alexander the Great, the king of the Ancient Greek kingdom of Macedonia (ancient kingdom), Macedonia who created one of the largest empires in ancient history. Variants listed here are Aleksandar, Aleksander and Aleksandr. Related names and diminutives include Iskandar, Alec, Alek, Alex, Alexandre (given name), Alexandre, Aleks (given name), Aleks, Aleksa (given name), Aleksa and Sander (name), Sander; feminine forms include Alexandra, Alexandria (given name), Alexandria, and Sasha (name), Sasha. Etymology The name ''Alexander'' originates from the (; 'defending men' or 'protector of men'). It is a compound of the verb (; 'to ward off, avert, defend') and the noun (, genetive, genitive: , ; meaning 'man'). It is an example of the widespread motif of Greek names expressing "battle-prowess", in this case the ability to withstand or push back an enemy shield wall, battle line.

Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or universal ve ...

List Of Psathyrella Species
This is a list of ''Psathyrella'' species. Many of its members were formerly classified in the genera ''Hypholoma'', ''Psilocybe'', and '' Stropharia''. Also some well-known species have been moved to new genera, for instance ''Psathyrella'' ''spadicea'' is now '' Homophron spadiceum''. '' Lacrymaria lacrymabunda'' has often been classified as a ''Psathyrella''. According to one 2008 estimate, the genus contains about 400 species. In 2020 many members of the family Psathyrellaceae were reclassified by the German mycologists Dieter Wächter & Andreas Melzer based on phylogenetic analysis. This study created the new genera Britzelmayria, Candolleomyces and Olotia and placed numerous former ''Psathyrella'' species within them. Notable changes include ''Psathyrella candolleana'' being reclassified as '' Candolleomyces candolleanus'' and ''Psathyrella multipedata'' being reclassified as '' Britzelmayria multipedata.''

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] |
Fungi Described In 1895
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] |
