Catathelasma Evanescens
''Catathelasma evanescens'' is a species of fungus in the family Biannulariaceae, and the type species of the genus ''Catathelasma''. The species was described by Ruth Ellen Harrison Lovejoy in 1910. Description and Distribution The genus includes the commoner '' C. imperiale'' and ''C. ventricosum'', but the type species, ''C. evanescens'', seems extremely rare. In 1914 it was only known from the location of the initial find, which is at an altitude of 3500 m. in the Medicine Bow Mountains of Wyoming. It is distinguished from the other species because the gills are fairly distant ("subdistant") and because it has a large persistent volva around the base of the stipe. The species name may refer to the evanescent Evanescent may refer to: * Evanescent (dermatology), a class of skin lesions * "Evanescent" (song), a song by Vamps * Evanescent wave, a term applied to electromagnetic waves that decay exponentially See also * Evanescence (other) Ev ... ring.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biannulariaceae
The Biannulariaceae are a family of fungi in the order Agaricales. The family contains three genera. All species form agaricoid basidiocarps (gilled mushrooms). The family was originally described to accommodate the single genus ''Catathelasma ''Catathelasma'' is a genus of fungi in the family (biology), family Biannulariaceae.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Catathelasma
''Catathelasma'' is a genus of fungi in the family (biology), family Biannulariaceae. Basidiocarps (fruit bodies) are agaric, agaricoid, with a conspicuous Universal veil, veil (leaving a double ring on the stem), Lamella (mycology), adnate to decurrent lamellae (mycology), lamellae, and amyloid (mycology), amyloid basidiospores. The genus is separated on DNA characteristics as well as morphology. Species are known from North America, Europe, and Asia and are ectomycorrhizal, forming an association with the living roots of trees. Taxonomy The genus ''Catathelasma'' was originally described in 1910 by American botanist and mycologist Ruth Ellen Harrison Lovejoy with ''Catathelasma evanescens, C. evanescens'' as the type species. in 1922 the Austrian botanist Günther Beck von Mannagetta und Lerchenau referred the European species ''Armillaria imperialis'' to his new genus ''Biannularia''. For a time ''Catathelasma'' and ''Biannularia'' were regarded as separate (though closely r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catathelasma Imperiale
''Catathelasma imperiale'' is a species of agaric (gilled mushroom) in the family Biannulariaceae. Basidiocarps (fruit bodies) are stocky, with a double annulus (ring), and a tapering to rooting stipe (stem). The species is ectomycorrhizal with conifers and is found in continental Europe and Asia. Reports from North America are unconfirmed and may refer to '' Catathelasma evanescens'' or similar species. Fruit bodies are edible and collected for food in China and elsewhere. The species is widespread but uncommon and is assessed as globally "near threatened" on the IUCN Red List of Threatened Species. Taxonomy ''Catathelasma imperiale'' was first described from Sweden in 1845 by Norwegian botanist Nicolai Lund as ''Agaricus imperialis'', but this name is illegitimate since two earlier (and different) fungi had already been described under the same name. The species was first legitimately described, as ''Armillaria imperialis'', by Finnish mycologist Petter Adolf Karsten in 18 ...

Medicine Bow Mountains
The Medicine Bow Mountains are a mountain range in the Rocky Mountains that extend from northern Colorado into southern Wyoming. The northern extent of this range is the sub-range the Snowy Range. From the northern end of Colorado's Never Summer Mountains, the Medicine Bow mountains extend north from Cameron Pass along the border between Larimer and Jackson counties in Colorado and northward into south central Wyoming. In Wyoming, the range sits west of Laramie, in Albany and Carbon counties to the route of the Union Pacific Railroad and U.S. Interstate 80. The mountains often serve as a symbol for the city of Laramie. The range is home to Snowy Range Ski Area. The highest peak in the range is Clark Peak (), located in the Rawah Wilderness along the southern end of the range in Northern Colorado. Much of the range is located within the Medicine Bow National Forest in Wyoming. The highest peak on the Wyoming side is Medicine Bow Peak (). The range is drained along the west ...

Volva (mycology)
In mycology, a volva is a cup-like structure at the base of a mushroom that is a remnant of the universal veil, or the remains of the peridium that encloses the immature fruit bodies of gasteroid fungi. This macrofeature is important in wild mushroom identification because it is an easily observed, taxonomically significant feature that frequently signifies a member of Amanitaceae. This has particular importance due to the disproportionately high number of deadly poisonous species contained within that family. A mushroom's volva is often partially or completely buried in the ground, and therefore care must be taken to check for its presence when identifying mushrooms. Cutting or pulling mushrooms and attempting to identify them later without having noted this feature could be a fatal error.

Armillaria
''Armillaria'' is a genus of fungi that includes the '' A. mellea'' species known as honey fungi that live on trees and woody shrubs. It includes about 10 species formerly categorized summarily as ''A. mellea''. ''Armillarias'' are long-lived and form the largest living fungi in the world. The largest known organism (of the species ''Armillaria ostoyae'') covers more than in Oregon's Malheur National Forest and is estimated to be 2,500 years old. Some species of ''Armillaria'' display bioluminescence, resulting in foxfire. ''Armillaria'' can be a destructive forest pathogen. It causes "white rot" root disease (see Plant pathology section) of forests, which distinguishes it from ''Tricholoma'', a mycorrhizal (non-parasitic) genus. Because ''Armillaria'' is a facultative saprophyte, it also feeds on dead plant material, allowing it to kill its host, unlike parasites that must moderate their growth to avoid host death.

William Murrill
William Alphonso Murrill (October 13, 1869 – December 25, 1957) was an American mycologist, known for his contributions to the knowledge of the Agaricales and Polyporaceae. In 1904, he became the assistant Curator at the New York Botanical Garden (NYBG). He, along with the NYBG, founded the journal ''Mycologia'' and was its first editor for 16 years. Murrill was known to travel extensively to describe the mycota of Europe and the Americas. He traveled along the East Coast, Pacific Coast, Mexico and the Caribbean. Although Murrill was a very influential person at the NYBG, having worked his way up to become assistant director in 1908, his rather eccentric personality caused problems with his job. He went on annual collecting trips to Mexico, the Caribbean, Europe, and South America, sometimes, without informing any of his colleagues prior. These trips resulted in a cumulative total of 70,000 specimens, 1,400 of which are deposited in the NYBG.William Alphonso Murrill Records. ( ...
