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 1879 ...

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.

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.

Decurrent
''Decurrent'' (sometimes decurring) is a term used in botany and mycology to describe plant or fungal parts that extend downward. In botany, the term is most often applied to leaf blades that partly wrap or have wings around the stem or petiole and extend down along the stem. A "decurrent branching habit" is a plant form common for shrubs and most angiosperm trees, contrasted with the excurrent or "cone-shaped crown" common among many gymnosperms. The decurrent habit is characterized by having weak apical dominance that eventually produces a rounded or spreading tree crown. Examples of trees with decurrent habit are most hardwood trees: oak, hickory, maple, etc.Claud L. Brown, Robert G. McAlpine, Paul P. Kormanik, "Apical Dominance and Form in Woody Plants: A Reappraisal", ''American Journal of Botany'', Vol. 54, No. 2 (February 1967), pp. 153–162, In mycology, the term is most often applied to the hymenophore of a basidiocarp (such as the lamellae or "gills" of a mus ...

Günther Beck Von Mannagetta Und Lerchenau
Günther Ritter Beck von Mannagetta und Lerchenau (25 August 1856 in Pressburg, modern Bratislava – 23 June 1931 in Prague) was a prominent Austrian botanist. Life Ritter Beck-Mannagetta, son of a state prosecutor, studied at the University of Vienna, where he graduated as Dr. phil. in 1878. After a period working as a volunteer at the ''Botanisches Hofkabinett'', (later the Natural History Museum), he became head of the Botanical Department there from 1885 to 1899. In 1894 he became assistant professor, and in 1895 associate professor at the University of Vienna. From 1899 to 1921 he was professor of systematic botany at the German Charles University in Prague and head of the Botanical Garden there. His main interests were plant geography and the flora of the Alps and the Balkans. Beck also revised the pitcher plant genus '' Nepenthes'' in his 1895 monograph, " Die Gattung ''Nepenthes''".

Rolf Singer
Rolf Singer (June 23, 1906 – January 18, 1994) was a German-born mycologist and one of the most important taxonomists of gilled mushrooms (agarics) in the 20th century. After receiving his Ph.D. at the University of Vienna in 1931 he worked in Munich. By 1933, however, Singer left Germany for Vienna due to the political deterioration in Germany. There he met his wife, Martha Singer. From Vienna, Singer and his wife went to Barcelona, Spain, where Singer was appointed assistant professor at the Autonomous University of Barcelona. Persecution by the Spanish authorities on behalf of the German government forced Singer to leave Spain for France in 1934. After a fellowship at the Museum d'Histoire Naturelle in Paris, Singer again moved, this time to Leningrad, where he was Senior Scientific Expert at the Botanical Garden of the Academy of Sciences of the USSR. During his time at the Academy, Singer made many expeditions to Siberia, the Altai Mountains, and Karelia. In 1941, Sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trama (mycology)
In mycology, the term trama is used in two ways. In the broad sense, it is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue that is commonly referred to as the "flesh" of mushrooms and similar fungi.Largent D, Johnson D, Watling R. 1977. ''How to Identify Mushrooms to Genus III: Microscopic Features''. Arcata, CA: Mad River Press. . pp. 60–70. The second use is more specific, and refers to the "hymenophoral trama" that supports the hymenium. It is similarly interior, connective tissue, but it is more specifically the central layer of hyphae running from the underside of the mushroom cap to the lamella or gill, upon which the hymenium rests. Various types have been classified by their structure, including trametoid, cantharelloid, boletoid, and agaricoid, with agaricoid t ...
