Hygrocybe Citrinovirens
''Hygrocybe citrinovirens'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of Citrine Waxcap. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the species being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Taxonomy The species was first described from Denmark in 1923 by mycologist Jakob Emanuel Lange as ''Camarophyllus citrinovirens''. Julius Schäffer transferred it to the genus ''Hygrocybe'' in 1947. Recent molecular research, based on cladistic analysis of DNA sequences, has shown that ''Hygrocybe citrinovirens'' is distinct and belongs in ''Hygrocybe'' sensu stricto. Description Basidiocarps are agaricoid, up to 130mm (5 in) tall, the cap conical at first, retaining an acute or distinct umbo when expanded, up to 90mm (3 in) across, often splitting at the margins. The cap su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jakob Emanuel Lange
Jakob Emanuel Lange (2 April 1864 – 27 December 1941), was a Danish mycologist who studied the systematics of gilled mushrooms. His best-known work is ''Flora Agaricina Danica'', a five-volume plate work on the Agaricales of Denmark. He was also a dedicated Georgist land reformer. He was the father of Morten Lange (1919–2003), mycologist, professor at the University of Copenhagen and member of the Folketing The Folketing ( , ), also known as the Parliament of Denmark or the Danish Parliament in English, is the unicameral national legislature (parliament) of the Kingdom of Denmark — Denmark proper together with the Faroe Islands and Greenland.

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 (ring) or cortina) or ...

Hygrocybe
''Hygrocybe'' is a genus of agarics (gilled fungi) in the family Hygrophoraceae. Called waxcaps in English (sometimes waxy caps in North America), basidiocarps (fruit bodies) are often brightly coloured and have dry to waxy pileus (mycology), caps, white spores, and smooth, ringless stipe (mycology), stems. In Europe waxcaps are characteristic of old, unimproved grasslands (termed waxcap grasslands) which are a declining habitat, making many ''Hygrocybe'' species of conservation (biology), conservation concern. Four of these waxcap-grassland species, ''Hygrocybe citrinovirens'', ''Hygrocybe punicea, H. punicea'', ''Hygrocybe spadicea, H. spadicea'', and ''Hygrocybe splendidissima, H. splendidissima'', are assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Elsewhere waxcaps are more typically found in woodlands. Most are ground-dwelling and all are believed to be biotrophs. Around 150 species are recognized worldwide. Fruit bodies of severa ...

Fungi Of Europe
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 motility, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Mycological Society
The British Mycological Society is a learned society established in 1896 to promote the study of fungi. Formation The British Mycological Society (BMS) was formed by the combined efforts of two local societies: the Woolhope Naturalists' Field Club of Hereford and the Yorkshire Naturalists’ Union. The Curator of the Hereford Club, H. G. Bull, convinced the members in 1867 to undertake the particular study of mushrooms. While the mycological efforts of the Club diminished somewhat after Bull's death, the Union of Yorkshire founded its Mycological Committee in 1892. This Committee attracted the involvement of many eminent mycologists including George Edward Massee (1845–1917), James Needham (1849–1913), Charles Crossland (1844–1916), and Henry Thomas Soppitt (1843–1899). Mycologist Kathleen Sampson was a member for sixty years, as well as serving as president in 1938. The need for a national organisation and the need for a journal to publish their observations ...

Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups with ...

Waxcap Grassland
Waxcap grassland is short-wikt:sward, sward, nutrient-poor grassland that supports a rich assemblage of larger fungi, particularly waxcaps (species of ''Hygrocybe'' and related genera), characteristic of such habitats. Waxcap grasslands occur principally in Europe, where they are declining as a result of agricultural practices. The fungal species are consequently of conservation concern and efforts have been made in the United Kingdom and elsewhere to protect both the grasslands and their characteristic fungi. Over 20 species of European waxcap grassland fungi are assessed as globally "vulnerable" or "endangered" on the IUCN Red List of threatened species. Background The association of waxcaps with unimproved (nutrient-poor) grasslands was first noted in 1949 in the Netherlands, but current interest was stimulated by a series of papers published by Dutch mycologist Eef Arnolds in the 1980s. Arnolds not only confirmed the association of waxcaps with unimproved grasslands, but also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saprotrophic
Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (e.g. ''Mucor'') and with soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes. - "The word saprophyte and its derivatives, implying that a fungus is a plant, can be replaced by saprobe (σαπρός + βίος), which is without such implication." Saprotrophic plants or bacterial flora are called saprophytes ( ''sapro-'' 'rotten material' + ''-phyte'' 'plant'), although it is now believed that all plants previously thought to be saprotrophic are in fact parasites of microscopic fungi or of other plants. In fungi, the saprotrophic process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae. states the purpose of sap ...

Mycorrhizal
A mycorrhiza (; , mycorrhiza, or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, the plant root system and its surroundings. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry. In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi, or extracellularly as in ectomycorrhizal fungi. The association is normally mutualistic. In particular species, or in particular circumstances, mycorrhizae may have a parasitic association with host plants. Definition A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules by photosynthesis and supplies them to the fungus in the form of sugars or lipids, while the fungus supplies the plant with water and mineral nutrients, such as phosphorus, taken from the soil. Mycorrhiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hygrocybe Virescens
''Hygrocybe virescens'', commonly known as the lime-green waxy cap, is a species of agaric mushroom in the family Hygrophoraceae. The lime-green colored mushroom has a limited geographical distribution, having been reported only from California, Washington, and Mexico. Taxonomy The species was originally named ''Hygrophorus virescens'' by American mycologists Lexemuel Ray Hesler and Alexander H. Smith in their 1963 monograph of North American ''Hygrophorus'' species. In 2007, the species was transferred to the genus ''Hygrocybe''. Description The cap is wide, conical or convex when young, but becoming flat in maturity; the margin often curves up in age. The cap color can be variable: when young it is yellow with some orange, later becoming lime green. The cap surface is smooth, moist but not sticky, in age the margin becomes rimose (covered with a network of cracks and small crevices) and often splits into lobes. The context is lime green and very fragile. The odor and taste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
