Gloioxanthomyces Vitellinus
''Gloioxanthomyces vitellinus'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of Glistening Waxcap. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the Glistening Waxcap being assessed as globally "endangered" on the IUCN Red List of Threatened Species. Taxonomy The species was first described by Swedish mycologist Elias Magnus Fries in 1863 as ''Hygrophorus vitellinus''. Finnish mycologist Petter Adolf Karsten transferred it to the genus ''Hygrocybe'' in 1879. Recent molecular research, based on cladistic analysis of DNA sequences, has shown that the species is not closely related to the type of ''Hygrocybe'', but belongs in the related genus ''Gloioxanthomyces''. Description Basidiocarps are agaricoid, up to 50 mm (2 in) tall, the cap hemispherical, up to 20 mm (1 in) across. The cap surface is ...

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ... [...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, Dr. 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 Dr. 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 observatio ...

Waxcap Grassland
Waxcap grassland is short-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 noted the ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromosera Citrinopallida
''Chromosera'' is a genus of fungi in the family Hygrophoraceae. Within the family Hygrophoraceae it is closely related to the genus ''Gloioxanthomyces''. It contains five species. The generic name honors the mycologist Meinhard Moser, and also alludes (''chromos'') to the distinct coloration of the mushrooms, by overlapping 'chromos' with 'Moser', hence ''Chromosera''.

Hygrocybe Ceracea
''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 caps, white spores, and smooth, ringless stems. In Europe they are characteristic of old, unimproved grasslands (termed waxcap grasslands) which are a declining habitat, making many ''Hygrocybe'' species of conservation concern. Four of these waxcap-grassland species, ''Hygrocybe citrinovirens'', '' H. punicea'', '' H. spadicea'', and '' 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 several ''Hygrocybe'' species are considered edible and are sometimes offered for sale in local markets. Taxonomy History ''Hygrocybe'' was fir ...

Gloioxanthomyces Nitidus
''Gloioxanthomyces nitidus'', commonly known as the shining waxcap, is a species of fungus in the family Hygrophoraceae. It was originally described by Miles Berkeley and Moses Ashley Curtis in 1853 as a species of ''Hygrophorus''. The specific epithet ''nitidus'' means "shining". It was one of two species transferred to the newly created genus ''Gloioxanthomyces'' in 2013. Fruitbodies have convex, apricot-yellow to orange caps that are in diameter. The pale yellow, waxy gills are decurrent, with a somewhat distant spacing. Other than the gills and the base of the stipe, the bright coloring of the fruitbody fades with age. Spores are elliptical, smooth, and measure 6–10 by 4–6 µm. It is found in North America, where it grows on the ground (often among mosses) in groups in coniferous or mixed forest Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and wi ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inamyloid
In mycology a tissue or feature is said to be amyloid if it has a positive amyloid reaction when subjected to a crude chemical test using iodine as an ingredient of either Melzer's reagent or Lugol's solution, producing a blue to blue-black staining. The term "amyloid" is derived from the Latin ''amyloideus'' ("starch-like"). It refers to the fact that starch gives a similar reaction, also called an amyloid reaction. The test can be on microscopic features, such as spore walls or hyphal walls, or the apical apparatus or entire ascus wall of an ascus, or be a macroscopic reaction on tissue where a drop of the reagent is applied. Negative reactions, called inamyloid or nonamyloid, are for structures that remain pale yellow-brown or clear. A reaction producing a deep reddish to reddish-brown staining is either termed a dextrinoid reaction (pseudoamyloid is a synonym) or a hemiamyloid reaction. Melzer's reagent reactions Hemiamyloidity Hemiamyloidity in mycology refers to a special ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guide A field guide is a book designed to help the reader identify wildlife (flora or fauna) or other objects of natural occurrence (e.g. rocks and minerals).

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 ...
