Cuphophyllus Atlanticus
''Cuphophyllus atlanticus'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. Until recently (2021), the species was considered to be conspecific with the North American '' Cuphophyllus canescens'', but DNA sequencing has shown that it is distinct. As ''C. canescens'', it has been given the recommended English name of felted waxcap in the United Kingdom. ''Cuphophyllus atlanticus'' has a European and North American distribution, occurring in Europe mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in ''C. canescens'' (including ''C. atlanticus'') being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Taxonomy The species was first described from Norway in 2021 as a result of molecular research, based on cladistic analysis of DNA sequences. Previously, European specimens had been referred to the similar '' Cuphophyllus canescens'', but the latter species appears to be confined to North America. ...

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 ...

It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. Method A spore print is made by placing the spore-producing surface flat on a sheet of dark and white paper or on a sheet of clear, stiff plastic, which facilitates moving the spore print to a darker or lighter surface for improved contrast; for example, it ...

Fungi Of Europe
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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 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 gro ...

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 ...

Sensu Lato
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning ...

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 ...

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 (for example ''Mucor'') and soil bacteria. Saprotrophic microscopic fungi are sometimes called saprobes; 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 other plants. The 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 saprotrophs and their internal nutrition, as well as the main two types of fungi that are most often referred to, as well as describes, visually, the process of saprotrophic nutrition through a diagram of hyph ...

Mycorrhizal
  A mycorrhiza (from Greek μύκης ', "fungus", and ῥίζα ', "root"; pl. mycorrhizae, 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, its root system. 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 (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is sometimes 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 such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, such as phos ...

Cuphophyllus
''Cuphophyllus'' is a genus of agaric fungi in the family Hygrophoraceae. ''Cuphophyllus'' species belong to a group known as waxcaps in English, sometimes also waxy caps in North America or waxgills in New Zealand. In Europe, ''Cuphophyllus'' species are typical of waxcap grasslands, a declining habitat due to changing agricultural practices. As a result, four species, '' Cuphophyllus atlanticus'' (as '' C. canescens''), '' C. colemannianus'', '' C. lacmus'', and '' C. lepidopus'' are of global conservation concern and are listed as "vulnerable" on the IUCN Red List of Threatened Species. Taxonomy History The genus was described by French mycologist Marcel Bon in 1985, though it was subsequently synonymized with ''Hygrocybe'' by some authorities. ''Cuphophyllus'' species have sometimes been referred to the genus ''Camarophyllus'' ( Fr.) P.Kumm., but, as argued by Donk (1962), the type species of ''Camarophyllus'' must be ''Agaricus camarophyllus'' Alb. & Schwein. the speci ...

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 ...

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 ...
