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 ...

Cuphophyllus Lacmus
''Cuphophyllus lacmus'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of grey 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 1803 by naturalist Heinrich Schumacher as ''Agaricus lacmus''. It was transferred to the genus ''Cuphophyllus'' by the French mycologist Marcel Bon in 1985. Recent molecular research, based on cladistic analysis of DNA sequences, has confirmed that ''Cuphophyllus lacmus'' is a distinct species, but within a group (including '' Cuphophyllus subviolaceus'') that requires further research. Description Basidiocarps are agaricoid, up to 70mm (5 in) tall, the cap hemispherical at first, becoming broadly convex to flat when expanded, u ...

Cuphophyllus Colemannianus
''Cuphophyllus colemannianus'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of toasted 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 Britain in 1854 by naturalist Andrew Bloxam as ''Hygrophorus colemannianus''. It was transferred to the genus ''Cuphophyllus'' by the French mycologist Marcel Bon in 1985. Recent molecular research, based on cladistic analysis of DNA sequences, has confirmed that ''Cuphophyllus colemannianus'' is a distinct species. Description Basidiocarps are agaricoid, up to 50mm (5 in) tall, the cap hemispherical at first, becoming broadly convex to flat when expanded, up to 50mm (3 in) across. The cap surface is smooth, slightly greasy ...

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. ...

Cuphophyllus Canescens
''Cuphophyllus canescens'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae, known from North America. In its wide sense (including the recently separated '' C. atlanticus'') it has been assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Taxonomy The species was first described from North Carolina in 1942 by American mycologists Alexander H. Smith and Lexemuel Ray Hesler as ''Hygrophorus canescens''. It was transferred to the genus ''Cuphophyllus'' by French mycologist Marcel Bon in 1990, at which time it was thought also to occur in northern Europe. As a result of molecular research, based on cladistic analysis of DNA sequences, ''Cuphophyllus canescens'' has, however, been found to be restricted to North America. Similar species ''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 ...

Cuphophyllus Lepidopus
''Cuphophyllus lepidopus'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of scalyfoot 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 England in 1927 by mycologist Carleton Rea as ''Hygrophorus lepidopus''. It was known only by an illustration of Rea's collection until rediscovered in England in 2004. It was then considered a variety of ''Hygrocybe fornicata'', but subsequent molecular research, based on cladistic analysis of DNA sequences, has indicated that ''Cuphophyllus lepidopus'' is a distinct species. Description Basidiocarps are agaricoid, up to 100mm (4 in) tall, the cap broadly conical at first, becoming broadly convex when expanded, up to 75mm (3 in ...

Hygrocybe Pratensis
''Cuphophyllus pratensis'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of meadow waxcap in the UK and in North America has variously been called the meadow waxy cap, salmon waxy cap, and butter meadowcap. The species has a widespread, mainly temperate distribution, occurring in grassland in Europe and in woodland elsewhere. The basidiocarps (fruit bodies) are edible and are occasionally collected and sold commercially. Taxonomy The species was first described in 1774 by the German mycologist and naturalist Jacob Christian Schäffer as ''Agaricus pratensis''. It was subsequently combined in a number of different genera, before being transferred to ''Hygrocybe'' in 1914. The specific epithet comes from Latin "pratensis" (= growing in meadows). Molecular research, based on cladistic analysis of DNA sequences, has found that ''Hygrocybe pratensis'' does not belong in ''Hygrocybe'' ''sensu stricto'' but to the ge ...

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 ...

Hygrophoraceae
The Hygrophoraceae are a family of fungi in the order Agaricales. Originally conceived as containing white-spored, thick-gilled agarics (gilled mushrooms), including ''Hygrophorus'' and ''Hygrocybe'' species (the waxcaps or waxy caps), DNA evidence has extended the limits of the family, so it now contains not only agarics, but also basidiolichens and corticioid fungi. Species are thus diverse and are variously ectomycorrhizal, lichenized, associated with mosses, or saprotrophic. The family contains 25 genera and over 600 species. None is of any great economic importance, though fruit bodies of some ''Hygrocybe'' and ''Hygrophorus'' species are considered edible and may be collected for sale in local markets. Taxonomy History The family Hygrophoraceae was first proposed by Dutch botanist Johannes Paulus Lotsy (1907) to accommodate agarics with thick, waxy lamellae (gills) and white spores. Lotsy's concept of the family included not only the waxcap-related genera ''Hygrophorus'', ...

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 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 firs ...

Hygrophorus
''Hygrophorus'' is a genus of agarics (gilled mushrooms) in the family Hygrophoraceae. Called "woodwaxes" in the UK or "waxy caps" (together with ''Hygrocybe'' species) in North America, basidiocarps (fruit bodies) are typically fleshy, often with slimy caps and lamellae that are broadly attached to decurrent. All species are ground-dwelling and ectomycorrhizal (forming an association with living trees) and are typically found in woodland. Around 100 species are recognized worldwide. Fruit bodies of several species are considered edible and are sometimes offered for sale in local markets. Taxonomy History ''Hygrophorus'' was first published in 1836 by Swedish mycologist Elias Magnus Fries. The generic name is derived from the Greek ῦγρὁς (= moist) + φόρος (= bearer), with reference to the slimy caps found in many species. Fries (1849) subsequently split the genus into three subgenera: ''Limacium'', ''Camarophyllus'', and ''Hygrocybe''. The last of these is now recogn ...

Marinus Anton Donk
Marinus Anton Donk (14 August 1908 – 2 September 1972) was a Dutch mycologist. He specialized in the taxonomy and nomenclature of mushrooms. Rolf Singer wrote in his obituary that he was "one of the most outstanding figures of contemporary mycology." Early life Donk was born in Situbondo, East Java in 1908, and completed secondary school in The Hague, Netherlands. He studied biology at the University of Utrecht, starting in 1927. As a graduate student in mycology he completed the work for his 1931 "Revisie van de Nederlandse Heterobasidiomyceteae" (Revision of the Dutch Heterobasidiomycetes). He completed his studies and attained a doctorate degree in 1933 with the second part of his work, ''Revisie van de Nederlandse Heterobasidiomyceteae II''. Afterwards he returned to Java, where he worked from 1934 to 1940 as a teacher, and, starting from 1941 as a curator in the herbarium of the Buitenzorg Botanical Garden. He was interned in a Japanese prison camp from 1942 to 1945. Du ...

Cladistic
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...
