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, six species, Cuphophyllus atlanticus (as C. canescens ), [1] C. colemannianus , C. flavipes , C. lacmus , C. lepidopus , and C. radiatus , are of global conservation concern and are listed as "vulnerable" on the IUCN Red List of Threatened Species. [2]
The genus was described by French mycologist Marcel Bon in 1985, [3] though it was subsequently synonymized with Hygrocybe by some authorities. [4] 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 species from which the genus takes its name. [5] This means that Camarophyllus sensu stricto is a synonym of Hygrophorus , since A. camarophyllus is a Hygrophorus species ( Hygrophorus camarophyllus ). This is now accepted by all standard authorities. [6] [7] [4] Singer (1951), however, proposed Agaricus pratensis (= Cuphophyllus pratensis ) as the type species of Camarophyllus, [8] which means that Camarophyllussensu Singer is a synonym of Cuphophyllus.
Recent molecular research, based on cladistic analysis of DNA sequences, indicates that Cuphophyllus is monophyletic and forms a natural group distinct from Hygrocybe sensu stricto. [9] [10] [11]
Species are distinguished from most other waxcaps by producing non-viscid, typically white, grey, or brownish basidiocarps (fruit bodies) often with decurrent lamellae (gills). Species of the genus Chromosera are superficially similar, though often more brightly coloured. [4]
In Europe, Cuphophyllus species are typically found in agriculturally unimproved, short-sward grasslands (including pastures and lawns). Elsewhere, they are most frequently found in woodland. The genus is cosmopolitan. [4]
Fruit bodies of one of the commoner European waxcap species, C. pratensis , are edible [4] and widely collected, sometimes being offered for sale in local markets.
