 Recent molecular research, based on cladistic analysis of DNA sequences, suggests that "Cuphophyllus" is monophyletic and forms a natural group distinct from "Hygrocybe" sensu stricto.It is therefore likely to be adopted more widely in the near future, as noted in the most recent (2010) European guide to waxcaps.Species are distinguished from most other waxcaps by producing basidiocarps (fruit bodies) with strongly decurrent lamellae (gills).
