[3] Molecular research, based on cladistic analysis of DNA sequences, has, however, shown that it does not belong in Hygrocybe sensu stricto.

Instead, the species has been moved into the related but separate genus Neohygrocybe, as already proposed on morphological grounds by Czech mycologist Josef Herink in 1958.

When cut, the whitish flesh turns slowly reddish brown and has a slightly chemical smell.

[6] Neohygrocybe ingrata is typical of waxcap grasslands, a declining habitat due to changing agricultural practices.

[1] The species is included in national Red Lists of 13 European countries[1] and is regarded as (critically) endangered in Croatia, Czech Republic, Denmark, Finland, France, Germany, Lithuania, Poland, and Switzerland.
