Humidicutis is one of the wax-gill mushrooms, a group of small, brightly-coloured, saprobic, soil-inhabiting fungi which have brittle flesh with a waxy feel when crushed between the fingers. The main genera of wax-gills are Hygrophorus, Humidicutis, Hygrocybe and Gliophorus. Gliophorus is recognised by the thick glutinous coating over the surface, the caps of Humidicutis are typically characteristically deeply split at the sides, the other genera distinguished on the basis of microscopic features of hyphae in the gills and the cap. Gills broadly attached to stalk, no ring on stalk. Spore print white.

There are 5 species ofHumidicutis reported from New Zealand, 3 of which are endemic.
