NotesSmall delicate mushrooms, saprobic on wood. Cap conical (at least when young), spores white, gills not waxy (like the Hygrophorus-like mushrooms), fruiting bodies not reviving after drying (like the Marasmius-like mushrooms).
Some authors segregate Mycena into a number of genera, some of which have been used in the New Zealand literature. These genera are based on characters such as the presence and absence of cheilocystidia, of latex in the tissue, of gelatinous caps and/or stipes, spore shape, etc. The genera include Basisopus, Collopus, Galactopus, Insiticia, Prunulus, and Mycenula.
Thirty or more species of Mycena sensu stricto have been reported from New Zealand, only those listed below have descriptions or images available from NZFungi.
