The sections of Mycena

Maas Geesteranus (1992) divided the genus into 38 sections and provided keys to each section comprising all the species of the Northern Hemisphere. Since then many new species have been discovered, and a number of new sections have been proposed. At the present web site the visitor will find new keys to the sections with all the European species.

Most sections of Mycena are not truly homogeneous. Practically always, one or more species appear to have deviating characters. Or specimens may change so much in the course of their development as to make some of their characters applicable only during a limited period. Because of the heterogeneousness of the genus a number of the sections comprises only one species.

The sections are:
