The genus Mycena has been studied by many mycologists during the years, e.g. the Danish mycologist J. E. Lange, the French mycologist R. Kühner, A. H. Smith in the USA, and the Dutch mycologist R. A. Maas Geesteranus. The most recent account is the work by Giovanni Robich from Italy.

The work by Dr. Maas Geesteranus inspired and motivated professionals as well as amateurs to study Mycenas, and the recent years quite a few new species have been described, many of which have never been illustrated. On this site some of these species are shown for the first time.

As an incitement to get more people interested in Mycenas I have made a provisional identification key to the Norwegian species of Mycena with photographs and descriptions of each species. The key also provides information about habitats and the occurence in Norway.

So far just above 100 species of Mycena have been recorded in Norway. The complete list of these species may be a good starting point to get to know the Norwegian Mycenas.

The sections of Mycena

Mycena d'Europa by Giovanni Robich (2003) presents 143 members of the genus Mycena, comprising 117 species and 26 varieties or forms, of which 8 are new species. All taxa are shown in colour photos accompanied by microscopic drawings.

In Funga Nordica (2008) there are comprehensive keys and descriptions of 104 species of Mycena. The descriptions are accompanied by drawings of a number of microscopic structures.
