Not recognized as a Mycena by Maas Geesteranus (1992). Rexer (1994) transferred it to the new genus Roridomyces.

Among needles and vegetable debris under both coniferous and deciduous trees. Widely distributed in Norway.

Miersch & Dänchke (2007) proposed the new species Mycena palmensis that was collected in the Canarian Island La Palma, Spain, and characterized by the almost entirely white fruitbodies and pyriform, verrucose cheilocystidia.

Rexer (1994) described another new species, R. appendiculatus.
