With a cap just 5 to 15 mm in diameter, these small fungi belonging to the species Mycena amicta (Mycenaceae), sometimes have a striking olivaceous, greenish or bluish green shade. The base of the stipe usually is somewhat blue-green, but sometimes it can be entirely blue.
The species grows solitary, scattered, to occasionally clustered on conifer logs (often under the bark) in montane regions of North America and Europe.
