The cap is 4-8 cm diameter with neatly rolled edges. The cap and stipe colour are dark, purple-brown at first. The fungus dries paler. The middle of the cap is deeply depressed. It looks like a little goblet.  The stem is covered in fine whitish fibrills. 

The gills are decurrent and forked at the edges. The slightly scaly brown stipe is long in comparison with the cap diameter. The stipe base is slightly swollen and has obvious white hairs covering it. Spores are almost white.

Photograph from top down, in side view and from underneath to show gills and full length of stipe.  Note habitat and substrate.

Mainly deciduous woodland. It favours mossy logs and tree bases.
