These mushrooms have a dark grey-brown cap which is lighter around the margin. The gills are creamy-pale grey when young becoming cream when older with a sinuate attachment to the stipe. The stipe is light grey and fibrous in appearance and 4-5 mm in diameter and tapers at the base. The caps were observed growing from 1.1 to 2.6 cm in diameter and up to 3.5 cm in height.
