A species of woodland edge and hedgerows, but also found with garden mulch. Most British records are from England and Wales with a few in Scotland. This would appear to be the first Outer Hebridean record. The cap rarely exceeds 35 mm and variable in colour, usually with bronzy-brown in the mix but can also be quite reddish. The gills are adnate with a decurrent tooth. The common name is a little misleading as the reddish gill-edge is often lacking. The stipe is pale with a rooting pseudorhiza. Spores are reddish-brown, and cystidia mainly lageniform in shape. Gill-face cystidia (pleurocystidia) are sparse. Those on the stipe are common especially towards the apex and usually bunched.
