[Nettle Runner]

Clumber Park (33) 21 Oct 2007



Cap dia 20mm (largest sp)
Stem 40mm
Gills White

It is the stem colour that has me confused. I had thought it might be White milking bonnet. Unfortunately I didn't get the base of the stem in the pics to see iif it had the cottony fibres.

Your comments and observations welcomed

Did you break a stem? Although Mycena galopus does not grow on wood, M. haematopus does, and would have bled red sap on breaking the stem. They do look like slightly dry specimens. Another very common Mycena growing as per your specimens is M. arcangeliana. It has grey stems, and a cap which is variously grey, white or yellowish. Put some specimens in a small box, and leave for an hour or few, and you will smell iodoform.
