Another Pinkgill - the Indigo Pinkgill

This one is not a new species as I found it in the West Field last year. This year it is to be found in both the West Field (in a different place) and the South Field. As I was doing the ID and gradually homing in on Entoloma chalybeum I noticed a brown edge to the gills on one of the specimens which I had not previously realised was a feature sometimes seen on this species.
