Crepidotus

I was really pleased to find these tiny (about 6mm across) Crepidotus fungi this morning, growing on a piece of dead gorse. The cap is a smooth white kidney shape while underneath the gills fan out a bit like coral. As they age the gills turn a light brown colour. There are a number of Crepidouts species, they all look very similar, but I suspect this is Crepidotus variabilis which is the more common.
