Any ideas on this one? Initially looked like rather a large grey mycena, note the card is not all the way down to the ground. however gills looked to be rather grey and in the field appeared to be mottled (suggesting something other than mycena) but looking at the photo it does not show this so i could have been mistaken in the field in the bright sun.
growing in grassland well away from trees although well manured patch as i discovered when i put my rucksack down.
