I noticed large numbers of these mushrooms growing in leaf litter in the woods just outside Prague, Czech Republic. The smaller button shaped ones are probably (but not definitely) the younger ones as they seemed to be growing together.
There were also several piles of just the stems with the caps cleanly sliced off so I assume someone has been foraging them recently. The Czechs are very much into their wild mushrooms but there was no one around today that I could ask so wondered if someone could identify these for me (don't worry, I'm not going to try and eat them off the back of an internet ID, I'm just interested).

Cheers for your help :)
