they all look like field mushroom just at different stages of development. having said that it is also difficult to tell from just a photo. if in doubt do not eat them.

We don't have a mycologist on the site, and I don't think any of the rest of us is equipped to definitively say that these are edible mushrooms, particularly not without being able to see, touch and smell them, sorry.

I agree with Bamboo, it would be irresponsible for us to comment on these pictures. I do have my own opinion of them but there could be something that I am not aware of. Do you have a staffed RSPB, Wildlife Trust or similar site near you? If so, take them along and ask an experienced person.

Agree with Bulba. Don't gamble with your life. One wrong bite could be disastrous and no medic can help you.

I agree, field mushrooms, unless they bruise yellow when cut. However whether you risk it nor not is entirely down to you. If you look on line for the Surrey Fungus Group someone there would be able to confirm it for you. Or not!
