Hi Amanda
Well, I'm going to come clean and admit to skulking about at the back of the crowd hoping some one else would take up the challenge, but here goes; the results of more than a happy hour of internet and book trawling (purely for interest, one book contains 1751 illustrations and over 3,000 references. Unfortunately the foreword states it doesn't represent all species growing in Europe...aaarrrggghhh

) so apologies in advance for any discrepancies. Also, the wood chips might be throwing up confusing growing conditions (type of wood etc or the mycelium could be already in the ground).
Top, genus Mycena possibly Sepia

Next, Coprinus Micaceus

Orange one, Hygrocybe Strangulata

This one bugs me, Hygrocybe Strangulata is uncommon and should be growing in grass so possibly incorrect.
Bottom, genus Pluteus possibly Primus or Podospileus. Sorry about the silly long link, once there you'll have to scroll down to see the pics

I'm guessing you'd like to know if they pose a threat to the kiddies. Apart from they could cause loss of traction to to a fast-cornering child, providing my identifications are correct these fungus shouldn't present any particular dangers. I'm not saying they're edible and as always should be treated with the same respect as any other wild plant.
Hope this helps
Kind regards
Martin
