Clump of fungi
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
I do not think these are Earth Balls (and they are certainly not Earth Stars - see http://www.ispot.org.uk/node/10767 ) because they do not have the warty skin of that species. It looks like a puffball of some kind to me, but someone more expert than me will no doubt be able to tell you more.

I agree with Jonathan.
One specimen in the top-right of the image shows a distinct stem. These are most-likely to be Common Puffball Lycoperdon perlatum, but they are badly weathered and it is probably only safe to call them Lycoperdon sp.
Could they possibly be Peziza Vesiculosa? I agree they are nort Earth Stars.
I am also no expert but my instinct would also be puff balls.
