Oddly peculiar fungi

Another photo from Little Britain. I've put this up because these are the most peculiar fungi I've ever seen. They are darker than they appear in the shot. Anyone know anything about them?

Weird. Are they hard?

@bigsusan55 I don't know, I didn't like to touch them! If you look at the one on the right on the top line, it looks as if they might explode like puffball mushrooms.

Certainly wierd! I thought they were more snails 'til I clicked to enlarge! lol
