Nature’s Pop-ups

These mushrooms weren’t there yesterday, but they’re here today. They’re one of nature’s own pop-ups.

I’m opening comments on this post in the hope that readers with mycological expertise will identify this fungus. It looks a little bit like Agaricus campestris, which is edible. But then again it also might be Amanita phalloides, the death cap mushroom. I left it alone!
