mushroom identification?

Normally, I’d post this on Facebook and get quick answers from several friends in-the-know. I’m continuing my experiment with returning to my personal site rather than leaning so heavily on Facebook, so I’ll post it here and see what happens…
These mushrooms were growing in the leaf-filled crevice on the edge of my asparagus bed. Are they edible?
(I won’t eat them until I’m *sure,* of course!)
