Here's what they look like before washing:
Here below is proof positive of inky caps. The water you soak them in turns to ink!
I soaked the mushrooms in salt water to rid them of the inhabitants.
Now here they are in the fry pan with butter, saute for 20 min.

For more information on foraging safely check out "Wildman" Steve Brill. He has a lovely vegetarian cookbook out. He was once arrested for eating a dandelion, and gives tours in parks to anyone who wishes to know how to forage. He's quite a character, having been interviewed by everyone from Al Roker (twice) to David Letterman.
