I do believe this mushroom is found on Long Island, NY. I have eaten them from my lawn, and also seen them on the edges of Oak and Beech forests here on the South Fork. They are delicious.

I just checked and it is now listed in the Long Island Mycological Club records. The change has been made. Thanks for the heads-up.
