Reddog- Rarely...maybe? I've only heard of anyone finding them in pines a time or two, and not very many at that. Your better off in river/creek bottoms with lots of elm, ash, maple, and oak trees.
Piggy- If you have access to some fresh portabello mushrooms like in grocery stores you can fix them the same way and they are real good, not as good as wild morels but a close second. Slice in 1/4" strips, dip in raw scrambled egg, flour them, and fry in a deep fryer or skillet with an inch of oil until golden brown, salt lightly after they come out.
$bowhunter$- The true white or grey morels that look like the picture that Caleb Andes just posted are harmless and extremely tasty. You should try some and if your not sure what you got then post a pic of them here and we will help identify. You don't know what your missing.
Just don't pic anything that doesn't look exactly like the pics Caleb posted, with the exception that they can vary in color from grey, to white, to kinda like a vanilla blonde or yellowish color. The unmistakeable texture and shape of the cap is the only identification you need. You can also get a book on wild mushrooms and carry with you when you hunt. My state Conservation department offers them to residents for free. You should call your Conservation department and see if they have such a free publication as well, I bet they do or at least something for a small fee.
