If you have a place near you that can identify mushrooms, I'd take some to get identified if you get a chance. You might have to do some calling around, we had trouble finding a person who could identify ours. (Well, no, we didn't - we went to the right place but they told us nobody there could do it... but they were mistaken. *facepalm*)
They're probably fine, but I'd get 'em ID'd if you have the chance, just for peace of mind later. =>
