It's certainly no A. muscaria either... If you go to the library and look for a mycology book specific to your region, you may be able to identify it by making a spore print and examining it under a low power microscope. There's a broad unknown category too. Usually referred to as LBMs - little brown mushrooms, they're nondescript. Some are deadly, some might be edible. No way to easily determine this, 'cause they all pretty much look alike. Be careful, although you probably you needn't be as quite as careful as Sally suggests. We're talking about mushrooms not an unknown pathogen. I can't think of a single species that's so toxic as to harm you simply by handling it. The safety precautions I'd take are pick it gently, handle it lightly, wash your hands, keep it separate from any edibles (and other samples, to avoid spore cross-contamination), and if it's toxic dispose of it in a manner where it is inaccessible to both people and animals. There's a saying "Mushroom hunters are either old or bold, but not both..." Best of luck.

P.S. If you find such a book, it will probably tell which species are the kind (magic) you want to be looking for, and they'll be usually listed as "toxic" or "poisonous."
