Wild Shroom

I found this fair-sized mushroom in a shady corner of our garden today. My camera was on the wrong setting entirely, and I then noticed and adjusted it (well, I put it back on automatic, where is usually is!), but after taking a look at the shots, I preferred this one, in the wrong setting. It looks like a normal mushroom, the kind that I buy from the supermarket, but I just couldn't bring myself to eat it - I have that little faith in my own judgement!
