The most common killer mushrooms—white Amanitas called "death caps" (Amanita phalloides)—are not common is most urban areas. Nonetheless, they do grow in some cities. This mushroom could be confused with them. So be careful.

Incidentally, imagine how the smooth lepiota feels, looking like a death cap. How would you feel if you looked like a deadly white Amanita? No one would pick or taste you. Everyone would kick you.
