The American Caesar's Mushroom (Amanita caesarea) is also known as Caesar's Amanita.
At first glance its distinguishing characteristics are:
This species inhabits dry, oak-pine woodlands from late July through October. Although not poisonous, American varieties of the Caesar's Amanita are not recommended to amateurs as edible.
In fact, no mushroom should be eaten without the advice of an expert. Our well-known Fly Agaric has no radially lined margins around the cap and has whitish gills. A close inspection should easily allow identification of either of these similar mushrooms that are members of the dangerous genus Amanita.
