This mushroom is found throughout North America from late June to early November. It is found on the ground in mixed woods, or in the grass near trees. They especially flourish in decayed bark of broadleaf trees. Our Amanitas are found about six feet from a large Oak tree in our yard, with roots that stretch out to the area where we've removed the mushrooms. They are usually found alone or in a small, scattered group.
Young mushrooms resemble varieties of edible mushrooms before the cap expands.
There are several look-a likes which are safe. Conversely, there are other varieties of Amanitas, including the Death Cap, that vary somewhat in looks but are as deadly as the Destroying Angel. I have also received follow-ups from those who did find these deadly mushrooms in their yards and removed them before another life was lost. I know, though, that there is a greater reason for losing Rory. It overwhelms me to think of the lives she has saved.
