Sharon, sorry to hear that you ate the ringless ones (and got sick).
When I was young, my mother would take me into the woods every September to look for the honey mushrooms, Armillaria Mellea. This was the
mushroom that she learned from her own mother to pick.
It grows out of dead wood, so it's common around stumps and old fallen branches with a lot of decay. She would look for that telltale ring around the stem and also would smell the mushroom.
After cleaning, she'd sautee the mushrooms in butter with onions, then add sour cream. The dish would top some boiled potatoes. Dang they were good, even better than morels. I miss those honey mushrooms. They don't grow around Oklahoma.
