Those are honey mushrooms, armillaria mellea. Locally people call them buttons. Its a species constellation...locally there are 3 or 4 similar species...A. mellea, A. gallica are the two most common.
They are safe to eat well cooked. Armillaria and allies have a pretty high amount of chitin...which is just a hard to digest protein. So cook them thoroughly.
If youre finding those...look for Entoloma and the abortive variant. Entoloma abortivum. The latter is edible and tastes a lot like shrimp.
Armillaria and Entoloma literally go to war over the same habitat and often you will find all three fruiting on the same tree together. It is Armillaria that seems to win...out competing Entoloma for habitat and invading its mycelium causing celullar disruotikn and ultimately causing Entoloma primordia to abort.
