Generally an edible mushroom that normally grows on a tree needs to be growing on oak. For instance, if you do find an edible mushroom like hen of the woods, it needs to be growing on oak to still be edible. I would love to get more into mushroom hunting, but the safest way is to go foraging with a pro. However, there are, IIRC, around 5 edible mushrooms that are easy to identify and do not have a poisonous identical look-alike, but one must be able to understand more than just what color it is.
I do have a hen of the woods dehydrated and packed into jars. At my in-laws, there is a chicken of the woods, but someone else always snags it before we get there! I have also harvested and eaten chanterelles and morels.
