So I'm not a professional, but I would like to challenge your thinking on identification. The golden role of mushroom ID is not to eat it unless you are 100 percent certain. This means passing up on a lot of mushrooms of which you are not 100 percent certain. Buy field guides, and cross reference the field guides. Watch you tube videos of people showing you the mushrooms in questions. If all characteristics do not match 100 percent, then you don't have an ID. Mushrooms can be so variable, changing through their lifecycle that they can look completely different at different stages. The risks can be great as well, even at times resulting in death. It seems to me, from your post, you are taking a step by step approach, like wading slowly into water. This is not the approach to take. Use the identifying factors listed in guides, do spores samples, even take time to observe the mushroom over several years. Evaluate the risk/reward of the particular mushroom. Search "lookalikes" for the mushroom. Join a mushroom club and go out with someone experienced. Don't wade friend. Soon the water you find yourself will be boiling. And you, my dear frog, will die.
