It would be hard to say imo exactly what tree or trees the mushroom is associated with. Honey fungus is know as the "humungous fungus" because it's mycelium covers a very large area. As to whether or not you should eat them, try a little bit, don't over do it. After a few hrs or if you wanted to wait a day, suffer no ill effects, I would say they are good. Be careful though and make sure you cook them well. Imo ringed honeys are a lot tastier. I find ringless to be bitter sometimes and needs to be parboiled to remove the bitterness. Good luck!
