For better results with mushroom identification in the future, try to get photos of the underside and stipe of mushrooms. The more pics the better chances of ID. Providing a rough location can also be beneficial. From what I can tell this mushroom is likely some type of oyster mushroom (Pleurotus sp) or maybe a flat crep (Crepidotus applanatus)

Looks great! I see some hedgehogs, and chanterelles, is that amethyst deceiver on the right?

Check out Gremolata and/or Pangrattato. It's a Mediterranean herb and bread crumb crumble with lemon zest. Sounds like what you're looking for. You can always mold the recipe to your own taste with different herbs.
