How about a mushroom foraging kit? You could include a guide book on identifying and cooking mushrooms, as well as a basket for collecting them. You could also include a gift certificate for a mushroom hunting tour, a weekend camping trip in a nearby forest, or a cooking class focused on mushroom cuisine. If you want to give a physical gift, you could consider a mushroom growing kit, which would allow your son to grow his own mushrooms at home.
Or you can get him a star map with an important date you share.
