A great idea could be a mushroom hunting kit that you put together yourself. Here are some items you could include:
1. A guidebook on mushroom identification
2. A basket or tote bag for collecting mushrooms
3. A foraging knife for cutting the mushrooms
4. A handheld magnifying glass for closer inspection of the mushrooms
5. A waterproof map of local mushroom hunting areas
6. A compass or GPS device for navigation
7. A subscription to a mushroom hunting or foraging magazine
8. A gift card to a local outdoor gear store or mushroom farm/shop.
You could also consider booking a guided mushroom hunting experience for the two of you, or plan a weekend getaway to a location known for its mushroom hunting.
Or you can get him a star map with an important date you share.
