How about a mushroom hunting kit? It could include a mushroom knife, a field guide to help identify different varieties, and a woven basket to collect his finds in. Additionally, you could consider buying him a book about mushrooms or a subscription to a magazine about foraging. Another option is to plan a mushroom hunting trip for the two of you, which could include a special lunch break where you prepare and enjoy the mushrooms you find together.
Or you can get him a star map with the date when he was born.
