A great wedding gift for your friend who loves mushroom hunting could be a custom made mushroom hunting knife or an outdoor mushroom hunting kit. You can also consider gifting them with a book on different varieties of mushrooms or a book on mushroom identification. If they love to cook with mushrooms, you could also consider giving them a recipe book on cooking with wild mushrooms along with some gourmet mushroom seasonings or truffle oil.
Or you can get her/him a star map with the date of the wedding.
