Hmmm, I'm not sure if there's a universal guide to this or anything - but my son loves mushrooms! He takes enoki mushrooms, button mushrooms (the brown canned ones), white button mushrooms (fresh ones for pasta) and shiitake mushrooms (usually in food/stir fried veg) too!
i feed them white button mushrooms, shiitake mushrooms and button mushrooms before!
