Parasols are very tasty! I've hear someone says it can be cooked so that the dish will remind 4 different kinds of meat. Sounds amazing.
Puffballs are edible too but it is specific fungus due to its texture. Dont pick them after rain - thus they will soak water alot and turn into jelly. A good way is to dry them, grind and use the powder for adding into soups and dishes later, to give them extra smell and mushroom taste.
