Met a lady in the dog run. Chatted. "Oooh, puffball mushrooms!" she said. Huge gigantic clump of puffball mushrooms at her feet. Apparently they're edible. Being doggy people, we both had spare poo bags with us; we split the hoard. Came home, checked online that they *are* the edible kind. Deciding now whether to make mushroom pasta or soup.
