The puffballs are back. Calvatia gigantea. They always appear in the small field between the house and the front pond.
This one has got even bigger since I took this photo – and somewhat dirtier-looking; I suspect that it is no longer edible. Past its best at any rate.
Here is one from a couple of years ago. It’s at the edible stage – no hint of spore formation.
It tastes of mushroom, basically, and one slice is enough in my opinion. I don’t know how you’d eat a whole one.
