The tasty vesse de loup géante or giant puffball (Calvatia gigantea) grows in meadows and woodlands from June to November, and is always spectacular when you find a big one. Slice it up and fry it in butter.
Also known as the tête de mort or lycoperdon géant.
Lycoperdon pyriforme or vesse de loup en poire is the common puffball that grows on decaying wood in late summer and autumn, and is edible, but not that tasty and not a fungus many people seek out.
