Spotting

Very, very tasty and aromatic mushroom, eating at a young state when the meat is white.

Puffball I say. My grandparents used to eat them.

A cut-away would be useful, showing gills. My first impression was a Coprinus atramentarius or something like it, but with no stem or gills visible it's impossible to say. The way this group is, it almost looks like a weird puffball.
