Boletus Calopus aka Bitter Beech Bolete?

Calvatia / Langermannia gigantea, Giant Puffball

Thanks to Peter the farmer for pointing me in the direction of this one and permission to walk across his land, a friendly chat while out Blackberry picking got around to the topic of mushrooms,he did forewarn me that this one would be past it's best.However it was worth the look as I haven't seen one in this last couple of years and what ever stage they are at they are a thing to marvel.
When they are young and fresh (firm with the flesh white throughout) they are simple to cook, peel and slice 2cm thick, season with salt and white pepper, panfry with butter until golden brown both sides.They go well with the usual things, eggs and bacon being good.
