Giant puffball

Calvatia gigantea

This one has a dangerous look-alike

A button-stage Amanita — including the destroying angel — looks like a small white ball until you slice it and see the outline of a young mushroom. Always slice.

When
Typically August – OctoberAugust, September, October. Earlier in the south, later in the north.
Where it grows
Pastures, lawns, hedgerows and open woods — often a white ball visible from the road.
How to know it
Smooth white ball, football-sized or larger. Slice it top to bottom: it must be pure white and uniform like a marshmallow, with no gills, no outline of a mushroom, no yellowing.
Harvest and use
Slice thick and fry like a cutlet. Only while pure white inside.
Caution
Any yellow or olive inside means it is past it: discard.
