Spore Print

Yellow/brown. Spherical with fine warts.

Taste / Smell

Excellent. Can be sliced and fried like a steak or breaded and fried for a better texture.


Grasslands, pasture, lawns, commons and roadsides. Found in rings, troops or individually. You will also find these in and around open woodland. They like to hide in amongst nettles and scrub. We have found them on steep sided woodland banks too.


Fairly common.

Possible Confusion

The only thing a Giant Puffball can be confused with is a football from a distance.

Breathing in the spores of this fungi can cause Lycoperdonosis a nasty lung disease so care should be taken when handling mature specimens.
