Please note that each and every mushroom you come across may vary in appearance to these photos.

Fruiting Body

White to off-white with a fine velvet like surface when young becoming smooth and papery. The inside of the fruiting body will turn to brown mature spores and these will be released when the mushroom ages, is damaged or even blown across a field like tumbleweed.


No stem although sometimes they can still be connected to the ground with a fine root like filament..


White becoming yellow then brown as it turns into spores.


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.

Possible Confusion

The only thing a Giant Puffball can be confused with is a football from a distance or possibly a Mosaic Puffball, pictured although the Mosaic Puffball has warts on the skin, the Giant Puffballs surface is smooth or maybe slightly velvety.

Spore Print

Yellow/brown. Spherical with fine warts. The spores come from the inside of the fruiting body and are brown. The ‘skin’ has come away in the image revealing the large mass of spores.

Taste / Smell

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


Fairly common.

Other Facts

This fungi has the most progeny of any living thing producing up to seven trillion spores on average. It has been estimated that if all the spores from two generations grew into mushrooms, they would produce something 800 times the volume of the Earth.
The spores used to be used by blacksmiths for burns and as a coagulant for staunching wounds.
Breathing in the spores of this fungi can cause Lycoperdonosis a nasty lung disease so care should be taken when handling mature specimens.

    The best ‘fact’ provided on the whole of the website is on this page. Can be confused as a football from a distance! Brilliant.

    I found something like this in my garden in a heap of dried leaves but it kinda small like an egg of a bird. But the characteristics are the same it’s color yellow inside and very soft. It’s white and firm in outside appearance.

    Found some of these on a field near us.
    So a younger specimen was selected and later divided into 1 1/2 cms thick slices/fingers
    Dipped in seasoned egg mixture then into Panko breadcrumbs.
    Fried, then enjoyed with some dipping sauce.
    Very like a more textured Tofu.

    Found a whopper this morning and plan to have a slice for lunch with bacon. It weighs 4lbs 11oz – is this a winner?!

      Hi Jenny, the record winner in the UK was 66.5 inches across found by a schoolboy in Yorkshire. It doesn’t mention any weight in the article.
