Common Earthball
This very common mushroom appears to be responsible for the most mushroom poisonings each year in the UK. This is possibly due to confusion with Common Puffballs or even Truffles. There are three types of Earthball in the UK, Scleroderma citrinum (Common Earthball), Scleroderma areolatum (Leopard Earthball) and Scleroderma verrucosum (Scaly Earthball), all are similar but the Scaly Earthball is darker in colour.
Mushroom Type | |
Common Names | Poison Puffballs, Leopard Earthball, Scaly Earthball |
Scientific Name | Scleroderma citrinum, areolatum, verrucosum |
Season Start | Jul |
Season End | Nov |
Average Mushroom height (CM) | 8 |
Average Cap width (CM) | 12 |
Fruiting Body
Generally spherical, irregular or potato shaped. Ranging from white to tan to brown with a darker wart like covering and a thick leathery skin.
Flesh
Inside the mushroom has a purple/brown to black interior with small white ‘veins’ running through. When very young the interior of the mushroom can appear whitish or slightly pink/purple but is never pure white like a Puff Ball. When mature the interior becomes powdery and the outer skin will develop pores or splits through which the spores can be distributed when the mushroom is disturbed or rained on.
Spore Print
Brown. Globose with a net like covering.
Taste / Smell
A bit like rubber.

If I send a photo of a mushroom thing I found in the garden would you be able to identify it
Possibly, we would need clear photos of the caps, gills and stem to have a chance, send them to [email protected] and I’ll see what I can do.
Thankyou for your clear identification. I have lots of these growing on my veg patch. Will they do any harm? Should I get rid of them, if so, how?
They shouldn’t do any harm, they might even be doing good.
We have found a fungi in an elongated ball shape with a bright orange spongey interior at the end of our garden on the edge of a forest under an old oak tree, growing on woody matter, bark clippings etc I can’t identify it. Do you have any idea what it might be please?
If you can send in clear photos of the mushroom from above and below and the interior to [email protected], I’ll try to ID it for you.
What happeneds if you inhale the powder
As the mushroom is poisonous, it could cause serious illness. People who have consumed them thinking they were edible puffballs usually end up in hospital.
