Scleroderma citrinum, known as the pigskin poison puffball, common earthball,or common earth ball, is the most common species of earthball in the UK and occurs widely in woods, heathland and in short grass from Autumn to Winter. Scleroderma citrinum has two synonyms, Scleroderma aurantium (Vaill.) and Scleroderma vulgare Horn. Earthballs are superficially similar to, and considered look-alikes of the edible puffball, but whereas the Puff Ball has a single opening on top through which the spores are dispersed, the earthball just breaks up to release the spores. Moreover, Scleroderma citrinum has much firmer flesh and a dark gleba (interior) much earlier in development than puffballs. Scleroderma citrinum has no stem but is attached to the soil by mycelial cords. The peridium, or outer wall, is thick and firm, usually ochre yellow externally with irregular warts.
