Scleroderma citrinum is the most common species of Earth Ball in the UK and occurs widely in woods, heathland and in short grass from Autumn to Winter. Scleroderma citrinum may be referred to as Scleroderma aurantium in older texts.
Earth Balls are superficially similar to, and considered look-alikes of the edible Puff Balls, but whereas the Puff Ball has a single opening on top through which the spores are dispersed, the Earth Ball 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. An agaricoid puffball, Podaxis pistillaris, the False Shaggy Mane Lycoperdon perlatum Puffballs are fungi, they consist of a polyphyletic assemblage of Basidiomycota with gasterothecia (gasteroid basidiocarps) in which the spores are produced internally; that is, the basidiocarp remains closed, or opens only after the spores have been released from the... The term spore has several different meanings in biology. ... Mycelium is the vegetative part of a fungus consisting of a mass of branching threadlike hyphae that exists below the ground or within another substrate. ...

Tough puffballs with flish interiors, species of Scleroderma are sometimes called "earthballs" by field guide authors attempting to separate them from softer, fleshier puffballs.
The easily recognized Sclerodermacitrinum is well known and common, and famous for hosting the curious bolete Boletus parasiticus.
But the reader should be cautioned that Scleroderma species are defined on the basis of their spores by mycologists, and most identifications should be seen as tentative unless confirmed with spore analysis.
