Common Earthball, Scleroderma citrinum, has ‘a characteristic smell of old rubber’ according to Wildlife of Britain, the Definitive Visual Guide or strong odour ‘of gas or acetylene’ (Encyclopedia of Fungi, Michael Jordan). As I’ve mentioned before, this didn’t stop me from slicing the young ones, with firm white flesh, and frying them in a bit of butter when I was trying to survive on a very slender travelling scholarship on a student field trip to Iceland. To me, they tasted of mushroom, but I don’t recommend that you try them, as they’re variously described as inedible or even poisonous.
These were growing by the path in deciduous woodland at the top end of the Pleasure Grounds at Nostell Priory Park.
