Common earthball

The rounded fruitbody is stemless and attached to the ground by white mycelial threads, typically 4 to 10 cm across and 3 to 6 cm tall. The tough thick skin of the earthball is initially white, cream or yellow and may turn ochre-brown or green as it ages. It is covered by a network of coarse scales of irregular shapes and variable size. Inside the earthball the spore mass is almost white at first but soon turns brown with white marbling before becoming purple-brown throughout. At maturity the skin ruptures leaving a large, irregular opening via which the wind and rain disperse the spores. Empty earthball cases can persist for many months in sheltered woodland hollows.
