Geastrum britannicum is a fungal species in the family Geastraceae. Its recommended English name is vaulted earthstar.[1] Like other earthstars, the basidiocarps (fruit bodies) are initially globose. Their thick outer skin splits open at maturity to expose the puffball-like spore sac surrounded by the split rays of the outer skin. In the vaulted earthstar, the rays split apart and form an arch, raising the spore sac upwards.
