New Species - Brown Puffball

Another fungi species for the site list - the Brown Puffball (Bovista nigrescens). I removed the slugs around it so rather than see it eaten I could watch it over the time it gradually matured, turning as it does so from white to dark brown. It will end up freeing itself from its tenuous connection into the earth and rolling away with the wind scattering spores as it goes. The photos show it on the day I found it and nine days later.
