PUFF-BALL

The puff-ball (Lycoperdon) is a genus of gasteromycetous fungi, several species of which are found in Britain. When they first appear they are masses of solid nearly homogenous, white flesh; but as they grow older the white colour gives way to brown and the solid mass is replaced by a dry and shrivelled rind or casing containing within the spores as a fine brown powder.
