Enteridium lycoperdonis a cosmopolitan slime mould whose habitat is decaying wood. It can be quite variable in size and colour. Usually, it has a cap diameter of 5-80mm. It appears frequently throughout the year but is more prevalent during Spring. The plasmodium stage is white and is more or less rounded. A mature fruiting body takes on a silvery white colour from spore deposits. The dry, spongy interior produces copious amounts of red-brown spores in the manner of a puffball which it is not.
