Moonmilk
Moonmilk is a very common cave deposit that probably precipitates from dripwater entering the cave, but forming very fine crystals rather than the larger ones typical of calcite deposits like flowstone. Moonmilk may take on shapes somewhat like those of flowstone. Micro-organisms such as bacteria, algae, and fungus have been found in moonmilk and may play a role in its formation, though not all moonmilk deposits contain such organisms
