A dried puffball (Calvatia gigantea) that has split open exposing a mass of
brown spores. The powdery spore mass has an unpleasant odor similar to old
urine. This puffball contains about 1.5 cups (375 ml) of spores. If the
volume of one spore is 0.000000062 ml, then the number of spores in this
puffball exceeds 6 billion. One puffball releases literally billions of
spores into the air in a cloud of brown dust. |
