When they have become full-grown they lose a good deal of their moisture, and the protoplasm then sepa- rates itself into a great number of minute rounded balls, each of which forms a cell-wall around itself. These little balls (spores) are thus nothing but bits of protoplasm secure- ly covered. They may now be blown, hither and thither without harm, and when at last they fall into a moist warm place they imbibe water, burst their coats, and are free.
