Inthis state the spores ripen ; but for the purpose of their dissemination a great elon-gation of the stem {st^ takes place ; the peridium is ruptured at the apex, the glebabecomes detached from the inner peridium, this latter splitting at ^, and the mem-brane t becoming detached below. The gleba is by this means raised up high above theperidium on the apex of the stem, while the stem attains the height of from 6 to 12inches. This elongation is brought about by the widening of its chambers, whichgive the mature stem the appearance of a coarsely porous sponge; it increases in
