FIGS. 11 and 12. FIG. 11. Clouds of D. mucoroides strain S2 in various stages of development. Note the definite centre
within the top one, local concentrations of clumps within the top two, virtual absence of clumping in the next one down
on the left, and sub-clouds within the bottom system on the right. FIG. 12. 1^ hours later. Note the rapid completion of
aggregation once definite centres have become active, the expansion of the cloud on the left, and the relatively small
progress made by the others.
