For instance, D. gloeosporum, which owes its name to its extremely sticky spore matrix, (57) is the single dictyostelid member of the clade of white polysphondylids (Fig. 3) . The branched whorls of the polysphondylids are formed when a group of cells detaches from the rear of a rising cell mass and then forms new tips (Fig. 4) . D. gloeosporum may owe its consolidated single spore head to the fact that, due to the highly adhesive matrix, detachment of cell masses does not occur. Similarly, other fruiting body architectures are likely to result from interaction of the cAMP signaling network with different biophysical environments, rather than being controlled by architecture-specific genes.
