Dense aggregating fields of P. violaceum and P. pallidum exhibit propagated waves which may be analogous to those seen in Dictyostelium discoideum. As in D. discoideum the wave velocity is determined by an intracellular delay between stimulation and response, rather than by the diffusion coefficient of the acrasin. The frequency of the propagated wave overlaps that of aggregating D. discoideum, so that absence of coaggregation reported by Raper & Thom is unlikely to be based on specificity of the propagated wave parameters, but rather on a difference in the chemical acrasin itself, as argued on independent evidence by Bonner. Despite this difference in the chemical nature of the acrasin, the presence of propagated waves in Polysphondylium with frequencies similar to those in D. discoideum, taken together with evidence for a diffusible acrasin, suggests that the mechanism of aggregation is substantially the same in both genera.
紫盘菌和苍白盘菌的密集聚集区域呈现出传播波，这可能类似于在盘基网柄菌中观察到的波。与盘基网柄菌一样，波速由刺激和反应之间的细胞内延迟决定，而不是由聚集素的扩散系数决定。传播波的频率与聚集的盘基网柄菌的频率重叠，因此，雷珀和汤姆报告的不发生共聚集现象不太可能基于传播波参数的特异性，而更可能是基于聚集素本身的化学差异，正如邦纳基于独立证据所论证的那样。尽管聚集素的化学性质存在这种差异，但多盘菌中存在频率与盘基网柄菌相似的传播波，再加上存在可扩散聚集素的证据，表明这两个属的聚集机制基本相同。
