Each spore of the slime mold, typically, gives rise to four naked cells, capable of active amoeboid movement and often pos- sessing one or more flagella. Each of these swarm cells, which are called myxamoebae, usually divides a number of times, producing more myxamoebae. Eventually, however, the cells fuse in pairs, each pair forming one zygote. Then the zygote gives rise to the Plasmodium of the next generation. Some myxomycophytes are parasitic and a few are important in relation to plant dis- eases. For example, the club-root disease of cabbages and the powdery-scab disease of.
