Life History:
In France, Myrionema plants with plurilocular organs released zooids which: 1) fused to either form a branched filamentous plant resembling the parent plant and bore both plurilocular and unilocular organs, or 2) formed a small disc which bore both plurilocular and unilocular organs. Zooids from the unilocular organs either fused and recycled the disc stage, or did not fuse formed a branched uniseriate plant which bore plurilocular organs. Isolates from Germany, started from plurilocular plants recycled directly via plurilocular organs.
