%X The life history of myxomycetes is of importance for studying diversity of nutritive modes and phylogenesis of these organisms. Until now the reports concerned were few. Oat-agar culture method, moist chamber culture method and scanning electron microscopy were used to study the process of the ontogeny of Physarum compressum. The life cycle of spore-to-spore were completed in agar culture in Petri dish. The result shows that the life cycle of Physarum compressum comprises a unicellular amoeboid or swarm cell stage, a multinucleate plasmodium stage and a sporulation stage. The spore is globose and the spore surface is minutely spiny. The spore germinates by means of a cracked open and releases a single myxamoeba. The plasmodial type is of phaneroplasmodium. The mature plasmodium is milk-white, which can form many sprangia. Spores developed on agar are fertile and resemble those on natural substrate.
