英文摘要

An experiment on the culture of Physamm cinereum from spore to spore on sterilized bark and leaves in a moist chamber has been completed. The swarm cells escape through a deep wedge-shaped rupture in the spore walls. The posterior end of the swarm cell has a contractile vacuole and also sends out pseudopodia. They may be fused at their posterior ends. The swarm cell has flagella of equal length. One of the flagella is usually directed more or less straight forward, while the other is directed posteriorly at an angle greater than SO0 from the first. The plasmodium belongs to the type of phaneroplasmodium, which is almost colorless or watery-white. By using single spore cultures it has been proved that a single myxamoeba is capable of producing a plasmodium, which indicates that this organism is homothallic. Ultra-thin sections of the spore have been made, and the structures have been photographed under the electron microscope.
