Spores open in ideal environments and release a haploid amoeba. NatL Acad. Physarum cinereum. Kingdom: Fungi In moving, the plasmodium may move along many fronts that are connected by veins. So this slime molds name really means "many headed slime." The plasmodium is the active feeding stage of the organism and consists of a mass of multinucleate protoplasm. This stage of the life cycle, along with its preference for damp shady habitats, likely contributed to the original mischaracterization of the organism as a fungus. It ingests solid food particles in the same manner as an amoeba and can also absorb dissolved nutrients. Note: Some scientists are now classifying this organism in the kingdom Protista because of the way it moves around and feeds.
