An evidence describes the source of an annotation, e.g. Mycologia 75(1): 14-21. With no real brain or any way to internalize information, this organism essentially remembers or is reminded of where it has already been when it encounters its own slime again. The spores that are released are flagellated or amoeboid swarm cells in a motile stage and can remain dormant for many years. Example for "Physarum polycephalum": Taxonomy. Amoebae can mate and fuse with others that have complementary mating alleles, thus making a new diploid plasmodia. Amoebae:  Proc. Like slime molds in general, it is sensitive to light; in particular, light can repel the slime mold and be a factor in triggering spore growth. 5. Sporulation ends with rupture and release of spores. It takes on many shapes and sizes throughout its life, morphing from microscopic amoeba to a multinucleate syncytium which can be as large as several feet across, and then forming millimeter-scale delicate, mushroom-like fruiting bodies. Small plasmodia can be fragmented into microplasmodia. The opening part covers two chapters on morphology, taxonomy, phylogeny, biosystematics, and evolutionary implications of Physarum and Didymium species.

So this slime molds name really means "many headed slime." 1976 April 1; 69(1): 223–226. Acellular slime molds ( Myxomycetes ) are distinguished from cellular slime molds ( Acrasiales ) because the plasmodium (which is diploid) is a syncytium produced by multiple nuclear divisions (karyokinesis) without cytokinesis. polyphyletic origin of the genus Physarum and calls for a reevaluation of current taxonomy. Directions are given for: acquiring the organism; activating it; observing its life cycle; and viewing protoplasmic streaming. Vol. 8. Physarum cinereum. Note: Some scientists are now classifying this organism in the kingdom Protista because of the way it moves around and feeds. These swarm cells then come together and fuse, thus creating new diploid plasmodia. It crawls towards its food, surrounds it, and secretes enzymes Subclass: Endosporeae When exploring a petri dish, it would not double back to where it has already been before. It can stay this way for very long periods of time until the environmental conditions are right for it to become vegetative again. Hosoda,E. Physarum polycephalum (PSRMPO) ... Propose photo. The diploid cells are uninuculeate, but will become multinucleate if cultured. NatL Acad. Through experimentation, it has been found that slime mold can solve mazes and u-shaped traps (see below) to successfully locate a food source. P. polycephalum is considered to be a large single celled organism with multiple diploid nuclei, meaning there are no cell walls to distinguish each nuclei. Mycetozoa. Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. As the mold grows and pulsates throughout its environment, it leaves behind a trail of slime marking where it has been (hence the name). The species page of 'Physarum polycephalum'.

The slime mold Physarum polycephalum provides an easily maintained classroom plant which can act like an animal. Like slime molds in general, it is sensitive to light; in particular, light can repel the slime mold and be a factor in triggering spore growth. Olive defines the Mycetozoa as consisting of three distinct groups ().The true or plasmodial slime molds (Myxogastria—e.g., Physarum polycephalum) are amoeboflagellates, most of which develop into large, reticulate plasmodia with >10 4 synchronously dividing nuclei. Physarum is a genus of plasmodial slime molds grouped within phylum Amoebozoa. 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. With a tendency to be very easy to cultivate in the lab, it is used to study mitosis, streaming/cell motility (the movement), and basal forms of intelligence.
