Slime mold uses an externalized spatial “memory” to navigate in complex environments. These include periodic events of the mitotic cycle in Physarum polycephalum. The opening part covers two chapters on morphology, taxonomy, phylogeny, biosystematics, and evolutionary implications of Physarum and Didymium species. Physarales is of particular interest since the two best-studied myxomycete species, Physarum polycephalum and Didymium iridis, belong to this order and are currently subjected to whole genome and transcriptome analyses. 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. Find more information about this organism at . Class. Subclass: Endosporeae In Physarum Physarum polycephalum, a fast-growing species, is the most notable; it has been used widely in physiological experiments in protoplasmic streaming and nuclear behaviour.  Dussutour A, Latty T, Beekman M, Simpson J. S. 2010. The spores that are released are flagellated or amoeboid swarm cells in a motile stage and can remain dormant for many years. Physarum polycephalum.

When exploring a petri dish, it would not double back to where it has already been before. As the mold grows and pulsates throughout its environment, it leaves behind a trail of slime marking where it has been (hence the name). Live Physarum polycephalum Culture. Through experimentation, it has been found that slime mold can solve mazes and u-shaped traps (see below) to successfully locate a food source. Amoeboid organism solves complex nutritional challenges. 470176-642 470176-644. Amoebae can mate and fuse with others that have complementary mating alleles, thus making a new diploid plasmodia. Streaming of protoplasm is easily seen within the veins.
