Description and Significance
This species was first described by Edgar W. Olive in 1901 as growing on the dung of a donkey, muskrat, and rabbit in Liberia.
Polysphondylium pallidum is a cellular slime mold of the phylum Mycetozoa. It begins its life as a single-celled amoeboid protist and lives in feces, soil, and other organic matter (1). Like other cellular slime molds, P. pallidum can reproduce both sexually and asexually depending on its environmental conditions (1) and has two distinct stages of its life cycle: a vegetative non-social stage and an aggregate phase which is cued by starvation (5).

Genome Structure
Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
