Acrasiomycota is a phylum of slime molds which belongs to the protist group Discicristata. The name acrasio- comes from the Greek "Akrasia", meaning "acting against one's judgement." This group consists of cellular slime molds.

Some would also consider it as a kingdom unto itself, but the debate is as of yet unsettled.

Reproduction

When resources, such as water or food become limiting, the amoeba will release pheromones such as acrasin to aggregate amoebal cells in preparation for movement as a large (thousands of cells) grex or pseudopod. When in the grex, the amoeboids reproduce sexually, resulting in fruit-like structures called spores, which develop into unicellular molds of the same species.
