A taxonomic group or order within the classification of slime molds (Acrasida), tiny organisms that live in soil and can behave as individual cells or collective bodies.
From Acrasida (the group name) plus -eae, a Latin plural suffix used in biological taxonomy. The root Acrasi- may relate to the organism's seemingly chaotic movement patterns.
Slime molds in Acrasieae are unicellular but can form multicellular colonies that hunt, migrate, and solve mazes—in 2022, one species was described as solving problems without a brain, challenging how we define intelligence itself.
