Compact Plant Fiber Masses.

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.
