Astrorhizana are a subclass of foraminifera characterized by simple tests composed of agglutinated material that can be irregular, spheroidal, or tubular and straight, branching or enrolled. Tests are non septate and consist of a single chamber following the proloculus. These are the Ammodiscacea of the Textulariina in the Treatise Part C, (Loeblich & Tappan 1964) that range from the Cambrian to Recent.
Four orders are included, the Astrorhizida, Dendrofryida, Hippocrepinida, and Saccamminida.
