Shells unilocular, sometimes pseudocolonial or pseudochambered, of subsphaerical, elongated, tubular, stellate, branching or other irregular form; wall monofontinal, sometimes the pseudopores are visible, tectinous in Lagynana and Ammoscalariana, agglutinated or microgranular in Astrorhizana, may be simple or partly subdivided by the partitions in the Lagynana and Astrorhizana, in the latter may be thickened from the inside (spongy, labyrinthic); aperture may be entirely absent, may be primarily multiple (openings often irregular in form and position or situated at the end of the tubes), or single in more advanced forms (usually of definite form and position, may be slightly elevated on the neck, may have a small lip); agamonts uninuclear, nuclear dualism unknown, gametes biflagellate or amoeboid (in some Lagynana); free-living or (very often) attached, [among Lagynana freshwater forms are also met, two genera (Rhynchosaccus and Thalamophaga) are parasitic]. Cm - Holocene. Subclasses Lagynana Mikhalevich, 1980, Ammoscalariana Mikhalevich, 1980 (insufficiently studied), Astrorhizana Saidova, 1981.
