Hyperammina elongata, from here.

Belongs within: Foraminifera.

The Hyperamminidae were treated by Cushman (1940) as a family of Foraminifera with an elongate, undivided, agglutinate test. The Hippocrepininae (with test free) and Dendrophryinae (with test attached) were later placed by Loeblich & Tappan (1964) as independent subfamilies within the family Astrorhizidae; as the latter group is now known to be polyphyletic and the position of the taxa listed below is uncertain, Cushman's 'Hyperamminidae' is retained here for the sake of convenience.

Characters (from Cushman 1940): Test free or attached, consisting of globular proloculum and more or less elongate (but not close coiled), sometimes branching portion, not divided into chambers; wall of variously agglutinated materials with basal layer of chitin; aperture formed by open end of tubular portion.
