TheAllogromiida is an order of single-chambered, mostly organic-walledforaminiferans, including some that produce agglutinated tests (Lagynacea). Genetic studies indicate that some foraminiferans with agglutinated tests, previously included in theTextulariida or as their own order Astrorhizida, may also belong here. Allogromiids produce relatively simple tests, usually with a single chamber, similar to those of other protists such asGromia. They are found as both marine and freshwater forms, and are the oldest forms known from the fossil record.
