Most of the non-biogenic grains are ~35 µm or less in size, although some are larger. At least one agglutinated foraminiferan test is incorporated into the wall. Where the edge of the test is intact, the wall continues around it with no obvious apertures. The overall colour is dark grey, influenced by the stercomare that largely fill the test and are dimly visible through the thin wall.

The cytoplasm is visible on broken edges as pale whitish strands enclosed within a delicate, transparent granellare tube, as well as larger, more irregular masses, notably in the stem.

wide. The test wall contains a high proportion of sponge spicules, and the interior is partitioned into compartments that are occupied by stercomare masses of irregular width (typically 200–300 µm) and granellare strands (65–80 µm wide). The main difference is that the test is curled around to form an almost tubular structure. Possibly, they are conspecific, but this cannot be confirmed in the absence of genetic data.
