) show that the test surface was originally covered with a veneer of fine-grained material. In some patches this appeared to be absent, exposing the tightly packed strands of the stercomare system. Under low-angled lighting, the strands created a hair-like surface pattern, even where the fine-grained veneer was present. The margin of the structure was often fairly even, but in places, possibly where damage has occurred, it has a frayed appearance with a fringe of exposed stercomare branches.

). Here, they are 75 to 150 µm, typically 90–120 µm, wide and branch but rarely anastomose.At least some of these sections probably represent the original margin of the test, although others appear damaged. Away from the edge, the strands lose their identity to varying extents. In places, they are still quite distinct. Elsewhere they become more tightly meshed and reticulated, with only chinks of space between them, and up to 200 µm wide. Sometimes they merge to form a more continuous sheet perforated by small open spaces.

The strands are of irregular width, generally between ~100 and 200 µm but occasionally somewhat wider. Some peripheral strands have slightly expanded ends. Away from the margin, the reddish strands can sometimes be glimpsed in gaps within the grey stercomare system.
