Material examined. BC040 RC1698 (morphology).
Description. The two illustrated fragments are around 7 and 19 mm in maximum dimension. The larger (Supplementary Fig. S2B View FIGURE 2 ) forms an irregular mass that is perforated by several open spaces, up to 2.20 mm across, so that parts of it appear broadly reticulated. The smaller (Supplementary Fig. S2A View FIGURE 2 ) has a single round open space, 1.24 mm in diameter, that is surrounded by broad bars, between 1.40 and 2.00 mm wide.
Both fragments are pale yellowish brown, with a smooth, generally finely agglutinated outer surface. However, the wall also incorporates relatively large, black grains, probably fragments of micronodules, that are concentrated in certain areas. This is most clear in the smaller fragment, where the dark grains occur mainly in bands across the bars, in one case being largely restricted to a distinct zone where the largest grain is 230 µm in size. The test wall is very delicate and no more than about 30-40 µm thick. There are no internal xenophyae and the test interior is filled with dark grey decayed stercomare.There is no sign of granellare.
Remarks. The thin, delicate wall composed of mineral grains and the absence of internal xenophyae suggest a placement for these distinctive fragments in Aschemonella .
