BCs consist of an elliptical, narrow rim that is tightly connected to a vaulted central structure, made delicately of less regular crystallites. Several struts of one or two crystals width connect the dome-like distal cover with the rim, leaving pores in the perforate cycle, consistently present. No apical boss can be observed on top of the BCs’ central distal cover. CFCs possess a broad but low (height similar to width) leaf-like process, with a large arched opening.</p><p>Remarks: BCs are similar to those of <i>S. molischii</i> var. <i>molischii</i> HOL, but smaller and with noticeably less regular crystallites. The CFCs are distinctively different, having a well-formed arch and lacking the large leaf-like extension.</p><p>Dimensions: Coccosphere diameter c. 4–5 μm. BCs c. 0.8 μm long x 0.6 μm wide.
