A, Chain in broad girdle view; B, Resting spores within the mother cells of a chain; C, Sibling intercalary valves showing overlapping silica ear-like structures (arrowhead); D, Released resting spore. E, Terminal valve with external process of rimoportula (arrowhead) and fringe (arrow); F, Parallel rows of poroids on the mantle; G, Central annulus (arrow) on terminal valve; H, Girdle bands; I and J, Seta structure. Scale bars, 20 μm (A, B), 6 μm (D), 4 μm (C), 2 μm (E, F, G, H, I, J).
