Uniformly oval. Regularly spaced spikes. There is also a smaller spike-covered object (rod shaped?), just behind or in front of the large oval. (I can't tell where the focal plane is sitting.) The smaller object is visible in the lower panels of the photo composite, image 2. If the primary object is an egg case, what is the smaller spiky object? Perhaps the smaller object is a peal projecting from the large oval...like projecting panel from an opening chestnut. Interesting!

By far (>95%), this was the predominant specie netted during this collection... a bloom of C. longispina. Each cell has several, long siliceous spines and 2 flagella (one short, one long) http://www.diatom.org/lakes/taxa/chryso/Chrysosphaerella/TB-Chrysosphaerella_longispina.htm. Image 3 is a gif; careful inspection will show flagellar movement. -- The slide was allowed to dry and then reexamined after several days, see image 5. The drying process appears to have released some of the spines from the cells. Their double-headed nail-like structure is apparent in image 6 (also see http://cfb.unh.edu/phycokey/Choices/Synurophyceae/CHRYSOSPHAERELLA/Chrysosphaerella_Image_page.html)

16-cell colony. Each cell is tethered to a single stalk that converges, by tetrachotomous branching, in the center of the colony; there are 4 cells at the end of each major branchlet. The bottom frame in the composite photo (last photo) best shows the branching system. Compare to images here https://www.algaebase.org/search/species/detail/?species_id=176802&sk=0&from=results.
