Cosmarium sp. (14) 

This is currently unknown and nothing found yet to compare it with. Appearing on the periphery there are single, relatively large granules combined with a series of vertical ridges in the semicell’s centre. In comparable forms with such central ornamentation, the granules along the margin are mostly smaller and generally doubled so that the outline is crenate. (Comments largely based on Frans Kouwets assessment.) Only a single cell has been found so far.
