Description:
Guinardia delicatula is a centric diatom that forms closely spaced chains without visible openings between neighboring cells. The cells themselves have a cylindrical shape and display girdle bands that are not prominently defined. A noticeable spine, visible in water mounts, protrudes from the valve’s edge. The valve surfaces are flat but rounded at the edges, especially where the spines emerge. The spine is oriented diagonally to the pervalvar axis and fits into a recess on the adjacent valve. Each cell contains 2 to 8 large chloroplasts, featuring prominent pyrenoids that may be less distinct in samples fixed with Lugol’s solution. There are no known resting stages for this species. The valves are flat, possess thin processes, and the cells contain 2-8 large chloroplasts, each of which has a sizable pyrenoid.
