Summary Calcofluor White inhibits the division of the marine nanoflagellateCryothecomonas longipes and causes the development of monstrously lobed cells. It disturbs the assembly of a putative noncellulosic fibrillar polysaccharide in the theca. The compact layer of the theca becomes thicker and wider, less densely packed and less rigid. The deposition of thecal components becomes uncoordinated. In consequence the initially unaffected coat of the theca and loose portions of the compact layer protrude from the cell surface. These are then convoluted, with the coat on their convex faces. The spacing of the coat ridges is increased here. The tension between the different layers obviously stabilizes the theca and contributes to its rigidity and elasticity.
