SEM-revealed cell wall sculpturing in Staurodesmus. SEM pictures of triradiate Staurodesmus species such as Staurodesmus cuspidatus and Staurodesmus dejectus usually show very regular, concentric series of fine cell wall striae. As those striae are seen in cells originating from quite different geographical regions it is supposed to be a species-specific characteristic. Yet, occasionially in seemingly similar species alveolate cell wall types are encountered raising a question after their taxonomic identity.
