Morphology
Motility
Specialized structures	Trichomes are untapered with a single terminal heterocyst . However, when trichome length increases beyond a certain point, a heterocyst will form at the other end, followed eventually by midtrichome breakage. A single akinete or series of akinetes form adjacent to the heterocyst (Hirosawa and Wolk, 1979a,b). Cylindrospermum is slowly motile and does not produce specialized hormogonia. Individual sheaths are not produced, but a confluent mucilage holding many trichomes together is common.
