Abstract

The stalk of Colacium mucronatum Bourr. & Chad. is composed primarily of a cylindrical shaft with a lightly staining inner core and diffuse peripheral cortex. The shaft and cortex arise from a ring‐shaped region around the canal opening whereas the core appears continuous with the canal which may be associated with initial cell attachment. All parts of the stalk, as well as the lining and contents of the reservoir, canal and flagellum exhibit stain reactions associated with neutral or mildly acidic carbohydrate with widely spaced anionic groups in low concentration.
