										| Colacium vesiculosum, during the mobile phase the cells have a flagellum which is reduced when the transition to the sessile form happens. The sessile forms of C. vesiculosum have a stalk of gelatinous consistency. This specimen had stll a flagellum which could be recognized by the movement ( yellow arrowheads) |
