| Description of Campanella umbellaria: Sessile, colonial peritrich ciliates, with bell-shaped bodies on moderately thick, non-contractile branching stalks. Pellicle finely annulated. Peristome widely spread. Horseshoe-shaped macronucleus. William Saville Kent records the size as 130-350 micrometres, a range which Alfred Kahl calls improbable. |
