Strobilidium sphaericum Lynn et Montagnes 1988

A = Cell in Lugol; B = Arrowheads=somatic cilia (DIC)


Life-form: Solitary

Size: Cell length 40-70 µm, width 40-60 µm

Resting spore:

Note: It is better to study it with the help of the protargol method (Montagne & Lynn 1987). This species was referred to the genus Rimostrombidium by Petz & Foissner (1992)

Distinctive features: External polykinetid zone composed of 24-30 polykinetids, 9-11 ciliated somatic kineties, C-shaped macronucleus (Lynn & Montagnes 1988b)
