In vivo portrait of Nassula exigua (KAHL,1931). This small species has an aggregate of orange brown refractile droplets (possibly lipid) at the left anterior end toward the dorsum. Collected from an organically enriched alkaline ephemeral puddle with abundant filamentous cyanobateria near Boise, Idaho 43° 36' 49.63"N 116° 13' 23.31"W. August 2006. DIC.

Ventral infraciliature of Nassula exigua (KAHL,1931). There are only three small nassulid organelles extending to the left from beneath the cytostome (yellow arrowheads). The right paraoral membrane is composed of inclined dikinetids (red arrowhead).There is a single ventral contractile vacuole excretory pore (blue arrowhead). The cytopyge appears as a longitudinal linear structure just to the right of the first somatic kinety (green arrowhead). Collected from an organically enriched alkaline ephemeral puddle with abundant filamentous cyanobateria near Boise, Idaho 43° 36' 49.63"N 116° 13' 23.31"W. August 2006. Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991).Brightfield.

Macronucleus and micronuclei of Nassula exigua (KAHL,1931). The macronucleus and two micronuclei are visible here.Collected from an organically enriched alkaline ephemeral puddle with abundant filamentous cyanobateria near Boise, Idaho 43° 36' 49.63"N 116° 13' 23.31"W.
