Description:

Lithocolla globosa a filose amoeba of uncertain affinity. Stiff filopods radiate uniformly from the spherical cell, which is covered with exogenous siliceous particles. The filopods lack axonemes and extrusomes unlike heliozoa with which Lithocolla may be confused. The cytoplasm of all individuals from this sample contains numerous dark red droplets or granules, possibly lipid (better seen in this image). Movement is accomplished by extension and withdrawal of the filopods. From temporary rainwater pool near Boise, Idaho. Oblique illumination
