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. Movement is accomplished by extension and withdrawal of the filopods. The genus is monospecific. From temporary rainwater pool near Boise, Idaho. Phase contrast..
