Descrição:

Hedriocystis undergoing division within faceted stalked capsule. Axopodia protrude from pores in capsule. Daughter cells become flagellated, escape the lorica then secrete their own stalk and lorica. Two of the five species in the genus have a spherical non-faceted lorica. Recently, a new genus, Penardiophrys has been erected for the faceted desmothoracid species such as this one. From freshwater pond near Boise, Idaho. Phase contrast. See Mikrjukov,K. Taxonomy and Phylogeny of Heliozoa I. Acta Protozool 39:81-97, 2000.
