Durinskia (dew-rink-see-a) baltica (Levander 1894) Carty and Cox 1986. The images show cells in ventral view. The red stigma is visible in the sulcal area. The plastids are yellow-brown and multiple. The cingulum is in the middle of the cell.

Durinskia baltica cells are round from the ventral side, slightly dorso-ventrally flattened, 16 - 28 microns long, 15 - 27 microns wide, and approximately 19 microns broad. Thecal plates present: an apical pore, a canal plate, 4 apical plates, 2 anterior intercalary plates, 7 precinguluar plates, 5 cinguluar plates, 4 sulcal plates, 5 postcingular plates, 2 posterior plates. Second apical intercalary plate much larger than the first and extending across the dorsal side. Cingulum 2-3 microns wide, consists of 5 plates, including a transitional plate. The large anterior sulcal plate forming a list over the left sulcal plate. Thecal plates smooth, with scattered pores (about 0.2 microns). Pores form a row along the edge of the cingulum. Nucleus round, in the centre or in the left side of the cell, approximately 7 microns. Reddish stigma, approximately 4 microns long, present in the sulcus. Yellow- brown plastids, 2 - 3 microns diameter, scattered throughout the cell.

Peridinium quinqucorne cells are diamond shaped to ovoid, with a pointed apex, and a number of projections from the hypocone, 20 - 25 microns long, 15 - 18 microns wide. Thecal plates present: an apical pore, a canal plate, 3 apical plates, 1 anterior intercalary plate, 7 precingular plates, 5 cinguluar plates, sulcal plates not known, 5 postcingular plates, 2 posterior plates. Small apical pore present, in a short apical horn. Cingulum 4 - 5 microns wide, number of plates not recorded. The large anterior sulcal plate forming a list over the left sulcal plate. Four spines (4-5 microns long) project from the antapical plates. Thecal plates smooth, with scattered pores. Intercalary bands may be wide on some cells. Nucleus round, in the centre of the cell, approximately 7 microns diameter. Reddish stigma, present near the beginning of the sulcus. Yellow- brown plastids, 2 - 3 microns diameter, scattered throughout the cell.
