E. Landing 1995 | Species of Strictocorniculum with straight, very elongate elements with circular or weakly laterally compressed cross sections.
Elements do not seem to show anteroposterior, lateral, or helical curvature; longitudinal sculpture (i.e., costae or sulcae) absent; elements have a circular or slightly laterally compressed cross section; surface microsculpture consists ofapically inclined, low, blunt nodes arranged in rhomboid pattern with fine ridges connecting adjacent nodes; elements slender, with low apical angle (ca. 3?); internal cavity large and element wall relatively thin; large fragmentary specimens suggest elements reach 8.0 mm length. | |
