Original description: Morgenroth 1966, p. 20: Cannosphaeropsis ursulae Diagnosis: A species in the genus Cannosphaeropsis. Thin-walled central body.
16-18 relatively long, solid processes normaly support an envelope consisting of a fine meshwork.
Description: The thin-walled, spherical central body possess a smooth or at least a weakly reticulate surface. On the surface 16-18 evenly distributed, slender, solid processes are present. These support the concentric envelope, which consist in most of the specimens of a extremely delicate, differentiated meshwork (see text fig.12). The processes split up distally forming a fibrous meshwork, which is indistinct on some specimens. A thickening of the meshwork often results in an almost smooth, closed enveloppe. In almost all specimens an irregular shaped pylome, with a denticulate margin, is present. Splitting results in the development of a cap with 3-4 processes, on which the remains of the torn-off outer network are present.
Dimensions: central body diameter: 45-53 Ám; whole cyst diameter: 92-114 Ám; length processes: 6-25 Ám (measured: 100 specimens).
