From Fensome et al., 2019:
(Brosius, 1963, p.40–41, pl.6, fig.1; text-fig.2, nos.11a–c) Sarjeant, 1981, p.120. Holotype: Brosius, 1963, pl.6, fig.1; Fensome et al., 1993a, fig.1 — p.1021. NOW Cordosphaeridium. Originally Hystrichosphaeridium, subsequently (and now) Cordosphaeridium, thirdly Tityrosphaeridium. NIA. Age: Late Oligocene.

Original description: Brosius 1963, p. 40-41: Hystrichosphaeridium cantharellum
Diagnosis: A species of the genus Hystrichosphaeridium with the following special characteristics: The spherical to ovoidal, smooth inner body bears about 15-20 hollow tree-like processes. These are mostly broad and cylindrical, narrow slightly in the middle and broaden weakly distally. They are composed of fibres, that are split distally and strongly combed backwards. Sometimes net-like openings occur. At the ends, the processes always seem felt-like, but upon high magnification their fibrous character is revealed. Within a single specimen narrow and wide processes occur. As a hatch, a calotte may be split off.
Dimensions: holotype: shell diameter 54 µm, process length 30 µm. Mean shell diameter 50-57 µm, process length 15-28 µm, process diameter 2-8 µm (10 specimens measured).

Tityrosphaeridium cantharellus (Brosius, 1963) Sarjeant, 1981. Brosius (1963, p.40-41) noted that the spherical to ovoidal central body bears 15-20 hollow, palmtree like processes. These are mostly broadly cylindrical and considerably broadened at their distal ends. Size: capsule diameter 50-57 µm, length of processes 15-30 µm, diameter of processes 2-8 µm.
