Cordosphaeridium floripes
Cordosphaeridium floripes, (Deflandre and Cookson, 1955), Eisenack 1963
Now Homotryblium. Originally Hystrichosphaeridium, subsequently Cordosphaeridium, thirdly (and now) Homotryblium.
Tax. sr. synonym of Homotryblium plectilum Drugg and Loeblich Jr., 1967, according to Bujak in Bujak et al., 1980. Stover in Lentin and Williams, 1985, considered Homotryblium plectilum to be a separate species.
Holotype: Deflandre and Cookson, 1955, pl. 7, fig. 1
Locus typicus: near Denmark, Western Australia
Stratum typicum: Early Tertiary

Original description as Hystrichosphaeridium floripes: [Deflandre and Cookson, 1955, p. 276]:
Description:
Shell globular, with about 16-18 tubular processes not communicating with the interior. Processes generally consisting of from 2 to several tubes joined along the greater part of their length, the individual tubes widening and sometimes separating from one another distally. Proximally the peripheral tubes widen considerably as they fuse with the membrane of the shell, forming on its surface a clearly defined flower-like design. Sometimes the processes may consist of a single tube with a rounded base. Membrane of shell thin and finely reticulate.
