Hystrichosphaeridium floripes
Hystrichosphaeridium floripes Deflandre and Cookson, 1955
Now Homotryblium. Originally Hystrichosphaeridium, subsequently Cordosphaeridium, thirdly (and now) Homotryblium.
Taxonomic junior synonym: Homotryblium plectilum, according to Bujak in Bujak et al. (1980, p.64) — however, Lentin and Williams (1985, p.168) retained Homotryblium plectilum.
Holotype: Deflandre and Cookson, 1955, pl. 7, fig. 1
Locus typicus: near Denmark, W Australia
Stratum typicum: Early Tertiary
Original description: Deflandre and Cookson, 1955, p. 276
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.
