Now Adnatosphaeridium?. Originally Cannosphaeropsis, subsequently Adnatosphaeridium, thirdly (and now) Adnatosphaeridium?.
Holotype: Cookson and Eisenack, 1962, pl.4, fig.8
Locus typicus: Carnarvon Basin, Australia

Original description: [Cookson and Eisenack, 1962, p. 493]:
Description:
Shell sphaerical to subsphaerical with numerous apparently solid appendages that widen abruptly at their ends into flat membranous funnels, the rims of which may be slightly recurved. Sometimes the appendages are so numerous that they overlap one another. The ends and stalks of adjacent appendages are more or less completely connected by delicate transparent membranes, which in some examples have been partially or almost completely destroyed. The appendages frequently show a fibrillar structure but may be even.
