Escharisphaeridia "nuda" Prauss, 1989, p.33, pl.10, figs.2-3; text-fig.10.
Holotype: Prauss, 1989, pl.10, fig.2; text-fig.10. Taxonomic senior synonym: Escharisphaeridia laevigata, according to Prauss in Lentin and Williams (1993, p.213). Taxonomic senior synonym: Escharisphaeridia psilata, according to Poulsen (1996, p.80) - however, Feist-Burkhardt and Monteil (1997, p.40) retained Escharisphaeridia nuda as a taxonomic junior synonym of Escharisphaeridia laevigata.
