Based on the Lipman’s hagiastrid collection and original material, Late Cretaceous holotypes of the genera Histiastrum Ehrenberg, Hagiastrum Haeckel, and Tesserastrum Haeckel are revised. Histiastrum aster Lipman, H. cruciferum Lipman, H. membraniferum Lipman, H. latum Lipman, H. tetracanthum Lipman, H. tumeniense Lipman, Hagiastrum crux Lipman, and Tesserastrum quadratum Lipman are transferred to the genus Crucella Pessagno. A new species, Rhombastrum lipmanae sp. nov., is described. It is shown that Crucella lata (Lipman) and C. crux (Lipman) are Santonian–Campanian index species and C. crucifera (Lipman), C. tetracantha (Lipman), C. tumeniensis (Lipman), and Rhombastrum lipmanae sp. nov. are markers of the Campanian Boreal Realm.
