Original Description

Test trochospiral, composed of two or more whorls of subglobular or reniform chambers, initially with about 5 chambers per whorl, final whorl of about 6 chambers; spiral side completely evolute, umbilical side almost completely involute, with a small, deep umbilicus; aperture a low interiomarginal arch, intraumbilical-extraumbilical in extent; wall microperforate, the surface covered by anastomosing ridges which enclose groups of microperforations in a favose reticulation.

In honour of Pietro Ascoli, who first recognised the stratigraphical significance of the type species

Extra details from original publication
Remarks. Ascoliella appears to evolve from Favusella in the Aptian by migration of the anterior end of the aperture beyond the umbilicus, and is therefore the only known example in the Favusellacea of a parallel to the evolution of Blefuscuiana from Gorbachikella in the Praehedbergellidae, Globigerinacea. Ascoliella persists to the Late Albian, because the species “Favusella” pessagnoi Michael (Fort Worth Formation), “F.” quadrata Michael (Duck Creek Formation) and “F.” nitida Michael (Duck Creek Formation) are all referable to it. Ascoliella appears to become extinct before the top of the Albian, whereas Favusella persists into the Early Cenomanian (Michael, 1973, p. 203).
