Description Test tubular, undivided, plane or plano-convex. Wall dark microgranular and hyaline, similar to the wall of the Howchiniidae Martini & Zaninetti, 1988 (i.e., the hyaline layer is eventually lacking). The hyaline layer is structurelesss or can display individualized pseudopillars. Aperture terminal simple, frequently, with additional sutural apertures which can be simple or protected by various appendices especially in the Permian genera.
Latest Viséan (Hemidiscopsis) (Cózar et al., 2015; Vachard et al., 2016b), Serpukhovian–Late Permian of Paleotethys; in North-America, the so-called lasiodiscids are generally cornuspirids (see in particular Groves, 1983; Krainer et al., 2015; Lucas et al., 2016a, b; Vachard, 2016b), nevertheless, some true lasiodiscoids are present in New Mexico (Groves, 1992; Lucas et al., 2016b; Vachard, 2016b).

Diagnosis Test discoidal to conical, proloculus followed by undivided enrolled tubular chamber; wall with finely granular dark inner layer and a clear vitreous and radially fibrous outer layer that is particularly concentrated in the umbilical region where it may form tubercles or pillars and may be perforated by canal-like fissures; aperture at end of the tubular chamber, and additional supplementary openings may occur along the spiral suture between successive whorls. L. Carboniferous (Visean) to Permian. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
