Dimensions. Diameter of corallites (monocentric): 2–3 mm, in areas of intense budding around 1.5 mm; distance of corallite centers: 2–4 mm; septa/corallite: 18–24 + s, in corallites in areas of intense budding around 12; septa/mm: 5–8/2.

Description. Tamnasterioid-submeandroid colony; corallites irregularly disposed or arranged in short-meandroid series; septa subequal in thickness; up to 6 septa reach corallite center; columella made of a small number of papillae or twisted segments.

Type locality of species. Lower Hauterivian of France (Yonne) .

Distribution. Lower Valanginian of northeastern Switzerland (Vitznau Marl, Wart; this paper), lower Hauterivian of France (Yonne).

Material. NMSG Coll. PK–02.10.16b; –02.10.28h.

Remarks. In having larger dimensions of skeletal elements (corallite diameter: 2.5– 4 mm; septa/corallite: 25–30; septa/mm: 8/2), the material from the lower Cenomanian of Germany provisionally assigned to lamellosa in Löser (1998) differs from de Fromentel’s species. In forming a dimorphastreid corallum and having smaller dimensions of skeletal elements (septa/ corallite: 16–20 (24); septa/mm: 5–6/2), the material from the lower Hauterivian of France provisionally assigned to the species lamellosa in Löser (2001) differs from de Fromentel’s species. Te Swiss material corresponds well to the syntype of the species F. lamellosa (MNHN.F.M03558).
