Pleionastraea gen. nov. of the family Lithostrotionidae is described from the Lower Carboniferous Brigantian Stage of northern England. Two species, P. magnaP. matura, are referred to it. This astraeoid/thamnasterioid genus is distinguished from Orionastraea by its larger dimensions, but is considered to have followed the same evolutionary trend of a gradual breakdown of the corallite wall.
