Archaeolithophyllum is a genus of conceptacle-bearing red alga that falls in the coralline stem group. It somewhat resembles Lithophyllum.^[1]^[2]

As of today, Archaeolithophyllum is the only Palaeozoic coralline to bear clear conceptacles,^[3] although the earlier Graticula does bear reproductive structures.^[4]

It mineralized using aragonite.^[3] Its conceptacles are cone-shaped protrusions that extend outwards from the thallus surface and have a single central opening.^[5] It probably encrusted muddy or sandy surfaces.^[5]
