Clionolithes alcicornis (Vogel, Golubic et Brett, 1987)

Emended diagnosis. Branches diverge from the flat and elongated main trunk, spreading radially and in one plane, often in straight lines, ramifying in varying density at angles between 40° and 115° without forming anastomoses, tapering toward pointed tips. Often with a distinctive cuspate texture and fine filaments scattered over the entire surface, but most numerous on the edges and sides of the branches.
