Notes: Brown, thin to thicker, smooth to undulate, erect branches with scattered oscules. Spicules are acanthostyles. May be confused with club-shaped individuals of Agelas dispar (Duchassaing & Michelotti, 1864), also pictured here, which are thicker. Also with flat-branched individuals of Agelas dilatata Duchassaing & Michelotti, 1864), pictured here, which usually are lighter in color (tan) and arise from a wider base (A. cervicornis usually arise from a narrow base).
