Also placed under genus Teichaxinella. Orange, erect, cylindrical branches, single or divided, with the surface composed of thin, semihorizontal lamellae. Can be confused with Ptilocaulis walpersi, wich is usually more scarlet, and has the surface projections more spinous, round and blunt. They can be distinguished by the spicules (styles in P. walpersi, oxea in P. marquezi). P. marquezi is always much more uncommon than P. walpersi. Can also be confused in the field with Higginsia coralloides Higgin, 1877, which has oxea and acanthomicroxea spicules. |

Scarlet red to orange cylindrical branches, single or divided; sometimes laterally fused conforming a fan. Surface with spiny, round and blunt processes. Can be confused with P. marquezi (Duchassaing & Michelotti, 1864), which is usually more orange and has flattened lamellae in the surface. They are also distinguished by spicules (oxea in P. marquezi, styles in P. walpersi). P. walpersi is much more common (P. marquezi is rare). Can also be confused in the field with Higginsia coralloides Higgin, 1877, which has oxea and acanthomicroxea spicules. |
