NOTES

This was morphologically characterized by Schneider (2004: figs 5-7) based on material from Bermuda, showing the nodal development and the presence of pseudoperiaxial cells. We chose a sequence (GenBank[AF259491]) from Yucatan, Mexico, to represent this species as it was obtained from close to the type locality, Honduras, and showed 3-4% genetic divergence (rbc L) from Pseudoceramium brevizonatum (H.E.Petersen) Barros-Barreto & Maggs , comb. nov. and P. oliveirarum Barros-Barreto, Maggs & M.A.Jaramillo , gen. nov., sp. nov.
