ABSTRACT: "Peyssonnelia Decaisne comprises a worldwide group of non-calcified or calcified, crust-forming red algae of great ecological significance, with some species involved in the establishment of rhodoliths. Of the eight genera currently recognized in the family, Peyssonnelia, is widely viewed to contain the largest number of species. The number of distinct species of Peyssonneliaceae present in the Gulf of Mexico has increased from 6 to 21. Comparative morphology, chloroplast-encoded rbcL and nuclear LSU rDNA sequence data suggest that species of Peyssonnelia do not occur in the Gulf of Mexico, and that previously reported Peyssonnelia species for the region actually belong to other genera of the Peyssonneliales."
