Abstract:
The family Peyssonneliaceae comprises a worldwide group of non-calcified to calcified,
crust-forming red algae of great ecological significance. Of the genera currently recognized
in the family, Peyssonnelia has been widely considered to contain the largest number of
species, with five members reported for the Azores. Using rbcL as a molecular marker, we
here report on the taxonomic identity of recent collections of Peyssonneliaceae from the
Azorean islands of São Miguel, Graciosa and Pico, and compare those specimens in a
worldwide context. Only a single Peyssonnelia species, P. squamaria, is confirmed for the
Azorean archipelago, with three different haplotypes. Although the populations in the
Azores are genetically different from those occurring in the Mediterranean, this separation
appears to be relatively recent.
