Peyssonneliales
Peyssonneliales is a monotypic order of red algae belonging to the class Florideophyceae and the subclass Rhodymeniophycidae. It contains only 1 known family, Peyssonneliaceae . The type species is ''Peyssonnelia'' History Genera ''Peyssonnelia'' and ''Sonderopelta'' were originally in order Gigartinales but comparative morphology and rbcL and nuclear LSU rRNA sequence data showed that they were separate and therefore order ''Peyssonneliales'' was established in 2009 to hold them both. ''Incendia'' was initially resolved as a monophyletic clade with full support for rbcL. Then using robust rbcL phylogeny, order Peyssonneliales was lso resolved as monophyletic with well-supported main lineages. Description Delineation of the various genera in the Peyssonneliaceae had mostly been based on vegetative characteristics. Peyssonneliales order algae are red, crustose, prostrate, and usually epilithic (growing on the surfaces of rocks). The crusts may be non-calcified throughout, Cal ...
