Typifications and nomenclatural issues in the Order Peyssonneliales (Rhodophyta) – problems and solutions.

Peyssonnelia squamaria is a red algae that was described by Gmelin in 1768, from a collection from the Mediterranean sea.  Precise location information for this sample was not indicated in the protolog.  Gmelin classified this algal as a fucoid algae, namely, Fucus squamarius, then in 1842, it was reclassified by Decaisne as a red algal genus new to science.  The new combination of the species became Peyssonnelia squamaria and is now the generitype of Peyssonnelia.  A type sample of the species was never selected, and the collection used by Gmelin at present is accepted by many as lost.  This represents a large problem in taxonomic research that has been conducted within Peyssonnelia and the Peyssonneliaceae within the last 50 years, as all studies have not looked at the type material in their revisionary research of the genus or the family.  In this study we propose an epitype for P. squamaria based on a modern concept of the species utilizing anatomical and rbcL sequence data.  We furthermore clarify the nomenclatural status of Sonderophycus and Sonderopelta which have been classified as genera within the Peyssonneliaceae.
