Addendum to the synoptic review of red algal genera

Abstract

An addendum to Schneider and Wynne's A synoptic review of the classification of red algal genera a half century after Kylin's ''Die Gattungen der Rhodophyceen'' (2007; Bot. Mar. 50: 197-249) is presented, with an updating of names of new taxa at the generic level and higher. In the last few years, the names of several new orders and families of red algae have been validated; these are cited and referenced below.

Second addendum to the synoptic review of red algal genera

“…The same format that was employed in the previous synoptic review and the first addendum Wynne 2007 , Wynne andSchneider 2010 ) is followed in this second addendum. All the genera established after Kylin (1956) and added here have the authorities who described them, as well as the year and page of the protolog printed in bold face along with the proper names.…”

“…The " References " section contains the literature cited for the protologs of the genera since Wynne and Schneider (2010) , as well as that not covered by Kylin (1956) and Schneider and Wynne (2007) .…”

“…Phylum Rhodophyta Subphylum Rhodellophytina Class Rhodellophyceae Order Dixoniellales Family Dixoniellaceae Note: Wynne and Schneider (2010) considered this family a synonym of the Glaucosphaeraceae based upon the rule of nomenclatural priority. Since then, however, the Glaucosphaeraceae was emended by Scott et al (2011Scott et al ( , 2012 to include only Glaucosphaera and transferred to the new order Glaucosphaerales [below].…”

“…cons. Note: Several genera have, over the years, been subsumed under the speciose Porphyra Wynne 2007 , Wynne andSchneider 2010 ). With the advances of molecular genetics in taxonomy, the workers have begun to find distinctions of the species at the generic level, and two genera (see below) with a large number of taxa have been resurrected for the genetic groupings that segregate them from Porphyra (Sutherland et al 2011 ).…”

“…Such molecular-based phylogenies often have shown the need to recognize segregate entities, at times necessitating the description of new genera or the resurrection of older generic names that had come to be treated as taxonomic synonyms using criteria based on the classical morphology and reproduction. Following the publication of Schneider and Wynne ' s (2007) " Synoptic review … of red algal genera, " and our first addendum to it (Wynne and Schneider 2010 ), additional changes have appeared, leading us to issue this second addendum. Furthermore, we continue to find obscure valid names that we had overlooked in the synoptic review.…”
