“…Distance between lineages ranged from 0.3 to 2.2% for UPA, 0.8 to 4.1% for rbcL, and 3.2 to 9.0% for COI-5P. Similar values have been reported for UPA (e.g., Clarkston & Saunders 2012), rbcL (e.g., Gabriel et al 2009), and COI-5P (e. g., Le Gall & Saunders 2010) between species of other red algal genera. The exception observed for COI-5P, with genetic divergences within lineage B above 0.75%, has also been reported for other taxonomic groups (e.g., 2.86% for Callophyllis edentata Kylin 1925: 34 (Clarkston & Saunders 2013.…”

“…Phylogenetic assessments of other members of the family that included Gibsmithia hawaiiensis and G. dotyi suggested the monophyly of the genus (Sherwood et al 2010;Clarkston and Saunders 2012).

Gibsmithia hawaiiensis is a peculiar red alga characterized by furry gelatinous lobes arising from a cartilaginous stalk. The species has been recorded from tropical reef systems throughout the Indo-Pacific. A multilocus phylogeny (UPA, rbcL, COI-5P) of 36 specimens collected throughout the species distribution range, showed high genetic diversity at species level. Two major groups were identified, each consisting of multiple lineages. Genetic variability was low in the Hawaiian Islands and the northern Red Sea and high in the Western Indian Ocean and the Coral Triangle, where lineages overlap in distribution. Genetic distances suggest that G. hawaiiensis represents a complex of five cryptic species, with no difference observed in the external morphology corresponding to separate lineages. Anatomical and reproductive differences were observed at the microscopic level for the lineage from the Red Sea, which is here described as G. eilatensis sp. nov. The geographic range of the species complex is here expanded to include Madagascar, the Red Sea and the Indo-Malay region, and the generitype seems endemic to the Hawaiian Islands. Algal diversity on coral reef systems is discussed from a conservation perspective using G. hawaiiensis as an example.

Twenty-five specimens of the freshwater red alga Compsopogon were collected from locations in North America, South America, Europe, Asia, Australasia and Oceania, and from an aquarium, with the goal of determining genetic diversity among specimens and ascertaining the number of phylogenetic species. Specimens were morphologically identified as having either the 'caeruleus' morphology, with regular polyhedral cortical cells, or the 'leptoclados' morphology, with irregular cortical cells with rhizoidal outgrowths. The 'leptoclados' morphology has been used by some researchers to distinguish the genus Compsopogonopsis from Compsopogon, or at least to distinguish C. leptoclados from other Compsopogon species. Sequence data for the rbcL gene and cox1 barcoding region were obtained for most specimens. In addition, SSU and partial LSU (barcode) rDNA were explored for a few specimens, but all sequences were identical. For the 25 newly generated and eight previously published rbcL gene data, there were seven unique haplotypes, but the sequence divergence was very low (≤7 bp, ≤ 0.7%). One haplotype was widespread, represented by 21 specimens from diverse locations in all regions sampled. Likewise, the 22 new and one previously published cox1 barcode region sequences yielded seven unique haplotypes with little sequence divergence (≤13 bp, ≤ 2.0%). One haplotype was widespread, being shared among 16 specimens from all regions. The combined molecular and morphological data showed no genetic differentiation between the 'caeruleus' and 'leptoclados' morphologies. The ubiquitous distribution of Compsopogon in tropical/subtropical regions and its low genetic variation are probably facilitated by the alga's ability to tolerate a wide range of stream conditions and its propagation via asexual spores. Given the findings of previous culture-based studies, morphometric research and field observations, coupled with the results of our study, we conclude there is only a single monospecific genus worldwide and that the species is correctly called C. caeruleus, since this is the oldest validly published name; all other previously described species of Compsopogon and Compsopogonopsis are synonyms.

“…Note: Based upon the multigene analyses, Clarkston and Saunders (2012) placed Beringia , Erythrophyllum , Kallymeniopsis , and Hommersandia in the Kallymeniaceae rather than the Crossocarpaceae where they previously had been treated. Guiry et al (in Guiry , 2012 ) described this new family, based on the genus Schmitziella , and provisionally assigned it to the order Gigartinales.…”

Abstract:A second addendum to Schneider and Wynne ' s (Schneider, C.W. and M.J. Wynne. 2007. A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Bot. .) " Synoptic review " of red algal genera and their classification is presented, with an updating of names of new taxa at the generic level and higher. In the past few years, the hierarchy of some genera has changed due to new subfamilies, which are cited and referenced below. There have also been the descriptions of some higher taxa in the past few years.
