This taxonomic synthesis increases the level of monophyly within the Batrachospermales but minimizes taxonomic change where data are still inadequate, resulting in a few relatively conservative taxonomic changes.
A molecular method for identification of the morphologically plastic invasive algal genera Eucheuma and Kappaphycus (Rhodophyta, Gigartinales) in Hawaii
Neighbor-joining analyses were congruent in their separation of Eucheuma and Kappaphycus, and the resulting clusters were consistent with those revealed for global comparisons with the mitochondrial cox2-3 spacer and GenBank data.
UNIVERSAL PRIMERS AMPLIFY A 23S rDNA PLASTID MARKER IN EUKARYOTIC ALGAE AND CYANOBACTERIA 1
The feasibility of amplifying and sequencing this marker across multiple algal lineages and the remarkable universality of these primers suggests potential for their use in assays of environmental samples in which they could be used to simultaneously detect a number of different algallineages.

Molecular data for the survey provide the most extensive assessment of Hawaiian red algal diversity and, in combination with the morphological/anatomical and distributional data collected as part of the project, provide a solid baseline data set for future studies of the flora.
Assessing the phylogenetic position of the Prasiolales (Chlorophyta) using rbcL and 18S rRNA gene sequence data
Parsimony and distance analyses of the rbcL and 18S rRNA sequences indicate that the Prasiolales is a well-defined order and provide moderate support for a relationship with the Trebouxiophyceae, which has been postulated in past studies based on cellular and ultrastructural characters.
MOLECULAR ASSESSMENT OF ULVA SPP. (ULVOPHYCEAE, CHLOROPHYTA) IN THE HAWAIIAN ISLANDS 1
It is suggested that Ulva populations in tropical and subtropical regions consist of species that are largely unique to these areas, for which the application of names based on types from temperate and boreal European and North American waters is inappropriate.
Morphology and phylogenetic position of Spongiochrysis hawaiiensis gen. et sp. nov., the first known terrestrial member of the order Cladophorales (Ulvophyceae, Chlorophyta).

Phylogenetic analyses of the 18S rRNA gene showed that Spongiochrysis hawaiiensis is a member of the freshwater clade of the Cladophorales/Siphonocladales lineage in the green algal class Ulvophyceae and can be considered as the first known successful step of a members of the order Cladphorales into terrestrial habitats.
A comparative analysis of COI, LSU and UPA marker data for the Hawaiian florideophyte Rhodophyta: Implications for DNA barcoding of red algae
A total of 290 florideophyte samples from the Hawaiian Rhodophyta Biodiver- sity Survey, spanning 17 orders of red algae, were sequenced for the mitochondrial COI DNA barcode, partial nuclear LSU rRNA gene, and plastid UPA rRNA marker, indicating that some phylogenetic utility can be gained from barcode-like sequences that are obtained for biodiversity surveys.
Phylogeography of Asparagopsis taxiformis (Bonnemaisoniales, Rhodophyta) in the Hawaiian Islands: two mtDNA markers support three separate introductions

Parsimony analyses of both regions for the Hawaiian collections revealed relationships that were consistent with those previously published for global A. taxiformis samples, and future studies may only need to sequence one of the two markers.
A PROPOSAL FOR A NEW RED ALGAL ORDER, THE THOREALES1
Findings indicate the Thoreaceae has been misclassified in the Batrachospermales and should be placed in its own order, theThoreales, characterized by having freshwater representatives with multiaxial gametophytes, a uniaXial chantransia stage, and pit plugs with two cap layers, the outer one of which is usually plate‐like.
