Abstract: This study evaluated the species level taxonomy and phylogenetic relationships among species of the section Setacea of the genus Batrachospermum. Molecular data (sequences of the plastid-encoded RuBisCO large subunit gene, rbcL; and the barcode region of the mitochondrial gene that encodes the cytochrome c oxidase subunit 1, cox1) were generated and morphological characters described for 15 populations from Brazil, Japan and Spain. The analyses of rbcL sequences revealed that section… 
A new genus, Volatus and four new species of Batrachospermum sensu stricto (Batrachospermales, Rhodophyta)
TLDR
The new genus Volatus shares the distinctive characteristic of twisted or curled carpogonium-bearing branches with Kumanoa and Tuomeya but was not sister to either of these genera, suggesting that this character may have arisen at least three times in the order.
Revision of Batrachospermum section Macrospora (Batrachospermales, Rhodophyta) with the establishment of the new genus Montagnia
TLDR
Within the new genus, Montagnia is proposed, the characters used to circumscribe species were re-evaluated by examining type specimens as well as samples from North and South America, and species delimitation methods did not suggest that more than one species is justified.
Paludicola gen. nov. and revision of the species formerly in Batrachospermum section Turfosa (Batrachospermales, Rhodophyta).
TLDR
Substantial genetic variation within the Batrachospermales genus was discovered and 12 species are recognized based on DNA sequence data as well as morphological characters and geographic distribution.
First record of Nocturama (Batrachospermales, Rhodophyta) in South America, with the description of a new species N. novamundensis
TLDR
Comparison of DNA sequences of the plastid-encoded ribulose-1,5-bisphosphatecarboxylase–oxygenase large subunit and the nuclear small subunit ribosomal DNA markers showed Nocturama as a well supported clade, and Morphological and molecular evidence support recognizing the Brazilian specimens as a new species.
Revision of Batrachospermum Section Virescentia (Batrachospermales, Rhodophyta) with the Establishment of the New Genus, Virescentia Stat. nov.
TLDR
Five species of Batrachospermum section Virescentia are recognized and a new species is proposed as follows and the characters used to circumscribe species are re-evaluated by reexamination of type specimens and new collections in historically important areas.
Phylogenetic, evolutionary, and biogeographic origin of the genus Sheathia (Batrachospermales, Rhodophyta)
TLDR
Molecular sequences of rbc L, COI-5P, and psb A were used to investigate the phylogenetic, evolutionary, and biogeographic origin of the genus Sheathia, and three molecular markers supported that the two gametophyte stage specimens belong to S. longipedicellata.
Diversity of Batrachospermales (Rhodophyta) in the Iberian Peninsula
TLDR
Seven taxa reported in the region using current taxonomy are confirmed with sequence data and morphology, and biogeographic trends show a flora with most species being well represented in parts of Europe, two taxa that are shared between Europe and North America, and one cosmopolitan species.
Current status of freshwater red algal diversity (Rhodophyta) of the African continent including description of new taxa (Batrachospermales)
TLDR
It is estimated that 14 to 19 batrachospermalean taxa can be recognised for the African flora, and that with more study, that number could easily double or triple based on the diversity known from other well-studied continents.
Phylogeography of the freshwater red alga Setacea puiggariana (Rhodophyta, Batrachospermales) in Brazil
TLDR
This study confirmed the general pattern found in Batrachospermales: that little variation is typically observed within a location and that most populations have one, rarely two haplotypes, and found no evidence of higher genetic divergences with increased geographic distance among haplotypes.
Kumanoa chaugulei (Batrachospermales, Rhodophyta), a new species of freshwater red algae from the Western Ghats, India
TLDR
Kumanoa chaugulei is described from Idamalayar, a major tributary of Periyar River flowing through the state of Kerala, India, based on morphological and molecular evidence and is likely to be endemic to the Western Ghats.

PHYLOGENY OF THE BATRACHOSPERMALES (RHODOPHYTA) INFERRED FROM rbcL AND 18S RIBOSOMAL DNA GENE SEQUENCES
The sequence data from the large subunit of ribulose‐1,5‐bisphosphate carboxylase/oxygenase (rbcL) gene and 18S ribosomal DNA (small subunit) of taxa in the freshwater rhodophyte order
INSIGHTS INTO THE PHYLOGENY OF THE BATRACHOSPERMALES (RHODOPHYTA) FROM rbcL SEQUENCE DATA OF AUSTRALIAN TAXA
TLDR
A phylogenetic analysis of RUBISCO large subunit (rbcL) gene sequence data revealed three clades of batrachospermalean taxa: a “mixed” clade composed of taxa sampled from Australia and North America, a clade of primarily Australian collections, and aClade of predominantly North American samples.
Molecular and morphological evidence for Sheathia gen. nov. (Batrachospermales, Rhodophyta) and three new species
TLDR
It is found that heterocortication, the presence of both cylindrical and bulbous cells on the main axis, is an underlying synapomorphy of this clade Batrachospermum section Helminthoidea.
MOLECULAR PHYLOGENY OF THE GENUS KUMANOA (BATRACHOSPERMALES, RHODOPHYTA) 1
TLDR
The phylogenetic analyses did not reveal any interpretable biogeographic patterns within the genus Kumanoa, and no intrageneric classification is recommended based on current knowledge.
Investigation of two species complexes in Batrachospermum section Batrachospermum (Batrachospermales, Rhodophyta)
TLDR
Evidence is provided that section Batrachospermum will need to be split with the potential of resurrecting section Helminthoidea and that the generic classification needs revision.
Phylogenetic relationship of Batrachospermum species (Batrachospermales, Rhodophyta) from coastal streams in French Guiana
TLDR
Batrachospermum turfosum is the only species presently sequenced from section Turfosa and these samples formed a well-supported clade on a long branch, which was variously related to other batrACHospermalean taxa in the analyses.
SYSTEMATICS OF THE BATRACHOSPERMALES (RHODOPHYTA)—A SYNTHESIS 1
TLDR
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.
Biogeographical analyses of Batrachospermum helminthosum (Batrachospermales, Rhodophyta) in North America using molecular and morphological data
TLDR
Analysis of morphometric characteristics showed the species to be morphologically plastic across its range, with samples from distant locations being genetically similar.
Contrasting intra versus interspecies DNA sequence variation for representatives of the Batrachospermales (Rhodophyta): Insights from a DNA barcoding approach
TLDR
A number of batrachospermalean taxa worthy of more detailed DNA barcode study are revealed, and it is predicted that such research will have a substantial effect on the taxonomy of species within the BatrachOSpermales in the future.
