The informal “Australasica Group” was established in 2009 to include several Australasian endemic Batrachospermum species, a few species of the cosmopolitan Batrachospermum section Setacea, and the South American endemic Petrohua bernabei. Although useful for communication purposes, no formal taxonomic designation was proposed due to weakly supported basal nodes. The present research took a two‐pronged approach of adding more taxa (29 additional specimens) as well as more sequence data (LSU… 
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 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.
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.
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 the Genus Sirodotia Kylin (Batrachospermales, Rhodophyta) with Description of Four New Species
TLDR
Phylogenetic analyses showed the genus Sirodotia Kylin to be a monophyletic lineage with high support and the following morphological characters were applied to distinguish species: primary fascicle cell number, spermatangial arrangement, origin of gonimoblast filament and size of carposporangia.
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 B atrachospermum viride‐brasiliense (Rhodophyta, Batrachospermales)
TLDR
The trend observed in this study is similar to that in other members of Batrachospermales with little variation within a stream segment (one or two haplotypes) and more distant haplotypes showing higher divergences.
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.
The freshwater red algae (Batrachospermales, Rhodophyta) of Africa and Madagascar I. New species of Kumanoa, Sirodotia and the new genus Ahidranoa (Batrachospermaceae)
TLDR
Four new species and one new genus of freshwater red algae from the Batrachospermales are described, based on morphological and molecular evidence, among the first new descriptions since 1899 from the African continent and since 1964 from Madagascar.
Revealing hidden diversity in the Sheathia arcuata morphospecies (Batrachospermales, Rhodophyta) including four new species
TLDR
Revealing hidden diversity in the Sheathia arcuata morphospecies (Batrachospermales, Rhodophyta) including four new species is revealed.

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.

A New Species of Kumanoa (Batrachospermales, Rhodophyta) from Kōke‘e State Park, Kaua‘i, Hawai‘i1
TLDR
Phylogenetic analyses support K. alakaiensis as a distinct and early diverging lineage within the genus Kumanoa, and as sister to a large clade containing all but three species characterized to date.
Large subunit rDNA and rbcL gene sequence data place Petrohua bernabei gen. et sp. nov. in the Batrachospermales (Rhodophyta), but do not provide further resolution among taxa in this order
TLDR
The results showed that the new entity with pseudoparenchymatous tube morphology is a member of the Batrachospermales and Petrohua bernabei gen. et sp.
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.
Batrachospermum pseudogelatinosum (Batrachospermales, Rhodophyta), a polyecious paraspecies from Australia and New Zealand
TLDR
The acceptance of a broadly circumscribed paraphyletic species (paraspecies), B. pseudogelatinosum, which includes both dioecious and monoecious populations is recommended, which is no better or worse than any other taxonomic character.
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.
Batrachospermum (Batrachospermales, Rhodophyta) in Australia and New Zealand: new taxa and emended circumscriptions in sections Aristata, Batrachospermum, Turfosa and Virescentia
TLDR
Fifteen species of Batrachospermum from Australia and New Zealand are documented, including (except for the recently described B. antipodites Entwisle) descriptions, photomicrographs, maps and keys, with many of the new taxa difficult to allocate in the existing sectional system.
