Using sequences of 5′ region of the cytochrome oxidase subunit 1 gene, large subunit rDNA, and ribulose‐1,5‐bisphosphate carboxylase/oxygenase large subunit gene as genetic markers to elucidate their phylogenetic positions, six unknown species from Western Australia, Tasmania, Lord Howe Is., and Norfolk Is. cluster with Meredithia in the Kallymeniaceae (Gigartinales), and are described as new members of this previously monospecific genus. Specimens from Bermuda referable to Kallymenia… 

Diversity of Kallymeniaceae (Gigartinales, Rhodophyta) associated with Hawaiian mesophotic reefs

This study provides additional evidence of the extent of diversity in the Kallymeniaceae that is poorly characterized from mesophotic depths and provides further evidence that members of the macroalgal flora contain overlooked biodiversity.

Neither Callophyllis nor Gelidium: Blastophyllis gen. nov. and Zuccarelloa gen. nov. (Kallymeniaceae, Rhodophyta) for three New Zealand species

Study of New Zealand Kallymeniaceae has revealed a great deal of diversity, providing new perspectives on relationships within the family and necessitating the establishment of new genera, including Zuccarelloa, which was established to accommodate a peculiar species mistakenly referred to the genus Gelidium, as Gelidium ceramoides.

Collections from the mesophytic zone off Bermuda reveal three species of Kallymeniaceae (Gigartinales, Rhodophyta) in genera with transoceanic distributions

A molecular survey of red algae collected by technical divers and submersibles from 90 m in the mesophotic zone off the coast of Bermuda revealed three species assignable to the Kallymeniaceae, one of which represents a deep water western Atlantic species now moved to an Australasian genus.

Verifying a new distribution of the genus Amalthea (Halymeniales, Rhodophyta) with description of A. rubida sp. nov. from Korea

A new species of Amalthea from Korea, Amal thea rubida sp.

Cryptic species diversity of the red algal genus Callophyllis (Kallymeniaceae, Gigartinales) from Korea

The species boundary of Callophyllis from Korea and Japan will be a cornerstone to revealing the phylogenetic affinity of the genus distributed in both hemispheres of the western Pacific.

Phylogenetic Analyses Support Recognition of Ten New Genera, Ten New Species and 16 New Combinations in the Family Kallymeniaceae (Gigartinales, Rhodophyta)

The most detailed multigene phylogenetic assessment of the red algal family Kallymeniaceae to date emphasising the floras of Australia, Europe and North America is presented and the need for considerably more taxonomic investigation in this diverse family is demonstrated.

A contaminant DNA barcode sequence reveals a new red algal order, Corynodactylales (Nemaliophycidae, Florideophyceae)

Generating genomic data from the host and associated epiphytic flora, and subsequently subtracting out genes of the former, facilitated a multigene phylogenetic analysis supporting recognition of Corynodactylaceae fam.

Notes on the benthic marine algae of Puerto Rico, XI: new records including new Meredithia (Kallymeniaceae, Rhodophyta) species

Abstract Continued collection of algae around the island of Puerto Rico principally focused on deep and shallow coral reef habitats led to the additional recognition of nine species previously

Notes on the marine algae of the Bermudas. 14. Five additions to the benthic flora, including a distinctive second new species of Crassitegula (Rhodophyta, Sebdeniales) from the western Atlantic Ocean

Abstract: A new red algal species, Crassitegula laciniata (Sebdeniaceae, Sebdeniales), was described from recent collections made on offshore Bermuda reef habitats, and it was distinguished

Could marine animal conservation laws be responsible for the decline or extirpation of macroalgal populations in Bermuda over the past century?

It is suggested that several large and abundant Bermuda macroalgal species recorded in the early 20th century appear to have been extirpated or are greatly diminished in sizes of individuals as well as population abundance, and proposed that marine animal protections over the past 35 years are a possible reason for the changes presently observing.



Psaromenia (Kallymeniaceae, Rhodophyta): a new genus for Kallymenia berggrenii

Molecular sequence analyses have shown that Kallymenia berggrenii, a species endemic to New Zealand, is more closely related to other taxa in the family Kally meniaceae than to the type species and other members of the genus Kally Menia.

Using molecular data to resolve the taxonomic limits of the genera Callophyllis, Euthora and Pugetia (Kallymeniaceae, Rhodophyta)

Phylogenetic analyses based on sequences of nuclear large‐subunit ribosomal DNA for representatives of the Kallymeniaceae were completed to assess the various taxonomic proposals surrounding Callophyllis, Euthora and Pugetia and indicate that the genus CallophyLLis (as generally recognized) is polyphyletic.

An examination of the red algal genus Pugetia (Kallymeniaceae, Gigartinales), with descriptions of Salishia firma gen. & comb. nov., Pugetia cryptica sp. nov. and Beringia wynnei sp. nov.

The red algal genus Pugetia was surveyed along the west coast of Canada using the DNA barcode (COI-5P – 5′ region of the mitochondrial cytochrome c oxidase I gene) as a species identification tool and subsequently resolved as five genetic species groups, although only two are reported in the flora.

A comparison of two DNA barcode markers for species discrimination in the red algal family Kallymeniaceae (Gigartinales, Florideophyceae), with a description of Euthora timburtonii sp. nov.

The results indicate that COI-5P is a more sensitive marker for delimiting species, but that it can be difficult to acquire clean amplification products for many isolates of Kallymeniaceae, owing to biological contami- nation.

A morphological and molecular assessment of the genus Sinotubimorpha (Halymeniaceae, Rhodophyta)

A critical reassessment of the morphological features of two closely related red algal genera, Grateloupia C. Agardh and Sinotubimorpha W. X. Ding, found that it was difficult to draw a clear‐cut distinction between the two genera based only on morphological differences.

Molecular support for the establishment of the new genus Laurenciella within the Laurencia complex (Ceramiales, Rhodophyta)

The phylogenetic position of this group, combined with the high genetic divergence from Laurencia s.s. (8.2–11%), strongly support the establishment of a sixth genus for the complex, proposed here as Laurenciella gen. nov.

The taxonomy, morphology and distribution of species of Scinaia Biv.-Bern. (Nemaliales, Rhodophyta) in north-western Europe

Meredithia microphylla is found on subtidal rock overhangs in the north-eastern Atlantic and in the Mediterranean and an account of the morphology of male and female reproductive organs is given for the first time from field material.

New Records of Marine Algae from Jeju Island, Korea

Five species of red algae were recorded for the first time in Korea: Acrochaetium plumosum, Gelidium australe, gelidium galapagense Taylor, Cryptonemia lactuca, Kallymenia harveyana, and Gelidium Australe.

The morphology and taxonomy of Australian Kallymeniaceae (Rhodophyta)

An account is given of the family Kallymeniaceae (Rhodophyta) on southern and eastern Australian coasts and of the genus Austrophyllis, which is similar in habit and structure to Callophyllis but differs in having distinct auxiliary cell systems.
