A new order of red algae based on the Peyssonneliaceae, with an evaluation of the ordinal classification of the Florideophyceae (Rhodophyta)
TLDR
A new order, Peyssonneliales, is herein proposed to accommodate the Peysonneliaceae, with only two of the genera recognized, and its relationship to the other red algal orders is discussed.
Molecular diversity of the Caulerpa racemosa–Caulerpa peltata complex (Caulerpaceae, Bryopsidales) in New Caledonia, with new Australasian records for C. racemosa var. cylindracea
Sauvage T., Payri C., Draisma S.G.A., Prud′homme van Reine W.F., Verbruggen H., Belton G.S., Gurgel C.F.D., Gabriel D., Sherwood A.R. and Fredericq S. 2013. Molecular diversity of the Caulerpa
Taxonomic studies in the Schizymeniaceae (Nemastomatales, Rhodophyta): on the identity of Schizymenia sp. in the Azores and the generic placement of Nemastoma confusum
TLDR
Examination of type material of Nemastoma confusum indicates that this species should be transferred to the genus Platoma in the Schizymeniaceae, and secondary pit connections were observed in gametophytes of S. apoda from the Azores, a previously unknown character for the Nemastomatales.
Phylogenetic appraisal of the genus Platoma (Nemastomatales, Rhodophyta), including life history and morphological observations on P. cyclocolpum from the Azores
TLDR
Phylogenetic appraisal of the genus Platoma (Nemastomatales, Rhodophyta), including life history and morphological observations on P. cyclocolpum from the Azores, and phylogenetic relationships of four Platoma species are discussed.
A Dynamic Approach to the Study of Rhodoliths: A Case Study for the Northwestern Gulf of Mexico
Abstract In the northwestern Gulf of Mexico, beds of rhodoliths and unconsolidated rubble at 55–70 m depth are associated with unique offshore deep bank habitats known as salt domes or diapirs. Prior
Predaea feldmannii subsp. azorica (Nemastomataceae, Nemastomatales), a new subspecies of red algae (Rhodophyta) from the Azores
TLDR
A phylogenetic tree inferred from chloroplast-encoded rbcL sequences of selected members of the Nemastomatales is presented, finding that P. azorica shares with P. feldmannii linear-oblong outer cortical cells, dichotomously branched cortical fascicles, a large number of auxiliary nutritive cells per cluster, and gonimoblast initiation from the incoming connecting filament near its point of fusion with the auxiliary cell.
Beneath the hairy look: the hidden reproductive diversity of the Gibsmithia hawaiiensis complex (Dumontiaceae, Rhodophyta)
TLDR
The tropical alga previously recognized as Gibsmithia hawaiiensis (Dumontiaceae, Rhodophyta) was recently suggested to represent a complex of species distributed throughout the Indo‐Pacific Ocean and characterized by a peculiar combination of hairy (pilose) gelatinous lobes growing on cartilaginous stalks, indicating that the complex is more broadly distributed than previously considered.
Taxonomic transfer of the red algae Chrysymenia enteromorpha and C. wrightii to the genus Botryocladia (Rhodymeniaceae, Rhodymeniales)
TLDR
The results suggest that on the basis of vegetative characters alone, the true Chrysymenia clade contains specimens that exclusively produce gland cells directly on unmodified medullary cells, whereas Botryocladia and Cresia may or may not cut off gland cells from modified gland-supporting medullARY cells.
Multilocus phylogeny reveals Gibsmithia hawaiiensis (Dumontiaceae, Rhodophyta) to be a species complex from the Indo-Pacific, with the proposal of G. eilatensis sp. nov.
TLDR
A multilocus phylogeny of 36 specimens collected throughout the G. hawaiiensis distribution range, showed high genetic diversity at species level, and two major groups were identified, each consisting of multiple lineages.
