Morphological and molecular studies in the genus <i>Hypnea</i> (Rhodophyta) in Australia: <i>Hypnea decipiens sp. nov</i> . and <i>Hypnea subramentacea</i> sp. nov
Bibliographic record
Abstract
Molecular analyses (rbcL, COI-5P) of Australian specimens that had previously been identified as Hypnea musciformis based on morphology have revealed that this entity is not that species but rather represents an undescribed cryptic species that is here named Hypnea decipiens sp. nov. The new species is known from south-western and southern Australia, north to the Houtman Abrolhos (Geraldton region) of Western Australia and east to the Eyre Peninsula, South Australia. Plants can be locally common in the shallow subtidal and grow to 14 cm in height, with upper branches terminated by crozier-like hooks. Vegetative, cystocarpic and tetrasporangial plants are known, with the zonate tetrasporangia arising in nemathecia at the basal or median sections of lateral branchlets. Despite the morphological similarities, in phylogenetical analyses H. decipiens did not group with the H. musciformis complex (H. musciformis, H. pseudomusciformis, H. caraibica, H. schneideri), but rather was sister to the South African H. rosea. An additional new species, H. subramentacea sp. nov. is described for specimens from south-western Australia that were sister to the common H. ramentacea.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
