<i>PREDAEA LUCESCENS</i> SP. NOV., A NEW COOL‐TEMPERATE AUSTRALIAN SPECIES WITH UNIQUE, UNDIFFERENTIATED NUTRITIVE FILAMENTS
Bibliographic record
Abstract
The red algal genus Predaea (Schizymeniaceae, Gigartinales) includes approximately a dozen species of tropical and subtropical distribution. Plants are gelatinous in consistency, and the carpogonial branches and auxiliary cells are widely separated in female gametophytes (non‐procarpy). Predaea is distinguished from other red algal genera in possessing clusters of small rounded nutritive cells that are borne on the one proximal and distal two cells directly attached to the auxiliary cell. We describe a new species from cool‐temperate (10–18° C yearly range) southeastern Australia that, unlike the tropical and subtropical species, lacks the typical gelatinous texture and has dwarf vegetative filaments of normally contoured cells associated with the auxiliary cell rather than small clusters of spherical nutritive cells. Anatomical and molecular data are combined to postulate the phylogenetic affinities of the new species to others of the genus, to highlight relationships of Predaea to other genera of the Schizymeniaceae, and to consider this family relative to others now placed in the Gigartinales.

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.
