Abstract
Delamarea attenuata (Kjellman) Rosenvinge is a species of brown algae restricted to cold waters of the North Atlantic and the North Pacific. This monotypic genus is distinguished by its unbranched cylindrical parenchymatous axes with a surface layer of large, loosely connected vesicular pigmented cells called paraphyses (Hariot 1889; Kawai and Kurogi 1980; Rosenvinge and Lund 1947). Ovate unilocular sporangia or elongate plurilocular sporangia are typically produced on separate thalli but sometimes on the same thallus (Pedersen 1984). The family Delamareaceae has been recognized by Zinova (1953), primarily on the unique structure of the paraphyses. The order Delamareales was established by Lund (1959), but Pedersen (1974, 1984) argued against ordinal recognition, placing the Delamareaceae within the Dictyosiphonales. Evidence from gene-sequencing analyses, which have included Delamarea, currently places the Dictyosiphonales within a broadly circumscribed Ectocarpales (Draisma et al. 2001). This note is to point out that an error has persisted in the literature regarding the alleged occurrence of this distinctive species in New England (Guiry and Guiry 2007; Sears 1998, 2002; Taylor 1957). Taylor (1957) reported it to occur from both ‘‘southern Massachusetts and Ile Miquelon’’ off the south coast of Newfoundland. The latter location is correct in that Hariot (1889) first described Delamarea from there (as D. paradoxa Hariot). Later, Rosenvinge (1893) recognized that Kjellman’s (1883) Scytosiphon attenuatus, described from Spetsbergen, was a taxonomic synonym that had priority over Hariot’s binomial. Taylor’s (1957) record of Delamarea attenuata from Massachusetts is here questioned. Taylor cited Doty’s (1948) report of Scytosiphon attenuatus from Woods Hole, Massachusetts.

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.
