Vaucheria macounii comb. et stat. nov. (Vaucheriaceae, Xanthophyceae): first occurrence in Europe and notes on the species
Bibliographic record
Abstract
The article provides data on the first occurrence of Vaucheria longicaulis var. macounii Blum (Vaucheriaceae, Xanthophyceae) from the White Sea, an internal sea in northern European Russia. Originally described from the Pacific coast of the USA (Washington), the variety was subsequently found only in British Columbia, Canada. In 2021, the alga was first found in three localities on the northern coast of the Onega Peninsula. In 2022, it was found throughout collections from the eastern coast of the Onega Bay, indicating its much wider distribution. These records are considered the first in Russia, Europe, and the Arctic Ocean. The observations allowed the expansion of the morphological range of the variety in terms of shape and dimensions of gametangia. Due to significant differences in the shape and length of antheridia from the nominate variety of V. longicaulis, the raising of the variety to species level, as V. macounii, is proposed here.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
