<i>CHUKCHIA PEDICELLATA</i> GEN. ET SP. NOV. AND <i>C. ENDOPHYTICA</i> NOV. COMB., ARCTIC ENDEMIC BROWN ALGAE (PHAEOPHYCEAE)<sup>1</sup>
Bibliographic record
Abstract
Study of the north Alaskan brown algal epiphyte Chukchia pedicellata sp. nov. suggests an apparently close relationship to Phaeostroma. Phaeostroma endophyticum S. Lund from east Greenland, Bylot Island, Nunavut, Canada, shows generic identity with Chukchia and specific differences from C. pedicellata. Comparison of C. pedicellata and P. pustulosum Kuck. (the type species of Phaeostroma) shows morphological, cytological, reproductive, and distributional differences. We recognize novelty of C. pedicellata and necessity to broaden the species description of P. endophyticum, which becomes Chukchia endophytica. C. endophytica is distinguished by its dimorphic vegetative habit, its large plurilocular sporangia, and the putative ability of the sporangia to digest host tissue to accommodate development within the host. Absence of pyrenoids and novel plurilocular sporangia in both species suggests that they are not members of the Ectocarpales, sensu lato.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
