Discovery and description of a teleomorph for Leptographium koreanum
Bibliographic record
Abstract
A Leptographium sp.unknown in Japan was isolated from Japanese red pine (Pinus densiflora) in this study.Pairing of different strains of the fungus gave rise to mature perithecia of an Ophiostoma sp.Characteristics of this teleomorph were similar to those of Ophiostoma piceaperdum, but the fungus had larger ascospores.The anamorph state had 2 to 3 primary branches, and was similar to Leptographium truncatum, L. yunnanense, L. pini-densiflorae, and particularly to L. koreanum.Comparisons of partial actin, -tubulin, and rDNA sequences data showed that the Japanese fungus is L. koreanum.Pairing of strains from Japan with the ex-type culture of L. koreanum gave rise to mature perithecia confirming this identification.The teleomorph of L. koreanum is thus described here as Ophiostoma koreanum.

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.
