Ophiostomatoid fungi isolated from<i>Pinus radiata</i>logs imported from New Zealand to Korea
Bibliographic record
Abstract
Ophiostomatoid fungi discolor lumber, logs, and tree sapwood. Stained wood has a lower market value and can be refused by importing customers because such products can potentially carry pathogenic fungi. Little information is available on the ophiostomatoid fungi that colonize Pinus radiata D. Don (radiata pine) logs imported from New Zealand into Korea. In this work, we attempted to identify the native and non-native fungi colonizing wood imported into Korea. At least 12 species of ophiostomatoid fungi, including an unknown Ophiostoma sp. A, were identified among the fungi-staining radiata pine. They were Leptographium procerum (Kendr.) Wingf., Leptographium bistatum Kim & Kim, Ophiostoma floccosum Mathiesen, Ophiostoma huntii (Rob.) Hoog & Scheff., Ophiostoma ips (Rumbold) Nannf., Ophiostoma nigrocarpum (David.) Hoog, Ophiostoma piceae (Münch) H. & P. Sydow, Ophiostoma piliferum (Fries) H. & P. Sydow, Ophiostoma quercus (Georgév.) Nannf., Ophiostoma radiaticola Kim et al., and Ophiostoma setosum Uzunovic et al. Of these species, O. floccosum was the dominant species in both logs and boards. We confirmed that many of the sapstain species that we isolated have been previously reported in Korea. However, four species, O. radiatcola, O. setosum, O. huntii, and O. nigrocarpum have not been reported previously in Korea. We also found the new species, L. bistatum, along with an unknown Ophiostoma sp. A.Key words: radiata pine, ophiostomatoid fungi, New Zealand, non-native organisms, β-tubulin gene.
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.

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.
