Ophiostoma breviusculum sp. nov. (Ophiostomatales, Ascomycota) is a new species in the Ophiostoma piceae complex associated with bark beetles infesting larch in Japan
Bibliographic record
Abstract
A new species of the Ophiostoma piceae-complex was isolated from bark beetles and the insect galleries of Larix kaempferi in Japan. This species was described as Ophiostoma breviusculum. The fungus was morphologically similar to O. piceae and O. quercus. However the average length of the perithecial necks and synnemata were shorter than for O. piceae and O. quercus. Synnemata morphological characteristics also differentiated O. breviusculum from the other species of the Ophiostoma piceae-complex isolated from conifers. Mating tests demonstrated that this fungus did not produce perithecia with O. floccosum, O. piceae and O. quercus. In phylogenetic trees using rDNA ITS O. breviusculum was placed in a clade with O. canum, O. piceae and O. subalpinum, but when using beta-tubulin it was placed into a separate clade.
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.
