Taxonomy of Ophiostoma radiaticola sp.nov. (Ophiostomatales, Ascomycetes), the teleomorph of Pesotum pini, isolated from logs of Pinus radiata
Bibliographic record
Abstract
A new Ophiostoma species causing sapstain was isolated from Pinus radiata logs grown and stored in New Zealand, and imported from New Zealand to Korea.Ophiostoma radiaticola produces dark ascomata with long necks, lacks ostiolar hyphae and has hyaline reniform ascospores with a hat-shaped sheath.The fungus has mononematous Leptographium-like conidiophores that intergrade with synnematous Pesotum-like conidiophores, the latter previously described under the anamorph name Pesotum pini Mating tests on pine sapwood wafers demonstrated that O. radiaticola is a heterothallic species with two mating types.Phylogenetic analyses of aligned ITS 2/partial LSU rDNA, partial B-tubulin and partial actin DNA sequences demonstrate that O. radiaticola is a phylogenetically distinct species most closely related to O. cainii and O. galeiformis, with which it shares many morphological characters.It is also more closely related to Ophiostoma species with Leptographium anamorphs than to species of the O. piceae and O. ulmi complexes, the best-known groups of species with Pesotum anamorphs.
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.
