Ergot fungus<i>Claviceps cynodontis</i>found on Bermuda grass (<i>Cynodon dactylon</i>) in the Americas
Bibliographic record
Abstract
Claviceps cynodontis is a widespread parasite of Cynodon spp. (Bermuda grass) in the paleotropical and subtropical regions. The sphacelial stage of ergot on Cynodon dactylon in México and Texas was identified as that of Claviceps cynodontis by comparison of conidial morphology, rDNA sequence, and random amplified polymorphic DNA (RAPD) patterns with an African isolate of this species. Sequence of internal transcribed spacers ITS1-5.8S-ITS2 of Claviceps cynodontis clustered phylogenetically with those of Claviceps maximensis, Claviceps rhynchelytri, and Claviceps sp. SG (from Setaria geniculata). This is the first record of the identification of Claviceps cynodontis in the Americas.
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.
