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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
