Rediscovery of the vesicles that characterized <i>Rhizopogon vesiculosus</i>
Bibliographic record
Abstract
Molecular distinction between Rhizopogon vinicolor and R. vesiculosus has been made recently, but the diagnostic "yellow-brown (fresh) inflated cells" of R. vesiculosus, originally described by AH Smith, were not observed. These distinctive hyphal cells (vesicles) have not been reported since the type description. In that description they were said to collapse upon drying and described as being difficult to find. Here we report the rediscovery of these vesicles and describe their specific location on sporocarps of R. vesiculosus. We also report an original discovery that coiled, dark-walled hyphae on the sporocarps and in the mycorrhizae of R. vinicolor are of taxonomic value. The coiled hyphae, combined with the presence or absence of the elusive vesicles, allow R. vesiculosus and R. vinicolor to be morphologically distinguished with increased accuracy.

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.
