Abstract
Lentinula edodes is among the five globally cultivated edible mushrooms, which are wood decaying spore bearing Basidiomycetes possessing separate hyphae. Specific identification of this fungus from others in the division Basidiomycota using specific primers enables a fast and accurate detection through polymerase chain reaction (PCR). As a prelude to additional nutritional and sequence characterization research, we have developed a species-specific PCR assay for this fungus after screening four primer-pairs and two universal primer pairs. The primer-pair LE1F/R was specific in amplifications of ATCC-defined L. edodes strains and did not amplify DNA from six medicinally and nutritionally important fungal reference strains, Oyster (Pleurotus ostreatus), Maitake (Grifola frondosa), Enoki (Flammulina velutipes), Baby bella (Agaricus bisporus), Porcini (Boletus edulis), and Chanterelle (Cantharellus cibarius). However, amplifications using the universal primers were positive for all six strains. This assay will therefore serve to validate morphology-based-identifications of L. edodes strains. Key words: Lentinula edodes, LE1F/R, species-specific primers.

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 it
