<i>Cortinarius parkeri</i>, a new species from the Pacific Northwest of North America
Bibliographic record
Abstract
Cortinarius parkeri , a new vernal species in subgenus Cortinarius , section Veneti , is described from the Pacific Northwest of North America. Within its subgenus, C. parkeri is unique in that its membranous universal veil is attached to the pileus edge of young mushrooms and extends as a covering over the pileus surface. At maturity, the universal veil forms a sheathing membranous volva-like structure that flares out above the stipe base. Sequences of the nuclear ribosomal DNA internal transcribed spacer region (ITS1-5.8s-ITS2) determined for 13 collections of C. parkeri were all identical, except for a polymorphic two base pair indel. In a phylogeny including other related species from North America and Europe, C. parkeri is monophyletic. In contrast to intraspecific distances, the interspecific genetic distance between C. parkeri and other Veneti species sequences was large. Being dikaryotic, mushrooms of C. parkeri contain genomes from two parents. As expected in a dikaryon in an interbreeding population, the polymorphic indel was homozygous in some collections but heterozygous in three collections, with conflicting sequences resulting from mixed parental types. Taken together, morphological and molecular results strongly support C. parkeri as a new and distinctive species.

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.
