Intercontinental distributions of species of <i>Cortinarius</i>, subgenus <i>Phlegmacium</i>, associated with <i>Populus</i> in western North America
Bibliographic record
Abstract
Three species of Cortinarius subg. Phlegmacium, Cortinarius argutus Fr. and Cortinarius hedyaromaticus C. Cripps & O.K. Mill. (section Arguti stat. nov.) and Cortinarius talus Fr. (section Multiformes), are compared from western North America and Europe. Phylogenetic analysis of the ITS region shows that C. argutus and C. hedyaromaticus are separate, closely related species with rooting stipes. Cortinarius talus is a pale species with a bulbous stipe and a sweet odor similar to that of C. hedyaromaticus; C. argutus lacks this sweet odor. All three species have intercontinental distributions and are associated with deciduous trees, primarily Populus tremuloides Michx., Populus tremula L., but also Salix spp. This study highlights the importance of the study of type specimens and molecular analysis to stabilize the application of established names.
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.
