Phaeocollybia in western North America. I. The<i>Phaeocollybia kauffmanii</i>complex
Bibliographic record
Abstract
Morphological and molecular investigations during a taxonomic reevaluation of the genus Phaeocollybia revealed four new agaric species from British Columbia, Washington, Oregon, and California that are morphologically similar to Phaeocollybia kauffmanii (Smith) Singer. All five species produce large basidiomes with brown pilei, stipes with cartilaginous rinds surrounding dense pith, vertical-monopodial pseudorhizae, large, verrucose or verruculose, apically beaked basidiospores, and thin-walled, clavate cheilocystidia. The most salient morphological characters distinguishing the new species from P. kauffmanii include abundant clamp connections (Phaeocollybia ammiratii), a pink- or purple-brown pileus lacking encrusting pigments in the pileipellis (Phaeocollybia benzokauffmanii), a nonviscid, fibrillose, ochraceous pileus with a trilaminate pileipellis (Phaeocollybia luteosquamulosa), and unusually large basidiospores and subglobose subcapitate pedicellate cheilocystidia (Phaeocollybia redheadii). An emended description of P. kauffmanii accompanies technical descriptions and a key to the five species and newly revealed complex.Key words: Agaricales, Basidiomycota, Cortinariaceae, RFLPs, temperate rainforest.

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.
