A multilocus phylogeny of <i>Hericium</i> ( <i>Hericiaceae, Russulales</i> )
Bibliographic record
Abstract
Clear distinction of the species of Hericium will aid in natural products discovery, medicinal applications, and breeding for commercial cultivation of these edible and medicinally valuable mushrooms. A phylogeny of Hericium species from North America, together with key taxa from Europe, was accomplished using sequence data from the nuclear ribosomal internal transcribed spacer (ITS) region and adjacent large ribosomal subunit (LSU), translation elongation factor 1-alpha ( TEF-1α ), and RNA polymerase second largest subunit ( RPB2 ) gene sequences. Compared to previous unresolved phylogenies based solely on ITS data, the species of Hericium were resolved as monophyletic groups, including the type species H. coralloides (synonyms and H. ramosum ; Europe and North America), H. alpestre (Europe to central Asia), H. americanum (eastern North America), H. abietis (western North America), H. cirrhatum (Europe and boreal-montane North America), H. erinaceus (Europe), two recently described species of the H. erinaceus species complex, H. asiaticum (Eastern Asia) and H. carolinense (eastern United States), and a third new species in this complex from western North America, H. oregonense described herein. All taxa, including the newly described species within the H. erinaceus complex, were strongly supported in maximum likelihood analyses.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
