A new species of <i>Lactarius</i> sect. <i>Deliciosi</i> (Russulales, Basidiomycota) from western North America
Bibliographic record
Abstract
Although Lactarius sect. Deliciosi (Fr.) Redeuilh, Verbeken & Walleyn (syn. Lactarius sect. Dapetes) is a readily identifiable group in the field, it is exceedingly difficult to correctly identify species with orange to reddish orange latex. A lack of careful study of these species in North America in general, and the Pacific Northwest more specifically, makes species identification often impossible. One common undescribed Pacific Northwest species, which begins fruiting rather early in the season, is described here as Lactarius aestivus sp. nov. It is found in conifer forests dominated by Abies Mill. and Tsuga Carrière, and is characterized by bright orange latex and zonate, bright to pale orange pileus that only rarely stains greenish. A phylogenetic analysis based on ITS sequences supports the species delimitation.
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.
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; both teacher heads agree on what is shown here.
