Surprising discovery of <i>Sedecula pulvinata</i> in Central Europe – is it really a species endemic to the western USA?
Bibliographic record
Abstract
Sedecula pulvinata ( Basidiomycota : Boletales ) is a hypogeous fungus reported as a rare and endemic species in the dry conifer forests of the western United States. Surprisingly, fruitbodies found in the Czech Republic, Central Europe, in 2011 match this species based on ITS rDNA sequences (99.3% sequence similarity) and morphology. Additional records attributable to this species based on sequence similarity were found in the GlobalFungi database of environmental metabarcoding data. This search expands the currently known geographical range in the western USA and adds new records from one Canadian and one Pakistani environmental DNA soil sample. These records challenge the assumption of its endemicity in the western United States. The European find, along with some from the USA and one from Canada, which significantly differ in habitat, suggests a broader ecological flexibility of this species. Further investigations are needed to determine the relationships between North American and European populations. Additionally, historical records and potential synonymy with other fungal species from Europe warrant further research into the taxonomy and systematics of this genus and related taxa.

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.
