Medicinal mushroom <i>Agaricus subrufescens</i> from Iran shares genetic markers with specimens from China and Thailand
Bibliographic record
Abstract
Agaricus subrufescens Peck is a cosmopolitan species of nutritional and medicinal interest. Three types of internal transcribed spacer (ITS) rDNA sequences were recently characterized for this species. Sequences of types A, B, or both types A and B are found in American and European specimens, while sequences of type C are found in Asian (China and Thailand) and Oceanian (Hawaii) specimens. We report on a collection of this species from Iran, for the first time. Both the morphological features and ITS sequence confirm its identification as A. subrufescens. Its ITS sequence was of type C and even identical to that of specimens previously reported from Hawaii, China, and Thailand. This sequence differed from those of Europe or the Americas, where most current cultivars originate. The discovery of a specimen likely native to Iran extends the known distribution range of the ITS sequence of type C from East Asia to Iran. More collections from West Asia (and elsewhere, for example Africa) would help to better know the distribution area of the different types of ITS sequences and to increase the available germplasm resources of A. subrufescens.

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.
