Myochromella unveiled: exploring its global distribution through a public database of amplicons
Bibliographic record
Abstract
Myochromella mammosa, a novel species from southwestern China, is distinguished by its small, solitary or gregarious basidiomata. The pileus is clock-shaped, with distinct central mastoids, edge stripes, and a darker center that flattens upon maturation. The stipe is white, firm when young, and becomes hollow and slightly thickened at the base with age. We conducted a comprehensive analysis of publicly available ITS sequences from NCBI-GenBank and fungal amplicon sequencing data from NCBI-SRA to explore the global distribution and enumeration of recorded species of Myochromella. At a 98% sequence similarity threshold, eleven species were identified, including eight without formal designations. Myochromella's diversity is primarily Northern Hemisphere-centric and tends toward endemic distribution. Leveraging amplicon sequencing data sets enables precise species diversity assessments, enhancing field collection efficiency and providing novel insights into macrofungal species diversity.

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.
