Contribution to rust flora in China I, tremendous diversity from natural reserves and parks
Bibliographic record
Abstract
Rust fungi taxonomically belonging to Pucciniales ( Basidiomycota ) are important phytopathogens that cause many significant diseases to agricultural crops and forest trees. Hitherto, ca. 8000 and 1200 species have been reported from worldwide and China, respectively. To investigate and document the diversity of rust fungi in China, we have sampled from 86 natural reserves and national parks in the past several years, and 6627 specimens have been collected. Our identification using both morphological and molecular data assigned 1654 collections to 337 species in 43 genera of 15 families, as cataloged in this paper. Among them, 34 new species are formally described based on their morphological distinctions and phylogenetic relationships. In addition, three new families Endoraeciaceae , Neophysopellaceae and Uromycladiaceae are proposed based on their morphological distinctions, phylogenetic independences and divergent times. Considering the traditionally morphologically defined families in Pucciniales have been increasing revealed to be discordant with phylogenetic groupings, taxonomic revisions are needed in future study to establish a natural classification system in Pucciniales. We also discussed the importance of morphologies in spermogonia and aecia for the delimitation of Puccinia and related genera. This study presents a significant contribution to the knowledge of rust flora in China. Taxonomic novelties: new families: Endoraeciaceae P. Zhao & L. Cai; Neophysopellaceae P. Zhao & L.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
