Abstract
Polar, high altitude montane and cold desert environments harbour only sparse plant life and often remain frozen for extended periods. Because of their remoteness, often combined with restricted access, such regions are rarely visited and the fungal biodiversity of the soils is scarcely studied. Despite this, when such studies are undertaken, psychrophilic Penicillium species are often reported and the isolates exhibit a high spectrum of biologically species concepts and provide information to characterize variation within species or populations. During large scale fungal isolation surveys exploring new psychrophilic fungi from high altitude alpine and arctic tundra soils, several undescribed Penicillium species were discovered. A polyphasic taxonomic approach was adopted to formally describe ten new species using multigene phylogenetic analyses and phenotypic characterizations including secondary metabolite production, colony characters, and microscopic analysis of morphological structures. Using untargeted metabolomics and molecular networking tools, an emphasis was made to characterize, compare and discuss in depth, the chemical diversity associated with these new Penicillium species.

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 it
