Reports of<i>Cladonia magyarica</i>and<i>C. humilis</i>in Manitoba
Bibliographic record
Abstract
The genus Cladonia is widely distributed around the world. Since the section Cladonia contains species complexes that are difficult to distinguish, the distributions of species within these complexes are even less well-known than others. The cup-forming species, Cladonia magyarica, is morphologically similar to C. pyxidata and C. pocillum; and C. humilis is morphologically similar to C. conista and C. chlorophaea. Both species, C. magyarica and C. humilis, have not been previously reported for Manitoba, but their distribution ranges fall very close to the province, and they grow in habitats that are present in southern Manitoba. The goal of this paper was to report the presence of C. magyarica and C. humilis in Manitoba representing range extensions for both species, and to show morphological differences among them and their close allies present in the same geographic locations. The morphological differences between C. magyarica and C. pyxidata include squamules inside the cup and a significantly taller podetium and wider cup diameter in C. magyarica than C. pyxidata. Cladonia magyarica also differs from C. pyxidata in possessing atranorin in addition to fumarprotocetraric acid, in every specimen we collected. Atranorin and fumarprotocetraric acid were also shown to be present in C. humilis, but C. humilis has soredia covering the podetium, which is not present in the aforementioned taxa.

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.
