Abstract
A combined molecular phylogenetic and morphological analysis revealed four species in the genus Tomentypnum. In addition to the commonly accepted widespread T. nitens and North American T. falcifolium, a strong genetic isolation is shown for two taxa. Tomentypnum involutum is elevated from variety to species status; it is widely distributed in permafrost areas in Siberia, the islands of the Arctic Ocean, high mountains in Scandinavia, and is known from the Rocky Mountains of Canada and from Greenland. Tomentypnum vittii is described as a new species for eastern Asia and Siberia, in China and Russia previously referred to T. falcifolium. Descriptions, illustrations, a key for identification, and a map for the Eurasian distributions are provided. Tomentypnum nitens is represented by four groups of haplotypes, which lack morphological distinction, and are therefore referred to one species. However, the distributions of the haplotype groups are revealing; some are more confined to mires rich in relic species composition, whereas others are more widely distributed and partly seem to occur in recently recolonized sites. Different distribution patterns in densely sampled Sweden suggest different glacial and postglacial histories.

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
