Abstract
The genus Aitchisoniella with a single species A. himalayensis (Marchantiopsida, Cleveaceae), previously considered endemic to the north-west Himalayas of India, is reported for the first time from Sichuan Province, China. The genus is distinctive amongst complex thalloid liverworts in lacking stalked carpocephala but having archegonia and sporophytes borne on the ventral side of a short receptacle arising in a terminal thallus bifurcation. The receptacle tissue is continuous with that of the main thallus, with dorsal air chambers and air pores, and a ventral groove containing pegged rhizoids. Both molecular data and morphological characters, particularly spore ornamentation, suggest that its previous placement in Exormothecaceae is incorrect and it is now transferred to Cleveaceae, wherein it becomes the fifth genus. Revised descriptions of the families Cleveaceae and Corsiniaceae (including Exormothecaceae) are provided.

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
