Culture experiments and DNA sequence data confirm the identity of<i>Lobaria</i>photomorphs
Bibliographic record
Abstract
Lichens consist of a fungal component that associates with either a green alga or cynobacterium, resulting in diverse morphologies. Resynthesis experiments of isolated myco- and photobionts, as well as internal transcribed spacer (ITS) rDNA phylogenies, suggest that the notoriously dissimilar photomorphs of Lobaria fendleri (Tuck. ex Mont.) Lindau and Lobaria amplissima (Scop.) Forss. both have a single mycobiont, which can simultaneously lichenize two unrelated photobionts, a eukaryote and a prokaryote. In the phylogenetic analyses, the genera Sticta and Durietzia appear monophyletic; whereas Lobaria and Pseudocyphellaria are both nonmonophyletic. Furthermore, the phylogenetic relationships of Durietzia, Lobarina, and Sticta relative to Lobaria and Pseudocyphellaria are in need of re-evaluation.Key words: internal transcribed spacer (ITS), photosymbiodeme, phylogeny, lichen-forming fungi, Lobaria amplissima, Lobaria fendleri, Pseudocyphellaria, Sticta.

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.
