Bibliographic record
Abstract
Abstract A new cyanolichen,Peltigera islandicasp. nov. in the sectionPeltigera(‘P. caninagroup’) is described from Iceland. This species is similar in general appearance toP. rufescensandP. membranacea, but may be recognized by its downturned lobe tips and narrow lobes, respectively. Most thalli are bright emerald green in colour when moist, although a dark khaki green colourmorph is also documented. Monophyly ofP. islandicas. lat. (i.e. includingP. sp. AsensuO’Brienet al., from Canada) is significantly supported based on ITS sequences and corroborated by molecular synapomorphy (absence of the ITS1 hypervariable region). Analysis of therbcLX locus indicates the cyanobiont ofP. islandica(Nostocsp.) comprises strains belonging to a pool of Icelandic genotypes, some of which are present in otherPeltigeraspecies, includingP.“neorufescens”, another taxon new to Iceland collected during this study. Association with photobionts that are shared by other local species suggestsP. islandicamay be well established in Iceland, but a review of herbarium collections as well as broader field surveys are needed to better characterize its geographical distribution.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
