New records and range extensions in the North American lignicolous lichen flora
Bibliographic record
Abstract
Based on recent intensive studies of wood-dwelling lichens especially in western North America, we report a series of new records and range extensions.Six species are reported as new to North America: Arthonia ligniariella, Elixia flexella, Gyalideopsis helvetica, Lecidea scabridula, Lecidea symmictella and Xyloschistes platytropa.Chaenothecopsis nigra is again confirmed for North America.Buellia arborea, B. chloroleuca, Catillaria erysiboides, and Lignoscripta atroalba are new to Canada and Lecidea pullata and Xylographa trunciseda are new to eastern North America.We also provide range extensions for all four species of Pycnora known from North America.In all we include new records from Alaska, Arizona, British Columbia, Colorado, Idaho, Manitoba, Montana, New Brunswick, Newfoundland, North Dakota, Northwest Territories, Nunavut, Ontario, Québec, Washington and the Yukon.
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.
