The genus Caeruleum (Lichinomycetes, incertae sedis): A new species from South Africa and a preliminary revision of the genus in North America
Bibliographic record
Abstract
Abstract We describe the new species Caeruleum terricola from Grootbos Private Nature Reserve in the Overstrand Municipality of Western Cape Province, South Africa. The new species occurs on consolidated soil and is characterized by its lack of an epigeic thallus, innate apothecia that are often blue-gray to green pruinose and polysporous asci. Nuclear and mitochondrial ribosomal DNA data place the new species within the genus Caeruleum in the Lichinomycetes . We discuss the taxonomic status of previously described species of Caeruleum and their relationship to our new species with particular emphasis on the status of the genus in North America and make the new combination Caeruleum aeruginosum . We also discuss other polysporous species of lichenized fungi reported from South Africa, an unexplained insertion in the ITS1 section of the genome of C. terricola, and how the addition of this and other species affects the systematic relationships within Lichinomycetes, specifically the circumscription of the Thelocarpaceae and its constituent genera .

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.
