A hidden basidiolichen rediscovered:<i>Omphalina oreades</i>is a separate species in the genus<i>Lichenomphalia</i>(Basidiomycota:<i>Agaricales</i>:<i>Hygrophoraceae</i>)
Bibliographic record
Abstract
Abstract Molecular studies have shown the type collection ofOmphalina oreadesto be conspecific with a small brown basidiolichen from the Appalachian range in Newfoundland, both with 4-spored basidia. Two sequences deposited in GenBank, originally identified asO. grisella, fell in the same clade. Sequences of the type collection ofOmphalia grisella, with 2-spored basidia, formed a sister clade together with two GenBank deposits, one identified asO. grisellaand the other asOmphalina velutina.Omphalina oreadesis recombined here asLichenomphalia oreadescomb. nov., and the species redescribed and illustrated. Sequences of the internal transcribed spacer regions of nuclear ribosomal DNA (ITS rDNA) from the algae associated with two collections ofL. oreadesfell within a highly supported clade with members of an undetermined species ofCoccomyxa. The most abundant algal ribosomal large subunit sequence from granules at the base of a different collection matched GenBank sequences identified asChloroidium ellipsoideum, which is probably either a free-living algal species or a partner to a species ofTrapeliopsis.The second most abundant sequence matchedCoccomyxa subellipsoideaand is the most likely photobiont ofL. oreades. Further studies are required to elucidate the relationship ofL. velutinato these taxa.

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.
