Identity of <i>Guignardia</i> sp. inhabiting ericaceous plants
Bibliographic record
Abstract
An ascomycete belonging to the genus Guignardia with a Phyllosticta anamorph was frequently isolated from living leaves of several ericaceous plants. Ecological study on assemblages of endophytes suggested that this fungus is a dominant endophytic fungus of ericaceous plants. The Phyllosticta anamorph was morphologically similar to Phyllosticta capitalensis P. Henn., which can be a pathogen of orchids. An authentic culture of P. capitalensis IFO 32914 (= CBS 226.77) produced an ascigerous stage on potato dextrose agar, the morphology of which was identical to the Guignardia sp. from ericaceous plants. Sequence data of the internal transcribed spacer regions of ribosomal DNA (ITS1 and ITS2, including 5.8S rDNA) supported the identity of the present fungus and P. capitalensis. Consequently, we describe this endophytic ascomycete found from ericaceous plants as Guignardia endophyllicola sp.nov., which has P. capitalensis as an anamorph. Previously known as a pathogen of orchids, the fungus was revealed to exist widely as an endophyte within ericaceous plants.Key words: endophytic fungus, Ericaceae, Guignardia endophyllicola, pathogenic fungus, Phyllosticta capitalensis, Orchidaceae.

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.
