A new species of <i>Harposporium </i>parasitic on nematodes
Bibliographic record
Abstract
A new species, Harposporium thaumasium X. Li et K.Q. Zhang, was isolated from forest soil in Yunnan, China. This species produces small, curved conidia, singly or in groups, from globose or ellipsoid phialides. Unlike other known Harposporium, this species produced novel arthroconidia that did not disarticulate at septa but germinated to produce typical phialides and infective conidia. Solitary or catenulate chlamydospores were also produced within infected nematodes and in pure culture. Narrowly elliptical to D-shaped accessory conidia were produced, only on potato dextrose agar and dextrose yeast agar, from mono- or poly-phialidic conidiogenous cells resembling Hirsutella; thus, on these nutrient media, four different spore types were formed. Infection tests showed that curved conidia of the species were capable of killing bacteria-feeding nematodes (Panagrellus redivivus) when ingested, and the infection was initiated by lodging of the conidia in the gut region. Accessory conidia were not observed to be infective or adhesive.Key words: endoparasitic fungi, Harposporium thaumasium sp.nov., ingested conidia, nematode.

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.
