Bibliographic record
Abstract
Trichomycetes are endobionts that include both fungal and protistan species living in the guts of aquatic insects. Although widely distributed around the world, the biodiversity of these fungi in Canada is virtually unknown. We report the occurrence of 13 species of trichomycetes associated with stonefly nymphs in the families Capniidae, Leuctridae, Nemouridae, and Taeniopterygidae from collections spanning 8 years. This paper extends the geographical range for a number of known fungal species. We describe four new species of Harpellales, Lancisporomyces anguilliformis, Lancisporomyces falcatus, Lancisporomyces nemouridarum, and Orphella dalhousiensis, including both asexual and sexual features for each, as well as two new species of Paramoebidium (Amoebidiales), Paramoebidium cassidula and Paramoebidium stipula. The observations on zygospore morphology in Lancisporomyces and ontogeny of sexual spores in Orphella broaden our perspective on sexual reproduction in the Harpellales. Also highlighted are data on temporal aspects of species occurrence, asexual and sexual sporulation for some species that show host specificity as well as synchrony in maturation of the endobionts with their stonefly hosts.
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.
