First record of trichomycete fungi from Rouge National Urban Park and Greater Toronto Area
Bibliographic record
Abstract
Insect gut-dwelling fungi, also known as trichomycete fungi, are obligate symbionts that reside in the digestive tracts of freshwater insect larvae or nymphs. Trichomycete fungi have been extensively documented worldwide and hold significant ecological and evolutionary importance. However, their distribution in Rouge National Urban Park (RNUP) and Greater Toronto Area (GTA), Ontario, Canada, remains underexplored. To enhance our understanding of microbial fungal resources in Canada and to examine trichomycetes diversity in urban environments, a comprehensive study was conducted in RNUP and associated watersheds in GTA, including Highland Creek, Little Rouge Creek, and West Duffins Creek. A total of 28 collection sites were sampled, leading to the identification of various species new to the area, including Caudomyces sp., Ejectosporus trisporus, Genistelloides sp., Stachylina paucispora, Stachylina penetralis, Trichozygospora chironomidarum, Smittium caudatum, Smittium culicis, and Smittium simulii. Our findings significantly expand the known distribution of these symbiotic fungi in urban environments and underscore the importance of these habitats as reservoirs of microbial fungal diversity.
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.
