Abstract
Trichomycetes, an ecological grouping of fungi and protists associated with the guts of aquatic arthropods, are distributed globally. The diversity of this unique species complex is, however, more completely documented in some parts of the USA and Europe than in Canada. Twenty species of trichomycetes were collected from insect hosts at six sites in Prince Edward Island, situated in the Gulf of St. Lawrence about 14 km off the east coast of New Brunswick. Five new species of Harpellales (Fungi, Kickxellomycotina), Caudomyces longicollis Strongman sp. nov. from Antocha sp. (Tipulidae), Legeriomyces minae Strongman sp. nov. from mayflies, and Smittium ditrichosporum Strongman sp. nov., Smittium insulare Strongman sp. nov., and Smittium tynense Strongman sp. nov. from chironomids are described. Smittium brevisporum L.G. Valle & Santam. and Smittium gracilis L.G. Valle & Santam., previously known only from Spain, are recorded for the first time in North America. A number of species of Harpellales and Amoebidiales (Phylum Mesomycetozoa) previously recorded from the region (P.E.I. and N.S.), and several that are common and widely distributed, were also recovered. Stachylina pedifer Lichtw. & M.C. Williams was collected from chironomids in a stream exposed to seawater during high tide. Trichomycete diversity is high on P.E.I., as it is in many regions where extensive surveys have been conducted, including islands such as Australia and New Zealand. More data from islands may help shed some light on distribution patterns for these obligate endobionts and provide some insights into mechanisms for dispersal.
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.
