New species of <i>Spartiella</i> and <i>Legeriosimilis</i> from mayflies and other arthropod-associated trichomycetes from Nova Scotia, Canada
Bibliographic record
Abstract
The digestive tracts of non-predaceous, aquatic insects and other arthropods living in moist habitats harbour a group of fungal and protistan microorganisms known as trichomycetes or “gut fungi”. A former class of Zygomycota, “trichomycetes” now refers to an ecological group of gut microbes. This report adds to the growing inventory of gut fungi that have been described from Atlantic Canada, with two new fungal trichomycetes, Legeriosimilis hiemalis sp. nov. Strongman and M.M. White and Spartiella aurensis sp. nov. Strongman and M.M. White, both from Ephemeroptera (mayfly) nymphs. Legeriosimilis hiemalis is now the fourth of seven known species of the genus to be recorded only from Canadian sites. Spartiella aurensis displays an unusual feature, with thalli apparently able to grow from the hindgut back into the midgut of its host, a growth pattern not typically observed in other gut fungi. The potential significance of this development is discussed. Despite the focus on immature freshwater insects and their habitats, we also record a species of Orchesellaria from Collembola (springtails) and Astreptonema corophii from the amphipod crustacean Corophium volutator.
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.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
