Two new genera and six other novelties in <i>Heterochaete</i> sensu lato (Auriculariales, Basidiomycota)
Bibliographic record
Abstract
The genus Heterochaete (Auriculariales, Basidiomycota) is traditionally defined as comprising resupinate fungal species with sterile spines (hyphal pegs) that are distributed on hymenial surface. Recent DNA-based studies have indicated that Heterochaete is polyphyletic, although the correct taxonomic positions of many species under this genus remains unresolved. In this study, we revised the taxonomic assignments of some representatives of Heterochaete s.l., with special emphasis on neotropical taxa. Based on our results, two new genera, three new species, and three new combinations are proposed. Adustochaete is a new genus comprising two newly described species collected from dry hardwood twigs in the Neotropics; these two species are Adustochaete rava (the genus type) from Brazil and Adustochaete interrupta from Mexico. To date, the second genus, Proterochaete, comprises a single species, Proterochaete adusta comb. nov., which is widely distributed in the temperate Northern hemisphere. In addition, one new species, Tremellochaete cerradensis sp. nov., is described and one new combination, Tremellochaete ciliata comb. nov., is proposed in Tremellochaete, both recorded in Brazil. A neotype is selected for Heterochaetella ochracea, and this species was moved to Eichleriella based on morphological evidence and DNA analyses.

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.
