Transfer of two <i>Helicoma</i> species to <i>Troposporella</i> based on molecular and morphological data
Bibliographic record
Abstract
Previous molecular data demonstrated that, although Helicoma is polyphyletic, most species in the genus, including the type Helicoma muelleri, are in the Tubeufiaceae. Here, we use analysis of the small subunit and internal transcribed spacers (ITS) rDNA regions to show that two species, H. monilipes and H. olivaceum, are phylogenetically distant from the type, branching outside of the Tubeufiaceae near Troposporella fumosa in a basal clade of the Dothideomycetes. The phylogeny does not support the recent transfer of T. fumosa to Helicoma. Instead, based on the molecular evidence as well as the examination of cultures and type specimens, Troposporella is reinstated at the generic level, and Helicoma monilipes and Helicoma olivaceum are transferred to Troposporella. All three Troposporella species share the production of helicoid conidia borne on sporodochial conidiomata from blastic conidiogenous cells. A key to accepted species is provided.

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.
