<i>Ophiobolus hydei</i> sp. nov. (Phaeosphaeriaceae, Ascomycota) from <i>Cirsium</i> and <i>Phlomoides</i> in Uzbekistan
Bibliographic record
Abstract
We introduce a new fungal species, Ophiobolus hydei, from dead stems of Cirsium alatum (Compositae) and Phlomoides brachystegia (Lamiaceae), based on morphological and phylogenetic evidence. The species was collected from the Mountains of Western Tien Shan and southwestern Hissar in Uzbekistan. Ophiobolus hydei is characterized by globose to subglobose ascomata with short to long papilla, cylindrical to subcylindric-clavate asci, broad pseudoparaphyses, and scolecosporous, yellowish-brown to brown, filiform, multiseptate ascospores that can split into several part-spores at the septa. Multigene phylogenetic analyses using a combined gene analysis of ITS, LSU, SSU, and TEF1-α indicated that the new species has a close affinity to Ophiobolus ponticus, but differs from that species in the micromorphological characteristics of the ascomata, asci, and ascospores, as well as biogeographic distribution. A distribution map, morphological descriptions, and illustrations with colour photographs of the novel species are 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; both teacher heads agree on what is shown here.
