Bibliographic record
Abstract
Xylomelasma shoalensis A. N. Mill., Y. Marín & Stchigel, Sydowia 68: 224. 2016. Specimen examined. USA – Illinois • Montgomery County, Shoal Creek Conservation Area; 39.1871, - 89.5963; on 6 cm. diam. decorticated branch on the ground; 4 Apr 2004; A. N. Miller ANM 1 (holotype ILLS 76895!). Notes. The only available LSU sequence (KX 290919, Hernández-Restrepo et al. 2016) of X. shoalensis indicates that the species is a member of Ceratostomella (Fig. 1). Based on the sequence similarity with X. sordida (99.2 %), they are likely conspecific. However, according to its diagnosis, this species does not match the generic delimitation of Ceratostomella. Xylomelasma shoalensis was described with immersed, globose to subglobose and smaller (175–265 μm diam) ascomata featuring a rostrate, slender, non-sulcate neck and hyaline to yellowish-brown, oblong to suballantoid, septate ascospores in unitunicate asci. Its LSU sequence was not obtained from a mycelium of an axenic culture but directly from ascomata on the host. It is evident that morphology belongs to a different genus and species. We examined the holotype, but no traces of a Ceratostomella - like fungus could be found. Therefore, due to this ambiguity, X. shoalensis is excluded from Ceratostomella.
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.
