Asexual-sexual morph connection in the type species of Berkleasmium
Bibliographic record
Abstract
Berkleasmium is a polyphyletic genus comprising 37 dematiaceous hyphomycetous species. In this study, independent collections of the type species, B. concinnum , were made from Eastern North America. Nuclear internal transcribed spacer rDNA (ITS) and partial nuc 28S large subunit rDNA (LSU) sequences obtained from collections and subsequent cultures showed that Berkleasmium concinnum is the asexual morph of Neoacanthostigma septoconstrictum ( Tubeufiaceae , Tubeufiales ). Phylogenies inferred from Bayesian inference and maximum likelihood analyses of ITS-LSU sequence data confirmed this asexual-sexual morph connection and a re-examination of fungarium reference specimens also revealed the co-occurrence of N. septoconstrictum ascomata and B. concinnum sporodochia. Neoacanthostigma septoconstrictum is therefore synonymized under B. concinnum on the basis of priority. A specimen identified as N. septoconstrictum from Thailand is described as N. thailandicum sp. nov., based on morphological and genetic distinctiveness.

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.
