Redefining <i>Microascus, Scopulariopsis</i> and allied genera
Bibliographic record
Abstract
The genera Microascus and Scopulariopsis comprise species commonly isolated from soil, decaying plant material and indoor environments. A few species are also recognised as opportunistic pathogens of insects and animals, including humans. In the past, the taxonomy of these fungi has been based on morphology only. With the aim to clarify the taxonomy and phylogeny of these fungi, we studied a large set of clinical and environmental isolates, including the available ex-type strains of numerous species, by means of morphological, physiological and molecular analyses. Species delineation was assessed under the Genealogical Phylogenetic Species Recognition (GCPSR) criterion using DNA sequence data of four loci (ITS region, and fragments of rDNA LSU, translation elongation factor 1-α and β-tubulin). The genera Microascus and Scopulariopsis were found to be separated in two distinct lineages. The genus Pithoascus is reinstated and the new genus Pseudoscopulariopsis is erected, typified by P. schumacheri. Seven new species of Microascus and one of Scopulariopsis are described, namely M. alveolaris, M. brunneosporus, M. campaniformis, M. expansus, M. intricatus, M. restrictus, M. verrucosus and Scopulariopsis cordiae. Microascus trigonosporus var. macrosporus is accepted as a species distinct from M. trigonosporus. Nine new combinations are introduced. Microascus cinereus, M. longirostris, P. schumacheri and S. flava are neotypified. A table summarising the morphological features of the species treated and identification keys for each genus are provided.

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.
