Molecular phylogeny of four selected species of the strictly anamorphic genus <i>Thysanophora</i> using nuclear ribosomal DNA sequences
Bibliographic record
Abstract
To estimate the phylogenetic position of the strictly anamorphic genus Thysanophora among the class Ascomycetes sensu Kirk et al. and to examine the phylogenetic relationships among T. penicillioides and other Thysanophora species, 18S and 28S rDNA (D1 and D2 regions) sequences of 22 strains of four known and two unidentified Thysanophora species were determined and phylogenetically analyzed. The 18S rDNA analysis suggested that all Thysanophora species examined were members of Eurotiomycetidae, Eurotiales, Trichocomaceae. The 28S rDNA analysis indicated that these species were clustered together with Chromocleista, Eupenicillium, Geosmithia, and Penicillium assignable to three subgenera – Aspergilloides, Furcatum, and Penicillium. In the Eupenicillium lineage, a monophyly of T. penicillioides, T. longispora, T. taxi, T. canadensis, and T. cf. canadensis was supported by comparatively high bootstrap values. However, the ex-type strain and two strains of T. longispora isolated in Japan were of different phylogenetic positions. Thysanophora sp. was positioned at the base of the Thysanophora clade, although it was not supported by significant bootstrap values. From the results of this study, we consider that two anamorphic genera, Penicillium and Thysanophora, are clearly distinct in morphology but that they are not phylogenetically separable.

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.
