A new conifer-inhabiting species of <i>Ceratocystis</i> from Norway
Bibliographic record
Abstract
A new species, Ceratocystis norvegica J. Reid & Hausner sp. nov., is described from Norway. Based on morphological criteria and analyses of rDNA internal transcribed spacer and small subunit rDNA sequences, strains collected from galleries of the bark beetle Ips typographus on Picea abies (L.) H. Karst, were shown to be distinct both from members of the Ceratocystis coerulescens complex and from other species described previously from conifers. Ceratocystis norvegica has the following defining characteristics: convergent ostiolar hyphae; a sharply defined temperature optimum at 20 °C; an apparent lack of a conidial state; and ascospores that on germination produce either self-fertile or self-sterile strains.
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.
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.
