Abstract

fetched live from OpenAlex

Cytospora piceae X. L. Fan, in Pan, Zhu, Tian, Alvarez & Fan, Phytotaxa 383 (2): 188 (2018) Fig. 3 Description. Sexual morph: not observed. Asexual morph: Conidiomata pycnidial, immersed in bark, erumpent, ostiolated, with multiple irregularly arranged circular or ovoid locules, 1,050 –1,400 μm in diam. Conceptacle absent, ostiole conspicuous, circular, dark gray, at the same level as the disc. Conidiophores semimacronematous, hyaline, filamentous, mainly unbranched or branched at base, elongated, smooth, thin-walled, (16.0 –) 17.7–22.2 (– 23.5) μm. Conidiogenous cells enteroblastic, polyphialidic. Conidia abundant, single, hyaline, aseptate, curved, allantoid, thin-walled (5.0 –) 5.4–6.1 (– 6.5) × (1.0 –) 1.2–1.5 μm. Culture characteristics. Colonies on MEA initially white, becoming beige with dense aerial mycelium, slow-growing (17 mm in diameter) after 7 days of incubation. Hyphae hyaline, smooth, branched, and septate. Material examined. Canada • Ontario, Lincoln, 43°06'38.2"N, 79°19'17.5"W, branches of Picea glauca (Moench) Voss, pycnidia (conidiomata) formed on cankered branches and twigs, April 2020, E. Ilyukhin (BILAS 51883, DAOM 985023, DAOMC 256987). Notes. Morphologically, two isolates of C. piceae are very similar, but EI-19 (A) has slightly longer conidiophores and conidia than CFCC 52841. Originally, C. piceae was described as a pathogen associated with the canker disease of Picea crassifolia in China (Pan et al. 2018). But the species was isolated from different hosts (including non-conifers) in other parts of Canada based on ITS sequence data (ON 352565, PQ 671332, PQ 671333, PQ 666762) available in GenBank.

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.

Not 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.
