Epitypification of Agaricus vittadinii (Basidiomycota, Amanitaceae)
Bibliographic record
Abstract
Agaricus vittadinii Moretti (1826a: 66) is a striking species traditionally ascribed to the genus Amanita Pers. (1797: 65) (Bas 1969; Traverso 1998; Neville & Poumarat 2004). Amanita is one of the most widespread, species-rich ectomycorrhizal genera (Yang 1997; Yang et al. 1999; Neville & Poumarat 2004; Tulloss 2000; Kirk et al. 2008; Tulloss & Yang 2015), characterized by usually agaricoid basidiomata (including sequestrate forms) with a pallid spore print, a hemiangiocarpic schizohymenial development, presence of both universal and partial veils, and usually white and free lamellae (Bas 1969; Neville & Poumarat 2004; Justo et al. 2010). Microscopically, diagnostic characters are amyloid or inamyloid spores, bilateral hymenophoral trama and longitudinally acrophysalidic stipe tissue, which consists of clavate, usually terminal elements, longitudinally oriented on a diffuse system of narrow, branching hyphae (Corner & Bas 1962; Bas 1969; Jenkins 1986; Yang 1997, 2005; Traverso 1998; Neville & Poumarat 2004).

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.
