Bibliographic record
Abstract
Calocybe violacea T. Bau & L.S. Mu, sp. nov. (Figure 3a–b, Figure 4a–d). MycoBank: 846890 Diagnosis:—Differs from related species by its convex to applanate, purple to bluish-purple pileus, white lamellae, purple-black, bluish-purple to white stipe, and relatively larger basidiospores, pileipellis a cutis, hyphae light purple-brown, stipitipellis composed of hyphae light brown, light purple-brown and light purple. Etymology:—Refers to the blue-purple color on the cap and stipe of basidiomata. Holotype:— CHINA. Yunnan Province: Chuxiong Yi Autonomous Prefecture, Chuxiong, Lucheng Town, Haizi Dam, in a forest dominated by Quercus spp., elevation 1836 m, 101°57’E, 24°97’N, 30 November 2021, leg. Jianneng Zhao (HMJAU65324). Description:— Basidiomata small-sized. Pileus 2.5–3.5 cm diam., hemispherical, margin involute when young, becoming convex to applanate at maturity, surface dry, purple-black (18D5) to dark purple (17E8) at center, becoming purple (17C6) to bluish-purple (19A4) towards the margin; context white (19A1). Lamellae sinuate to adnate, crowded, L=50–60, I=1–3, white (19A1), edge entire. Stipe 4.5–7.5 × 0.5–1 cm, central, cylindrical, purple-black (18E5), purple (18C6), bluish-purple (19B6), blue (21A7) to white (19A1), with white pubescence at the base, fibrous. Odor faint. Spore deposit white. Basidiospores (5.7) 6.4–6.7 (7.6) × (2.6) 3.0–3.2 (3.4) μm, 6.5×3.1 µm on average, Q=1.86–2.46, Q m =2.12 ± 0.12, oblong, colorless, hyaline, smooth, thin-walled, with oil droplets, cyanophilous, inamyloid. Basidia 15–24 × 5–7 μm, clavate, with oil droplet, with 4 (2) sterigmata, hyaline, smooth, thin-walled, with siderophilous granules. Hymenophoral trama regular, thin-walled, colorless, smooth, 4–11 μm wide. Cystidia absent. Pileipellis a cutis, hyphae 3–9 μm wide, light purple-brown after. Stipitipellis composed of thin-walled, 2–4 µm wide hyphae often light brown, light purple-brown, and light purple. Clamp connections present. Habit, habitat, and distribution: Gregarious, on soil in broad-leaved forests dominated by Quercus spp. Additional specimen examined: Chuxiong Yi Autonomous Prefecture, Chuxiong, Lucheng Town, Haizi Dam, in a forest dominated by Quercus spp., elevation 1836 m, 101°57’E, 24°97’N, 26 November 2021, Jianneng Zhao (HMJAU65325, paratype!).

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.
