Abstract
Blastobotrys plurivorus M. Groenew., M.T. Sm, Hern.- Restr. & Decock, sp. nov. MB 860915. Fig. 7. Etymology: plurivorus (Lat., noun); named as strains from this species were isolated from various substrates. Typus: The Netherlands, isolated from mouse-dung, 1977, unknown collector (holotype designated here and preserved in a metabolically inactive state, CBS 137.78; ex-type strain CBS 137.78). Description: Budding cells globose, 1.5–2.5 µm diam, or ovoid, 2–4 × 2.5–5 µm. Hyphae hyaline, septate, without denticles, 1.5–2.5 µm wide. Pseudohyphae hyaline without denticles. Secondary conidia produced by primary conidia at the apex, globose 1–1.5 µm diam. Sexual reproduction has not been observed in the single strains nor in the pairwise mixtures. Culture characteristics: After 2 wk at 24 °C on GPYA the culture is snow-white, dry, dull, tough and corrugated. Physiological characteristics: Fermentation of D-glucose and D-galactose is weak (delayed) and is absent for sucrose, maltose, lactose, raffinose and trehalose. Carbon compounds assimilated are D-glucose, D-galactose, lactose © Westerdijk Fungal Biodiversity Institute 320 (weak), trehalose, maltose, cellobiose, L-sorbose, D-xylose, L-arabinose, D-ribose, glycerol, erythritol, D-mannitol, D-sorbitol, glucosamine, N -acetyl-D-glucosamine, potassium-2-keto-D-gluconate and D-glucuronate, while growth is absent on sucrose, raffinose, melibiose, melezitose, methyl-α-D-glucoside, L-rhamnose, inositol, lactic acid and D-gluconate. Growth is positive on ethylamine, L-lysine, cadaverine and D-glucosamine HCl and negative on nitrate as sole nitrogen compounds. Growth occurred at 6 °C and 30 °C and is absent at 37 °C. Growth in the presence of 0.01 % cycloheximide is positive. Additional materials examined: France, Occitanie, from a basidiome of Donkioporia expansa (Polyporales) growing on Quercus wood, Jan. 2014, C. Decock, strain CBS 17992 = MUCL 55272; Mediterranean area, from a basidiome of Fomitiporia pseudopunctata (Hymenochaetaceae), Apr. 2015, C. Decock, strain CBS 18001 = MUCL 46524. Distribution and substrates: This species is known from France (basidiome), and The Netherlands (mouse dung). According to the GlobalFungi database, samples with identical ITS sequences were obtained from samples originating from St. Helena (Peak Dale), Iran, Europe (Austria, Belgium, Czech Republic, Estonia, France, Germany, Hungary, Netherlands, Sweden, and UK), and North America (Canada), growing on soil, deadwood, shoot, and air samples from forest, woodland, cropland and anthropogenic biomes. Notes: The three B. plurivorus strains, CBS 137.78, CBS 18001 and CBS 17992 are identical in both the ITS and LSU regions. The ex-type strain (CBS 137.78) differs from the ex-type strain (CBS 140.71) of B. farinosus with 75 nt (29 gaps) and 28 nt (five gaps) in the ITS (533 nt) and LSU (842 nt) regions respectively. Blastobotrys plurivorus and B. farinosus showed no significant physiological differences (Table 3).

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.
