Remarks (public):Cortinarius balteatoindicus is a member of the sect. Phlegmacioides based on morphological and molecular (nrDNA ITS and LSU regions) evidences where it belongs to the /balteatocumatilis clade. It forms a well-supported (BS = 99%) lineage with three sequences known from the Americas: USA, Tennessee (GenBank: MF773626), USA, Minnesota (GenBank: KY964808) and Mexico (GenBank: EU569251).The closest sequence is the one from Minnesota, they differs by 5 nucleotide and indel positions, but only in the ITS1 region. Further studies needed to unveil whether this sequence belong to C. balteatoindicus with such a disjunct distribution. The other North American sequence from Tennessee differs by 8 nucleotide and indel positions, so it might well represent an own species. The phylogenetically more distant European species of this clade have more robust basidiomata too, e.g. C. balteatocumatilis, C. balteatobulbosus, C. pseudonebularis, and the recently described C. hemicaeruleus (Brotzu et al. 2019) and have usually slightly larger spores. The special ecology and the unique ITS sequence is, however, the best delimiting characters for the time being.

Description:Pileus up to 75 mm in diam., plano-convex to applanate, slightly glutinous when young, reddish golden to greyish orange (6B7–6B5); margin smooth or slightly innately fibrillose, incurved. Lamellae emarginate, moderately crowded, up to 6 mm broad, greyish when young, later greyish orange (6B4–6B6), lamellulae present, of various lengths. Stipe 65 × 17 mm, cylindrical, with slightly clavate base, up to 25 mm broad, greyish orange to brownish orange (6B5–6B6). Context dull lilac (15C3) to purplish in pileus and in stipe base. Odour distinct, earth-like. Taste indistinct. Spore print light brown (6D8). Basidiospores (9.4–)9.7–10.3(–10.7) × (5.4–)5.6–5.9(–6.1) μm, Av = 10.07 × 5.7 μm, Q = (1.65–)1.73–1.80(–1.85), Qav = 1.77, n = 50, amygdaloid, verrucose. Basidia 4-spored, 26–32 × 6–8 μm, clavate. Pileipellis more or less simplex (mono-layered); strongly coloured in KOH. Epicutis at surface of narrow (2–4 μm wide), loosely erect-entangled, gelatinous, distinctly brownish yellow hyphae (many more or less collapsed); below wider (4–8 μm wide), parallel hyphae, with yellow thick walls or distinctly zebra-striped, encrusted pigment; the basal part of epicutis of more or less cemented hyphae up to approx. 15 μm wide, with distinctly thickened, yellow walls, some filled with dark brown granulate to oleiferous pigment (most pigment in the basal, cemented part). Habitat and distribution — Solitary, occurring among leaf litter in temperate forests dominated mainly by Quercus leucotrichophora, and Pinus roxburghii.
