E87A87B3FFF7F021FF6E2B3C5132F814.taxon	description	Description: Basidiomata medium-sized, firm, fleshy, with dark greenish tone. Pileus 41 – 57 (– 98) mm, hemispherical or obtusely conical with strongly involute margin at first, then expanded to almost flat with prominent obtuse umbo, first rather dark yellow (# 917625) or olivaceous brown (# 676700) with dark greyish (# 1 b 1 b 00) to blackish brown (# 424200) centre, then paler especially in marginal zone towards light greyish (# 786 e 4 c) or olivaceous brown (# 676700), mostly with olivaceous (# 9 b 8957) or dark greenish (# 4 e 4 e 00) tinge, centre always much darker, very strongly glutinous. Lamellae adnate to subdecurrent, thick and waxy, white (# ffffff), partly gradually turning light yellowish green (# cccc 00) to drying cream (# ffeb 07) when bruised. Stipe 38 – 79 × 10 – 23 mm, cylindro-clavate to ventricose, often flexuous or bent and tapering-rooting towards the base, connected with margin of cap by a glutinous hyaline veil when young, then veil burst and disappear with maturity, with an unconspicuous annular zone at the apex, pale yellowish white (# ffffd 6), smooth or with white (# ffffff) floccules above the annular zone, covered by successive bands of thickly glutinous, dark brown (# 856731) or greyish brown (# 433419) flocci below, drying greybrown (# 686042). Context thick, pure white (# ffffff), in stem also white or slightly yellowish at base. Smell indistinct. Taste not recorded. Spore deposit white. Basidiopores ellipsoid to broadly ellipsoid or somewhat ovoid, measuring (8.5 –) 9.0 – 10.5 (– 11.0) × (4.5 –) 4.8 – 5.8 (– 6.0) μm; Q = 1.58 – 2; Qm = 1.79 ± 0.11, with an oblique hilar appendage 1 – 2 μm long; inamyloid, hyaline and smooth or microguttulate in water, appearing monoguttulate in KOH. Basidia 2 - spored or 4 - spored, clavate, 35.0 – 46.5 × 8.0 – 10.5 μm, some with oily refractive content in KOH; sterigmata 3.5 – 5.5 μm long. Cystidioid elements absent. Hymenophoral trama divergent, comprised of cylindrical, interwoven, branched hyphae 3 – 13 μm wide. Pileipellis an ixotrichoderm composed of thick-walled, hyaline or brown-pigmented interwoven hyphae 2.5 – 4 μm wide, hyaline or with olive green intracellular pigment, sparsely branching and embedded in a gelatinous matrix; incrustations or extracellular pigment not seen. Subpellis composed of more or less parallel hyphae up to 9 μm wide. Stipitipellis an ixotrichoderm, made up of branched hyphae 3 – 5 μm wide, with yellowish brown intracellular pigment; terminal elements rounded to attenuated, not enlarged. Stipititrama composed of densely packed, more or less parallelly arranged, subhyaline hyphae up to 9 μm wide. Floccules at the apex composed of compact fascicles of branched hyphae with cylindrical or slender clavate terminal elements 37 – 74 × 5 – 9 μm. Clamp connections present in all tissues.	en	Zhang, Yu-Xin, Mao, Ning, Fan, Li (2023): Hygrophorus viridiflavidus sp. nov. (Hygrophoraceae, Agaricales), from North China.
