Description: Pileus -40 mm, hemispherical becoming convex finally umbonate-expanded or campanulate; grey to fuliginous, especially over disc; glutinous, opaque, membranaceous, substriate. -Lamellae 8-12 (1-5) rather distant, adnate to emarginate-adnexed, ventricose, up to 5 mm wide, occasionally anastomosing; white turning pale grey, edges concolorous, entire, gelatinous thread absent - Stipe 25-50 x 2.5 -4 mm, cylindrical, equal; pale grey, whitish at base; glutinous, fistulose to hollow, veil remnants absent, single. - Context whitish, brittle. – Odour and taste not distinctive. -Chemical reactions on pileus: KOH - negative. - Spore print white. Spores 5.5-7 x 4-4.5 um, ovoid, smooth, hyaline, inamyloid. - Basidia 30-40 x 5-6 um, 4-spored, rarely with 2 sterigmata, with clamp connection at basal septum. - Cheilo- and pleurocystidia absent - Pileipellis an ixocutis of densely interwoven, 2 cylindrical hyphae (1-4 um diam.), membrane  strongly gelatinised, hyaline, with grey plasmatic pigment, septa usually lacking clamp connections.
ECOLOGY: Rare; saprobic on soil among litter in  mixed broadleaved-conifer forest (Weinmannia, Metrosideros, Dacrydium, Dicksonia). March.
Distribution: DISTRIBUTION: NZ (WL).
Notes: ETYMOLOGY: fumosus = sooty; griseus = grey.
The strongly gelatinised pileus and stipe clearly  indicate that this grey to sooty coloured species has its taxonomical position in Gliophorus. Its identification is easy because G. fumosogriseus is the only New Zealand Gliophorus with adnate-emarginate lamellae in combination with fuliginous colours on the basidiomes.
