Austroboletus olivaceoglutinosus is a species of bolete fungus found in Sikkim in northeast India.

[1] The species name is derived from the latin words oliva "olive" and glūtĕn "glue",[2] and refers to the mushroom's cap.

It is solid in young specimens, with the inner pith softening and leaving a hollow stem in older mushrooms.

The flesh does not change colour when potassium hydroxide is applied to it, but the cap surface turns salmon-pink.

The mushrooms appear in August and September in subalpine coniferous forests at an altitude of 2,800 metres (9,200 ft), under such trees as Sikkim spruce (Picea spinulosa), Bhutan fir (Abies densa), Sikkim larch (Larix griffithiana) and Himalayan hemlock (Tsuga dumosa).
