The cap of adult mushrooms is 2-6 cm in diameter, in young mushrooms it is hemispherical to blunt, then convex and flattened, sometimes slightly depressed, with a tubercle in the center, not hygrophic, covered with a layer of mucus, especially in wet weather. The color of the hat is gray-brown or olive-brown, in the center it is darker, with a little lighter color.

The plates are rare, waxy, adhered to the leg or slightly descending on it, sometimes branching and interwoven, white or cream color.

The pulp is strong, white, often yellow under the skin in the center of the hat, and fibrous in the leg. Odor and taste are not expressed.

Leg 4-8.5 (10) cm long and 0.4-1.0 (1.2) cm thick, central, cylindrical or spindle-shaped, with mucous common and fibrous private bedspreads, then expanding, forming a mucous, soon disappearing ring , above the ring it is dry, white, often with a subtle whitish pubescence, below is the mucous membrane, first olive-brown, then with brownish to dark brown belts on a light background, especially bright when dried.
