Collection points:

Green moss is found in deciduous, coniferous forests and shrubs, usually in well-lit places (along the sides of paths, ditches, on the edges), sometimes it grows on rotten wood, anthills. It settles more often singly, sometimes in groups.


The cap is up to 15 cm in diameter, convex, fleshy, velvety, dry, sometimes cracked, olive-brown or yellowish-olive. Tubular layer adherent or slightly descending to the pedicle. The color is bright yellow, later greenish-yellow with large angular irregular pores, when pressed, they turn bluish-green. The pulp is friable, whitish or light yellow, slightly blue at the cut. Smells like dried fruit.

The leg is up to 12 cm, up to 2 cm thick, thickened at the top, narrowed downwards, often curved, solid. The color is yellowish-brown or red-brownish.


Green flywheel is similar to the yellow-brown flywheel and the Polish mushroom, but differs from them in the large pores of the tubular layer. The green flywheel should not be confused with the conditionally edible pepper mushroom, which has a yellowish-red color of the tubular layer and the acrid bitterness of the pulp.


Eating an old mushroom that has begun to break down protein can lead to severe food poisoning. Therefore, only young mushrooms are collected for consumption.

The mushroom is well known both to experienced mushroom pickers and to novice fans of quiet mushroom hunting. By its taste, it is highly rated.
