What does Collybia chestnut look like?

Description of the cap

Buttercollibia has a hemispherical cap, up to 12 cm in diameter, which opens with age, leaving a small mound in the center. The edges are wavy and raised. The surface is covered with an oily skin, which turns different colors depending on weather conditions. In dry weather it turns brown-red, yellow-brown or coffee color. After rain the cap is much darker.

Important! The pulp is watery, whitish-yellow. The hygrophane cap swells and increases in size after rain.

The spore layer is covered with uneven plates with jagged edges. When young they are painted white; in adult specimens they become gray-yellow. Collibia oilseed reproduces by snow-white elongated spores, which are located in light pink spore powder.

Description of the leg

The leg is cylindrical, widens towards the bottom, up to 10 cm in height. Hollow, its pulp is fibrous, colored brown.

Is the mushroom edible or not?

The variety is classified as conditionally edible, since butter colibia does not have a pronounced taste. When mechanically damaged, the pulp emits a faint odor of dampness or mold. Therefore, before preparing dishes, mushrooms are soaked and boiled. Only the upper part of young specimens is used in cooking, since the pulp in the stem is hard and fibrous. Prepared specimens are good fried, stewed and canned.
