Dark mushroom

Dark honey fungus (Latin Armillaria ostoyae ) belongs to the genus of mushrooms Honey mushrooms. In another way, it is also called ground . Grows in mixed forests rich in decaying wood. Likes to settle at the base of tree stumps and fallen trunks.

The yellowish cap of a dark honey agaric reaches ten centimeters in diameter. As the fungus grows, it becomes dense with convexity. Interspersed scales are observed on the cap, and its edges hang down in the form of a white fringed bedspread. The legs of the mushroom are very high, with a thickening at the end. The presence of a ring is noted on the legs.

The emerging spore powder acquires an ocher color. The white pulp is odorless.

Hard spruce honey fungus is the edible and most recognizable species of the genus Openok. In appearance, it is very similar to the edible autumn honey fungus, which has a yellow filmy ring on the leg and a smoother cap with a honey-yellow color. The fungus grows in large groups on dead tree trunks, near rotten pine and spruce stumps. The value of this edible mushroom is low, since it has a tough pulp and a rather bitter taste. The mushroom is decorated with a thin rounded brownish cap, planted on a long cylindrical stem with a white - brown ring. Dark spruce honey fungus actively bears fruit from late summer to mid-autumn.
