Hydnellum rusty

Hydnellum rusty (Hydnellum ferrugineum) is a fungus belonging to the Bunker family and the Hydnellum genus.

External description

The fruiting body of rusty hydnellum is hat-stem.

Hat. The diameter of the cap is 5-10 cm. In young specimens, it has a clavate shape; in mature mushrooms, it becomes reverse conical (it is funnel-shaped or flat in some specimens).

The surface is velvety, with many irregularities, often covered with wrinkles, whitish in young mushrooms. Gradually, the surface of the cap becomes rusty brown or pale chocolate. It clearly shows purple droplets of a protruding liquid, which dries up and leaves brown spots on the cap of the fruiting body.

The edges of the cap are even, white, and brown with age. The mushroom pulp is two-layered, near the surface it is felt and loose. It is best developed near the base of the stem, and in this area it has a lighter color. In the center of the cap of rusty hydnellum, the texture of the tissues is leathery, cross-zoned, fibrous, rusty-brown or chocolate shade.

During growth, the fruiting body of the fungus, as it were, 'flows around' encountered obstacles, for example, twigs.

Hymenophore characteristics. Spiny hymenophore, consisting of spines descending slightly down the pedicle. at first they are white, gradually becoming chocolate or brown. They are 3-4 mm long, very brittle.

Leg. The height of the rusty gidnellum leg is 5 cm. It itself is completely covered with a rusty-brown soft cloth and has a felt structure.

Microscopic signs. Thin-walled hyphae have slightly thickened walls, do not contain buckles, but there are septa. Their diameter is 3-5 microns, there is a minimum color. Near the surface of the cap, you can see a large accumulation of brownish-red hyphae with blunt ends. Rounded warty spores are characterized by a slightly yellowish color and 4.5-6.54.5-5.5 microns in size.

Season and habitat of the mushroom

Hydnellum rusty (Hydnellum ferrugineum) grows mainly in pine forests, prefers to develop on depleted sandy soil and is picky about its composition. Widely distributed in coniferous forests, with spruce, fir, pine. Sometimes it can grow in mixed or deciduous forests. The fungus of this species has the property of reducing the concentration of nitrogen and organic matter in the soil.

Rusty hydnellum thrives in old lingonberry forests with white moss, in the middle of old dumps along forest roads. Grows on soils and substrates. These mushrooms often surround the bumps and pits formed by heavy equipment. You can also see rusty hydellums next to forest paths. The fungus is ubiquitous in western Siberia. Fruiting from July to October.

Similar types and differences from them

Rusty gindellum is similar to gindellum blue, but very different from it in section. The latter has many blue areas inside.

Another similar species is Gindellum Peka. Mushrooms of these species are especially confused at a young age, when they are characterized by a light color. The flesh of Gidnellum Pek becomes especially sharp in mature specimens, and does not acquire a purple hue on the cut.

Hydnellum spongiospores is similar in appearance to the described species of fungi, but it grows only in deciduous forests. It is found under beeches, oaks and chestnuts, characterized by a uniform edging on the stem. There are no droplets of red liquid on the surface of the fruiting body.

The color of the mushroom is similar to rusty iron, which is why it got that name.
