Boletus junquilleus


Boletus yellow in Russian-language literature is sometimes found under the name "boletus Yunkvilla". However, this name is erroneous, because the specific epithet in Latin comes from the word "junquillo", ie "Light yellow", and not in their own name. Also boletus yellow in Russian-language literature is often called another species - a semi-white mushroom (Hemileccinum impolitum). Other Latin names for boletus can also be found in the scientific literature: Dicyopus queletii var.junquilleus, Boletus eruthropus var.junquilleus, Boletus pseudosulphureus.

The cap of the yellow boletus is usually from 4-5 to 16 cm, but sometimes it can reach 20 cm in diameter. In young mushrooms, the shape of the cap is more convex and hemispherical, and with age it becomes flatter. The skin is smooth or slightly wrinkled, yellow-brown in color. In dry weather, as well as when the fungus dries, the surface of the cap becomes dull, and in wet weather - mucous.

The pulp is dense, odorless, bright yellow, and when cut quickly turns blue.

The leg is thick, tuberous, solid, 4-12 cm high and 2.5-6 cm thick, yellow-brown in color. The surface of the stem does not have a mesh structure, but may be covered with small scales or brown granularity.

The hymenophore is tubular, free with a notch. The length of the tubes is 1 - 2 cm, the color is bright yellow, and when pressed, the tubes turn blue.

Spores are smooth and fusiform, 12-17 x 5-6 microns. Spore olive powder.


Boletus is found mainly in beech and oak forests. The main range of this species is in the countries of Western Europe; in Russia, this species is found in the Ussuriysky region on the territory of the Suputinsky reserve. Collected boletus yellow in the autumn-summer period - from July to October.
