The yellow boletus in -language literature is sometimes found under the name “Yunkwill’s boletus”. However, this name is erroneous, because the specific epithet in Latin comes from the word “junquillo”, i.e. “light yellow”, not on behalf of one’s own. Also, yellow boletus in -language literature is often called another species – semi-white mushroom (Hemileccinum impolitum). Other Latin names for yellow boletus may also be found in the scientific literature: Dicyopus queletii var.junquilleus, Boletus eruthropus var.junquilleus, Boletus pseudosulphureus.

In dry weather, as well as when the fungus dries, the surface of the cap becomes dull, and in wet weather – mucous.
