A species of Milk-caps.

The Tacked Milkcap mushroom, found either alone or in clusters beneath birch and conifer trees, has had its entire genetic makeup sequenced by researchers. Its initial description was provided in 1838 by the Swedish mycologist and botanist Elias Magnus Fries, appearing in his work Epicrisis Systematis Mycologici.
