The not edible bumpy fragrant hedgehog, whose grayish-brownish cap is velvety, its spines are slightly purplish.

Note: The genus name was created by Petter Karsten in the same year he placed this species here. The meaning comes from Phell - cork and don - tooth. The niger species name simply means black. The word "negro" also originates from this.

Species description: In 1815, the great Swedish mycologist Elias Magnus Fries described this species and gave it the name Hydnum nigrum. In 1881, the Finnish mycologist Petter Adolf Karsten (1834-1917) transferred it to the Phellodon genus, as Phellodon Niger.
