 Hydnellum is classified in the family Bankeraceae , which was circumscribed by Marinus Anton Donk in 1961 . The genus was not in Donk 's original family concept , which included only Bankera and Phellodon , genera whose species made hyaline ( translucent ) , and ornamented spores . Donk left Hydnellum in the tribe Hydnelleae of the family Thelephoraceae , along with Sarcodon and Hydnodon . In 1981 , however , Walter Jülich emended Donk 's concept of the Bankeraceae , adding hydnoid genera that produced brown , lobed spores — Hydnellum and Sarcodon .
