Hydnellum scabrosum
Hydnellum scabrosum, also called bitter tooth or bitter hedgehog, is a species of tooth fungus in the family Bankeraceae. It was originally described by Swedish botanist Elias Fries as Hydnum scabrosum in 1836. Finnish mycologist Petter Karsten moved it to the genus Sarcodon in 1881.

Description
The fruit body (mushroom) has a convex to flattened brownish cap up to 12 cm (4+3⁄4 in) across that is covered with brown scales. It can be tinged with pink at the margins and darken with age. The mushroom has yellow-brown spines under the cap that are 5 mm (1⁄4 in) long and 0.3 mm (1⁄64 in) in diameter. They are decurrent to the stem. The pinkish brown stem is 2–12 cm (3⁄4–4+3⁄4 in) high and 1–6 cm (3⁄8–2+3⁄8 in) wide, and has a narrower base that is a characteristic greyish green colour. The flesh is whitish and has a bitter taste, rendering the mushroom inedible. The flesh smells farinaceous or like watermelon when cut.
Similar species. Within the genus it is most closely related to H. fennicum. Sarcodon imbricatus is similar, but the scales do not become as prominent in age. Other similar species include S. fennicus, S. rimosus, S. subincarnatus, and S. underwoodii.

It is found in association with hardwood forests across Eurasia to Japan, as well as North America.
