It is characterized as having an "extremely nauseating" taste. Its spores are roughly spherical to oblong, measuring 5–6 by 4–5 μm.

Sarcodon calvatus, commonly known as the robust hedgehog, is a species of tooth fungus in the family Bankeraceae. It was described as new to science in 1964 by mycologist Kenneth A. Harrison, who initially called it Hydnum calvatum. He transferred it to the genus Sarcodon in 1984. The pale to pinkish or tannish cap can grow up to an extreme of 35 centimetres (14 in) across. The surface stains blue-green to black in KOH. It is found in North America.

Phellodon fibulatus is a species of tooth fungus in the family Bankeraceae. Found in the United States, the fungus was described as new to science in 1972 by Canadian mycologist Kenneth A. Harrison. It is one of the few species of Phellodon that possess clamp connections in its hyphae.

Hydnellum subzonatum is a tooth fungus in the family Bankeraceae. Found in Nova Scotia, Canada, it was described as new to science in 1961 by mycologist Kenneth A. Harrison. Its small fruitbodies grow as fused caps, with individual caps measuring 1.3–5 cm (1–2 in) in diameter. Initially white, they turn light brown with a somewhat darker center, and are faintly zonate (with a pattern of rings). The grayish-blue spines on the cap underside are up to 3 mm long. Growing fruitbodies have an unusual hoary (grayish-white) appearance. The spores are oblong to almost square, measuring 3.5–4.5 by 3.4

Hydnellum septentrionale is a tooth fungus in the family Bankeraceae. Found in Michigan, it was described as new to science in 1964 by Canadian mycologist Kenneth A. Harrison.

Hydnellum scleropodium is a rare species of tooth fungus in the family Bankeraceae. It was described as new to science in 1964 by Canadian mycologist Kenneth A. Harrison. The fungus has been collected in Tennessee, North Carolina, and Nova Scotia, in both mixed and coniferous forest. Its fruitbody has an irregular, brownish cap measuring 10–25 cm (4–10 in) wide. The sclerotium-like stipe measures 3–9 cm (1.2–3.5 in) long by 2–4 cm (0.8–1.6 in) thick, and roots into the ground. The flesh has a strong, fragrant odor. Spines on the cap underside, blue in color, are up to 11 mm long.

Hydnellum nigellum is a tooth fungus in the family Bankeraceae. Found in Nova Scotia, Canada, where it grows under spruce, it was described as new to science in 1964 by Canadian mycologist Kenneth A. Harrison. The fruitbodies of this fungus are small, measuring 3–6 cm (1.2–2.4 in) in diameter, and black.

Hydnellum multiceps is a rare species of tooth fungus in the family Bankeraceae. Found in Nova Scotia, Canada, it was described as new to science in 1961 by mycologist Kenneth A. Harrison.
