Sarcodon subfelleus is a species of tooth fungus in the family Bankeraceae.

It was described as new to science in 1961 by mycologist Kenneth A. Harrison, who initially called it Hydnum subfelleum.

[3] It is found in Nova Scotia, Canada, where it fruits on the ground singly or in groups under spruce and fir.

The spines on the underside of the cap are variable in length, up to a maximum of 7 mm long.

The spores of S. subfelleus are roughly spherical to angular, covered in small, coarse warts (tubercules), and measure 5–6 by 4–5.5 μm.
