Sarcodon subfelleus

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.[2] He transferred it to the genus Sarcodon in 1984.[3] It is found in Nova Scotia, Canada, where it fruits on the ground singly or in groups under spruce and fir. The type collection was made in Glenmont, Kings County.[2]

The fungus makes fruit bodies with convex to irregularly shaped caps measuring 4–17 cm (1.6–6.7 in) in diameter, supported by a stout stipe measuring 1–9 cm (0.4–3.5 in) long by 1–4 cm (0.4–1.6 in) thick. The spines on the underside of the cap are variable in length, up to a maximum of 7 mm long. They are light grayish-brown with white tips, but darken when bruised. 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.[2]
