Hydnellum subzonatum

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.

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.
