Hydnum umbilicatum, commonly known as the depressed hedgehog,[3] is a species of tooth fungus in the family Hydnaceae.

It was scientifically described in 1902 from New York by American mycologist Charles Horton Peck.

[6] Hydnum umbilicatum has been found to be associated with pines.

[7] Can be confused with Hydnum repandum, also known as the Wood Hedgehog.

These two can be distinguished by their size and distribution, with H. repandum being a much larger species found in Europe.
