Hydnum umbilicatum 

Hydnum umbilicatum Peck 

 Like its ‘sister’ Hydnum repandumHydnum umbillicatum has spines beneath its cap. However, Hydnum umbilcatum has a small, almost circular cap with a depressed center (which reminds some of us of a belly button). Found in boggy areas with moss. Hydnum repandum's caps are relatively large and asymmetrical, and their stems are relatively short compared with Hydnum umbilicatum. The ‘Belly-button Hydnum’ is in the Hydnaceae family of the Cantharellales order.
