Hydnum umbilicatum Look-alikes
 |
 |
| Hydnum repandum (above), is difficult to separate from H. umbilicatum, but is generally larger, bruises deep orange and lacks the abruptly deep navel on the cap. | Clitocybe gibba (Clitocybe infundibuliformis) (above) is differentiated from H. umbilicatum by having gills instead of spines or teeth. |
