Is the Bleeding Tooth Fungus really bleeding?

If you come across a young Bleeding Tooth fungus (Hydnellum peckii) you might be surprised by its appearance. Oozing out of pores on the top of this fungus is a gooey red liquid. Although you may think it has been damaged or hurt, don’t worry because it isn’t really bleeding.

The red liquid that seeps out of the top of the Bleeding Tooth fungus is perfectly normal. This red sap emerges from the fungus because of high root pressure, something known as guttation. As the fungus grows older, the pressure eases and the Bleeding Tooth fungus will turn brown.
