The bleeding tooth fungus grows in Europe and North America. While young, the fungus looks like it is oozing blood. The red liquid is actually an anticoagulant. It lives on the roots of conifer trees and exchanges nutrients in a mutually beneficial relationship.Now, I know that “bleeding tooth” sounds incredibly appetizing, but while they aren’t toxic, they are considered inedible.
Hydnellumpeckiiestablishes a mutualistic relationship with the roots of certain trees (referred to as "hosts"), in which the fungus exchanges minerals and amino acids extracted from the soil for fixed carbon from the host. The fungus grows a sheath of tissue around the rootlets of a broad range of tree species, in an intimate association that is especially beneficial to the host (termed ectomycorrhizal), as the fungus produces enzymes that mineralize organic compounds and facilitate the transfer of nutrients to the tree.
