Bleeding Tooth Fungus (Hydnellum peckii) is an indeterminate toothed mycorrhizal mushroom that associates with Pine. It is inedibly tough and bitter, but not poisonous to consume (or touch). The red droplets are Guttation, or essentially mushroom sweat from the fungus growing quickly. It can be used to dye fabrics blue to green. #bleedingtoothfungi #hydnellum #hydnellumpeckii #guttation #blood #blooddrops #droplets #mycology #fungi #fascinatedbyfungi #sciencetok #mushtok | Fascinated By Fungi

Found a patch of Hydnellum peckii, also known as the Bleeding Tooth Fungus. This bizarre mushroom gets its name from the red exudate it produces, resembling blood. Hydnellum peckii are not known to be poisonous but are considered inedible! Photos and filming by Pamela Kryskow | Paul Stamets

As is often requested, I tried licking a Bleeding Tooth fungus (Hydnellum peckii). The bloody looking droplets are guttation or mushroom sweat. The red color comes from polyphenols and taninins in the droplets of metabolite. Despite its somewhat daunting and delicious appearance this is an inedible mushroom, because it is very bitter and the texture is very tough. Here I demonstrate that first hand. Trust me when I saw this bitter and gross, not recommended. There’s nothing dangerous about doing
