The bleeding tooth fungus looks kind of like a wad of chewing gum that leaks blood like a rejected prop from The Shining.
They're also called the strawberries and cream, the red-juice tooth, and the devil's tooth. This thing looks like a tooth, and it looks like it sweats blood.
Oh, and they are listed as "inedible," which implies that someone attempted to eat one at some point. On the other hand, the bloodlike substance has anticoagulant and antibacterial properties. It's nature's next penicillin!
