David Dietle wrote a highly entertaining post on Cracked about the 10 Creepy Plants That Shouldn't Exist. The list starts off with a bang with this one:
#10. Bleeding Tooth Fungus
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. Whoever is in charge of naming scary bullshit
seems really insistent that this thing looks like a tooth, while mostly skirting over the fact that it freaking 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! All you have to do is lick it. Go ahead.
