Depending on how you look at it, the bleeding tooth mushroom can appear quite eerie or, on the contrary, tasty. As a juvenile, it's easily identifiable because it oozes bright-red, bloodlike juice (technically xylem sap droplets) from pores in its white cap. But this ability to "bleed" dissipates as it gets older; with time, it becomes an average-looking, grayish-brown mushroom. The bleeding tooth can found in North America, Europe, Iran, and Korea.
