It was found by Southern Oregon University professor Robert Coffan in the Rogue River in the U.S. state of Oregon.[2] Coffan found the mushroom in 2005, and his colleagues Darlene Southworth and Jonathan Frank in the biology department at Southern Oregon University confirmed that the mushroom was a unique discovery.[3]
The mushroom's stipe appears to be quite strong, and is anchored up to 1.6 feet (0.5 m) deep in sediment, in order to stand up to the fast-moving river currents where it is primarily found.[1]
