The name “mushroom Alcohol” for 1-octen-3-ol comes from it first isolation by Murahashi in 1936 and 1938 from crushed matsutake mushrooms. [5][6]A recent study on volatiles of this mushroom has shown this compound is only produced upon tissue disruption.[7] This alcohol is found in many other mushrooms where it may play a role as an antifeedant.[8]
