The structure of a new naturally-occurring azulene, 1-stearoyloxymethylene-4-methyl-7-isopropenylazulene, obtained from an acetone extract of the blue mushroomLactarius indigo, has been determined by chemical and spectral methods.

    We are aware of only 2 azulenes previously known to occur as such in nature: 1,4-dimethyl- and 1-carbomethoxy-4-methylazulene, which are responsible for the blue color of the oil glands of the liverwort,Calypogeia trichomanis; D.

    Large, mature specimens ofL. indigo contain hardly any latex and only small amounts of pigment, which we found quite intractable.Google Scholar

    SinceL. indigo is uncommon in our area, and young mushrooms are quite inconspicous, we were unable, despite much effort, to secure another such specimen. The discrepancy between these early observations and those made more recently with specimens from Florida might be caused by strain differences.Google Scholar
