Xerocomic acid

Chemical compound

Xerocomic acid is a red-orange pigment found in fungi of the order Boletales. It is the precursor to variegatic acid, and is preceded by atromentic acid and atromentin. As an example, it is isolated from Serpula lacrymans. It is soluble in methanol. An oxidase acting on xerocomic acid is responsible for the "bluing" reaction seen in mushrooms.
