Isoxerocomic acid is a red-orange pigment found in Boletales. It is the precursor to variegatic acid, and is preceded by atromentic acid and atromentin.[2] As an example, it is isolated from Serpula lacrymans. It is soluble in methanol. It is the isomer of xerocomic acid and precursor to xerocomorubin.[2][3]
