Thelephantins are a group of pigments found in the inedible mushroom Thelephora aurantiotincta. Chemically, they are classified as polyphenols and terphenyl derivatives.

Three variants (thelephantin A, B, C) have been elucidated by high-resolution 2D nuclear magnetic resonance, mass spectroscopy, infrared and ultraviolet spectra as well as an acetylated congener of thelephantin A.[1][2] The structure of telephantin G was revised and confirmed by total synthesis.[3]
