Grevillines (also spelled grevillins) are a group of natural chemical pigments found in certain fungi, notably the tamarack jack mushroom (Suillus grevillei). There are four members of the class, named grevilline A through D. Grevillines were first isolated from Suillus grevillei, from which they derive their name, and were characterized by Wolfgang Steglich in 1972.
Grevillines are polyphenolic compounds and contain a keto-pyranone group that is similar to hydroquinone. As pigments, they contribute to yellow, orange, and red coloration of the mushrooms they occur in.
Laboratory syntheses of grevillines have been reported.
