Xylindein is a quinone pigment, a dimeric naphthoquinone derivative. It is produced by fungi from genus Chlorociboria. This pigment causes green staining of wood infected by the fungi.

Etymology

This pigment was firstly extracted in 1868 by Paul Thénard from wood and resembled indigo, so he called it xylindéine. Combination of xyl- (wood) and indé (indigo) + -ine.[1][2]
