title: Blennione, a green aminobenzoquinone derivative from Lactarius blennius.
abstract: A green pigment, blennione (1), was isolated from fruit bodies of the toadstool Lactarius blennius. Its structure was established by 2D NMR methods and confirmed by a biomimetic synthesis. Compound 1 represents a diphenylquinone derivative, which may be formed biosynthetically from two 3,6-dihydroxyanthranilic acid units.
