The structure of cristatomentin ( 5 ), the green pigment of the toadstool Albatrellus cristatus , has been elucidated by MS studies and a comparison of the NMR spectrum of 5 with the data for cristatic acid ( 1 ) and albatrellin ( 6 ). The furylbenzoquinone chromophore of 5 may be derived from 1 and 2‐ O ‐acetylatromentin ( 4 ), which co‐occur with cristatomentin in the fungus.
