The novel dihydroanthracenones (8), (11), and (12), and the biogenetically related anthraquinones (13), (14), and (15) have been isolated from fruit bodies of the Australian toadstool Dermocybe sanguinea (sensu Cleland). The absolute stereochemistry of dermochrysone (8) is inferred by chiroptical comparison with fungal dihydroanthracenones of known chirality. Feeding experiments show that sodium [1-¹³C]acetate is efficiently incorporated into dermochrysone (8) and dermolactone (13) by intact fruit bodies.
