N2  - cis,cis-4,4&#8242;-Dihydroxyflavomannin 6,6&#8242;-di-O-methyl ether A (4), 10,10&#8242;-dihydroxy-4,4&#8242;-dioxoflavomannin 6,6&#8242;-di-O-methyl ether A (6) and 4&#8242;,10-dihydroxy-4-oxoanhydroflavomannin-9&#8242;,10&#8242;-quinone 6,6&#8242;-di-O-methyl ether A (7), new coupled dihydroanthracenones, and bierythroglaucin (8), a novel dimeric anthraquinone, have been isolated along with emodin (9) and citreorosein (&#969;-hydroxyemodin) (10) from the purple-brown fruit bodies of the Australian Dermocybe sp. WAT 21566. The structures and relative stereochemistry of the new natural products (4) and (6)&#8211;(8) are deduced by spectroscopic and chemical methods.
