<jats:p>The pigments (9)-(11), the first trihydroxylated tetrahydroanthraquinones from Basidiomycetes, are isolated from an Australian toadstool belonging to the genus Dermocybe and the structure and relative stereochemistry of each one is established by spectroscopy. The absolute stereochemistry of each pigment is determined by synthesis from dihydroxylated tetrahydroanthraquinones of known absolute configuration.
