A new perylenequinone, 4,9-dihydroxy-1,2,11,12-tetrahydroperylene-3,10-quinone (1), together with three known compounds, have been isolated from the ethanolic extract of the fruit bodies of Bulgaria inquinans, and their structures elucidated on the basis of the spectral data and comparison with the literature.
