Characterization of new illudanes, illudins F, G, and H from the basidiomycete omphalotus nidiformis

This investigation reports the isolation and characterization of three new illudane-type sesquiterpenes (1-3) from Omphalotus nidiformis, a Basidiomycete native to Australia and usually found in eucalypt forests in the eastern region of the country. These compounds are closely related to metabolites of North American and European Omphalotus species.
