Four cadinane-type sesquiterpenes and four 13-carbon γ-lactones, together with three known compounds, were isolated from cultures of the basidiomycete Trichaptum pargamenum. Their structures were elucidated on the basis of extensive spectroscopic methods. The absolute configurations of two of the cadinene type sesquiterpenes 1 and 3 were confirmed by single crystal X-ray diffractions.
