Interpretive Summary: Fungi that parasitize and kill other fungi offer a potential source of new bioactive agents useful to agriculture and medicine. An isolate of Phoma, encountered as a colonist of the persistent fruit body of the wood-decay fungus Hypoxylon, was examined for its ability to produce novel bioactive metabolites. Phomadecalins A-D are reported as new fungal metabolites with activity against gram-positive bacteria.

Technical Abstract: Five new natural products, phomadecalins A-D (1-4) and phomapentenone A (5), have been obtained from cultures of Phoma sp. (NRRL 25697), a fungal colonist isolated from the stromata of Hypoxylon sp. The structures of these compounds were elucidated through a series of 1D- and 2D-NMR experiments. Compounds 1-4 display activity against gram-positive bacteria.
