Interpretive Summary: Fungi that parasitize and kill other fungi offer a potential source of novel antifungal agents useful to agriculture and medicine. The fungus Sporormiella minimoides NRRL 37629, encountered as a colonist of a wood decay fungus growing on a dead hardwood branch, collected in a subalpine forest in Hawaii County, Hawaii, was examined for its ability to produce antifungal agents and other bioactive metabolites. Sporminarin A is reported as a new fungal metabolite with significant antifungal activity against Aspergillus flavus.

Technical Abstract: Cultures of a fungicolous isolate of Sporormiella minimoides afforded two new polyketide metabolites which we have named sporminarins A (1) and B (2). The planar structures of 1 and 2 were elucidated by analysis of NMR and MS data, and by chemical methods. Sporminarin A (1) exhibited significant antifungal activity against Aspergillus flavus.
