Culture filtrates of Fusarium monoliforme contain 16α-hydroxy-(−)-kauran-19-al (8) and 16α-hydroxy-(−)-kauran-19-oic acid (9)-two diterpenoids related to the intermediates in the biosynthesis of gibberellins. The previously described 7,13-dihydroxykanrenolide (10) is an endogenic metabolite of the fungus. From the mycelium extracts three C28-sterols were isolated including the hitherto unknown 5α-
