From a mutant of Diplodia macrospora , chaetoglobosin M (5) , ergosterol, β‐sitosterol, and a third sterol, most likely stigma‐5,7,22‐trien‐3β‐ol, were isolated. Metabolite 5 is a new member of the ( 1H ‐indol‐3‐yl)‐substituted 10,11‐diethyl‐10,11‐dinorcytochalasans. Its structure was determined by 1 H‐ and 13 C‐NMR and mass spectrometry.
