The structure of a toxic principle, m. p. 273° (decamp), produced by Penicillium islandicum SOPP, D strain, was examined. It was assumed to be a compound having structure similar to flavoskyrin and rugulosin, and tentative structures (I) and (II) were forwarded. The formula (I) seems to be more possible. The name luteoskyrin was given to this substance.
