Six new metabolites, citreopyrones A-C and D-F, have been isolated from the mycelium of a hybrid strain KO 0092 derived from P. citreo-viride B. IFO 4692 and 6200, and KO 0141 derived from P. citreo-viride B. IFO 4692 and P. pedemontanum IFO 9583. Their structures have also been elucidated on the basis of their spectral data and some chemical evidence. Citreopyrones A, B, and C inhibited the growth of hypocotyls of lettuce seedlings.
