Seven new bis(naphtho-γ-pyrone) derivatives, named ustilaginoidins D (8), E (9), F (10), G (11), H (12), I (13), and J (14), were isolated in addition to ustilaginoidins A (1), B (2), and C (3) from Claviceps virens. Their structures were elucidated chiefly on the basis of nuclear magnetic resonance data.
