We show that separately harmonic functions and pluriharmonic functions in Cn can be characterized by a finite number of mean-value conditions over boundaries of ellipsoids or distinguished boundaries of polydisks. This is a generalization of the Delsarte-Lions characterization of harmonic functions and of the Morera theorem for holomorphic functions.
