Magnetotransport measurement has been made on unidirectional quasiperiodic lateral superlattices in which electrostatic potential is modulated in Fibonacci sequence. We have observed (1) superposition of a series of commensurability oscillations each arising from an ``average period'' belonging to one of the self-similar generations and (2) geometric resonance of open orbits composed of segments of cyclotron orbits repeatedly diffracted by the quasiperiodic superlattice.
