We incorporate linear mode conversion in wave-kinetic theory when the incoming waves are incoherent, as occurs when the wave sources are turbulent processes or thermal emission. Mode conversion takes place when the rays of either wave mode cross the {ital mode} {ital conversion} {ital manifold} in the ray phase space. Jump conditions are derived which match the incoming and outgoing wave actions across the mode-conversion manifold, leading to a pair of coupled wave-kinetic equations. We also discuss how incoherent linear mode conversion acts as a source of wave entropy.
