We modify the Press-Schechter formalism to calculate the mass function of gravitationally bounded objects in a local Universe with size $L> 10h^{-1}$Mpc, i.e. separately in voids ($\Omega_{m,L}<\Omega_m$) and superclusters ($\Omega_{m,L}>\Omega_m$). The dependence of the abundance of gravitationally bounded objects on local matter density is analyzed.
