We review the accelerating (mainly, dark energy) cosmologies in modified gravity. Special attention is paid to cosmologies leading to finite-time future singularities in F(R), F(G) and F(R,G) modified gravities. The removal of the finite-time future singularities via addition of R2-term which simultaneously unifies the early-time inflation with late-time acceleration is also briefly mentioned. Accelerating cosmology including the scenario unifying inflation with dark energy is considered in F(R) gravity with Lagrange multipliers. In addition, we examine domain wall solutions in F(R) gravity. Furthermore, covariant higher derivative gravity with scalar projectors is explored.
