  The gravitational collapse of a spherical distribution, in a class of f(R)
theories of gravity, where f(R) is power function of R, is discussed. The
spacetime is assumed to admit a homothetic Killing vector. In the collapsing
modes, some of the situations indeed hit a singularity, but they are all
covered with an apparent horizon. Some peculiar cases are observed where the
collapsing body settles to a constant radius at a given value of the radial
coordinate.
