  We investigate the nature of a sample of star cluster candidates detected as
stellar overdensities towards the Galactic anticentre. Taken from the catalogue
of Froebrich, Scholz, and Raftery (FSR), the sample contains 28 star cluster
candidates located within $|\Delta\ell|=20^\circ$ of the anticentre. These are
all the candidates in that sector classified by FSR with a high probability of
being star clusters. Our main goals are to determine the fraction of such
candidates that are unknown star clusters, to derive their astrophysical
parameters, and to investigate the relationship of cluster parameters with
position in the Galaxy. When photometric and radial distribution properties are
considered together, an important fraction of the stellar overdensities with a
fluctuation level $\ga3\sigma$ are shown to be star clusters. Thus, catalogues
of star cluster candidates, coupled to the present kind of study, are an
important source for identifying unknown open clusters. Such efforts affect the
understanding of the star-formation rate, cluster dynamical evolution, and
Galactic structure, among others.
