  We study several aspects of the $N=1$ super Liouville theory. We show that
certain elements of the fusion matrix in the Neveu-Schwarz sector related to
the structure constants according to the same rules which we observe in
rational conformal field theory. We collect some evidences that these relations
should hold also in the Ramond sector. Using them the Cardy-Lewellen equation
for defects is studied, and defects are constructed.
