  Let f be a modular form with complex multiplication. If f has critical slope,
then Coleman's classicality theorem implies that there is a p-adic
overconvergent generalized Hecke eigenform with the same Hecke eigenvalues as
f. We give a formula for the Fourier coefficiets of this generalized Hecke
eigenform. We also investigate the dimension of the generalized Hecke
eigenspace of p-adic overconvergent forms containing f.
