Scopes reduction and Morita equivalence classes of blocks in finite classical groups II

We extend our work of [J. Algebra 230 (2000) 378–423] on unipotent blocks of classical groups to blocks of orthogonal groups containing characters labelled by degenerate symbols. We also show that, for classical groups in the linear prime case, there are only finitely many Morita types of unipotent blocks with a given defect group.
