Description	Let k be an algebraically closed field of characteristic p and G a finite group such that p divides the order of G. We compute all almost split sequences over kG when kG is of finite representation type, or more generally, for a finite dimensional k-algebra given by a Brauer tree. We apply this to show that if and are stably equivalent k-algebras given by Brauer trees, then they have the same number of simple modules.
