Rodney Bernard Greene appeals the district court’s order revoking his supervised release and imposing a six-month custodial sentence. Greene has been discharged from federal custody, his sentence did not include a term of supervised release, and there are no continuing collateral consequences from the district court’s revocation order and imposition of sentence. We therefore dismiss Greene’s appeal as moot. See Spencer v. Kemna, 523 U.S. 1, 10, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998). We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED
