To delete an alias click 'Manage Aliases' from the top menu to display all of the aliases in your domain.

Click the trashcan icon to the left of the alias you wish to delete and confirm this on the next screen to remove the alias.

Removing an alias will not delete any mail from the mailbox. While it cannot be undone, you can re-create the alias if you deleted it accidentally.
