Hughes and Jon Parkin threatened up front early on for Forest Green, but the visitors were unable to take advantage of their early dominance.
Phil Smith had to remain alert in the Aldershot goal as Hughes continued to push for an opener, but the forward's finish lacked power, giving the keeper a comfortable save, before denying Parkin a few minutes later.
The miss proved costly a couple of minutes later as the visitors won a corner down the other end of the pitch, allowing Rob Sinclair to deliver the ball for Hughes to head in the equaliser.
Anthony Tonkin almost set up a second for the home side, but his ball into the box failed to find any of his teammates.
Dan Fitchett provided a late threat for the hosts after replacing Williams for the final 10 minutes, but was unable to put the team back in front late on, ensuring that the match finished in a draw.
