Weather
Just after accepting [this desk] as part of the turnover process; Aircraft X sent an ACARS indicating they had just encountered severe turbulence at FL240 just west of ZZZZZ. I asked the crew to confirm severe; which they did; and we ended up conducting an ARINC call. The crew informed me they encountered SEVERE TURB; +/- 40kts; loss of control; roll to the left and right of up to 40 degrees and a loss of altitude of 200 to 300 feet. The flight was planned at FL340; above the forecast turbulence ZZZ area; which was FL260 - FL330 [along that route of flight] with remarks on the release. During the subsequent 'Call Me'; the crew indicated ATC informed them the best rides were FL240; so they halted their climb at FL240. After the severe event they descended to FL200 where they reported it was smooth. The crew informed me there were no injuries; AC (aircraft) damage; and everyone was seated including the FA's (Flight Attendants) during the severe event.
Dispatcher reported receiving a flight crew message indicating a temporary loss of aircraft control during severe turbulence encounter.
