Does the spell destruction affect undead?

[nutritious_nutrias]

In the monster manual for pathfinder it says undead are immune to spells that cause fortitude saves. so my gm said the spell destruction which has the monster make a fortitude save could not work on undead....even though in the description of the spell it says "holy fire".

Is there official ruling on this?

Target one creature
