Fungoids aren't a Hivemind!
A patch for Vanilla Races Expanded - Fungoid.
This mod removes the "Mind Coalescence" gene from the Fungoid xenotype (the gene that makes fungoid pawns share moods and suffer any mental break together) and replaces it with the vanilla "Psy-sensitive" gene. There appeared to be demand for this to be implemented and should be useful to those that do not want to deal with this aspect of the standard fungoid xenotype.
You may also see a slight performance improvement in saves with many Fungoid pawns on the map as the "Mind Coalescence" gene did have a slight performance impact whenever it scanned to synchronize the moods of the Fungoid pawns.
This can be loaded in an existing save, however it will only affect newly spawned Fungoid pawns.
