O,.o I believe the fungi kingdom is sentient based on this similar to other insects. Basically if exists in space aswell I believe it has a hive mind like similar species like the bee. But there are good fungi also that keep these invasive species of fungi at bay which we see in rainforests. It could be much more powerful than imagined because it is everywhere in the air on earth and also in space.
Mind-controlling fungus that infects the brains of cicadas can make them kill each other. These mutant critters, dubbed as zombie cicadas, are forced to infect other insects.
