Mi-Go

"Mi-Go are a fictional race of extraterrestrials created by H. P. Lovecraft and used by others in the Cthulhu Mythos setting. The word Mi-Go comes from 'Migou', a Tibetan word for yeti. The aliens are fungus-based lifeforms which are extremely varied due to their prodigious surgical, biological, chemical, and mechanical skill. The variants witnessed by Akeley in 'The Whisperer in Darkness' look like winged human-sized crabs.

"Mi-Go are first named as such in Lovecraft's short story 'The Whisperer in Darkness' (1931). However, since they are described in this story as 'fungi' that come 'from Yuggoth,' they can be considered an elaboration on earlier references to alien vegetation on dream-worlds in Lovecraft's sonnet cycle Fungi from Yuggoth (1929–30)."
