Mushrooms could be extraterrestrial

"The real task with extraterrestrial intelligence will be to recognize it": This is a quote from Terence McKenna. He used it to explain what has been overlooked in almost all discussions of extraterrestrial contact, namely how strange the extraterrestrial is likely to be.

Mushrooms are quite odd if you think about it. They are at the very bottom of the food chain, yet they are everywhere. We don't think of mushrooms as an intelligent species, but mushrooms are a very connected species. Their roots act like an information superhighway that speeds up interactions between a large, diverse population of individuals. It allows individuals who may be widely separated to communicate and help each other out.

Lately, humans have found the key to the blueprints of life namely DNA. Could it be that mushrooms are from outer space and engineered themselves the be able to travel through space and colonize other planets? Their spores are small and light enough to escape the gravity of a planet and be swept by space currents. The casing shell of spores is the hardest organic compound that exists in nature and protects against radiation of all kinds, also radiation in the vacuum of space. If you put all these facts together, it's possible to conclude that the mushroom could be a visitor from outer space.
