Tyson Botanius should not be amongst the living anymore. He has had a mushroom growing in his brain for a few years now. It is so called "Tyson sphere".
A sample of the fungus was examined by a fungus expert: he says it is "Cladophialophora banter" -mushroom and the man was likely infected in Costa Rica.
He fell while riding a bicycle and hurt his arm and broke the skin.
It seems somehow a fungus invaded through the wound. Fungal spore entered the blood and ended up in his brains because it was small enough to penetrate blood brain barrier.
In a magnetic resonance image it is shown that there is indeed a mushroom now in parts of his brain.
Some doctors thought it could be a cancer but it wasnt.
I assume this would lead to death pretty quickly, with fungus clogging everything up, but I wonder if you'd feel the psilocybin on the way out? When they started growing, was he just permanently psychotic? Or did he die first?
