Oh my word
I hope you read the wikipedia entry on slime mould
'As long as food is abundant, these slime molds exist as single-celled organisms. When food is in short supply, many of these single-celled organisms will congregate and start moving as a single body. In this state they are sensitive to airborne chemicals and can detect food sources. They can readily change the shape and function of parts and may form stalks that produce fruiting bodies, releasing countless spores, light enough to be carried on the wind or hitch a ride on passing animals.[3]'
'When a slime mold mass or mound is physically separated, the cells find their way back to re-unite. Studies on Physarum have even shown an ability to learn and predict periodic unfavorable conditions in laboratory experiments.[9][10] Professor John Tyler Bonner, who has spent a lifetime studying slime molds argues that they are "no more than a bag of amoebae encased in a thin slime sheath, yet they manage to have various behaviours that are equal to those of animals who possess muscles and nerves with ganglia – that is, simple brains."
Atsushi Tero of Hokkaido University grew the slime mold Physarum polycephalum in a flat wet dish. He placed the mold in a central position representing Tokyo, and he placed oat flakes in the dish corresponding to the locations of other major cities in the Greater Tokyo Area. As Physarum avoids bright light, light was used to simulate mountains, water and other obstacles in the dish. The mold first densely filled the space with plasmodia, then thinned the network to focus on efficiently connected branches. The network strikingly resembled Tokyo's rail system.[11][12]'
So it's an organism, with a brain, that is not a fungus, that re-animates after being broken up and that can ride on your hand and your cat and your shoes and your clothes and probably in your upper respiratory tract!
