I think I heard somewhere that if not for a few degrees in temperature human beings would be plagued by many fungal diseases. But because of our body temperature (and immune system) they find it very hard to live in our bodies. I'm wondering if global warming will accelerate the adaption of fungi to higher temperatures and therefore potentially allowing a new species to invade us. The future is fun and holds many things to look forward to. Perhaps we can become one with the mushrooms some day.
