I agree that it's great to find out, but your ignorance (forgive me) is a symptom of a bigger problem. Mycologists first got a clue back in the 1970s that land plants were enabled by fungi in the glomeromycota that need a photosynthesizing partner to live, and it came from the fossils in the Rhynie chert. They've even drawn some (very poorly known) cartoons about this. When I got involved with mycorrhizal research as a botanist in the 1990s, I spent a lot of time convincing other botanists that the field matters, and I still do. It gets frustrating that something so fundamentally weird, cool, and important is so systematically ignored that a crappy version of it gets transmitted as news on BoingBoing.
The problem is that US and England are mycophobic societies: to us, fungi are scary and icky, and unless we're talking about yeast (bread and alcohol), we generally don't want to deal with them at all. This attitude isn't shared with other nations; much of Europe, Russia, and China have no problem eating fungi and working with them. For us, though, our cultural phobia has huge consequences beyond not eating mushrooms. We're generally clueless about what mycorrhizal fungi can and can't do: at best, most people treat spores as fairy dust to sprinkle on their gardens to make them grow better. Worse, there's a huge, untapped potential role for using fungi for things like remediating industrial waste sites and cleaning up sewage, but a combination of a few badly written patents and (more generally) our societal phobia keeps us using the expensive, inefficient methods we generally have. For anyone who wants to know more, I strongly advise reading Stamets' Mycelium Running. That's a mind-blowing book too, and it has the virtue of being accurate.
And please, please, get over both the phobia and the ignorance. Fungi can be icky, but without them plants wouldn't be here and neither would we.
