Fungi come in all sizes, shapes, and colors, and their range of habits and habitats is just as diverse.

It's fungi's ability to grow just about anywhere that makes it so amazing. If you name a hostile environment there's more than likely some form of mushroom or yeast that will not only grow there but prefer it over anywhere else. An extreme version of this is when researchers stuck their instruments into one of the most poisonous places on earth and found not only a species of mushroom growing there but one that actually appears to be feeding on the toxicity. How nasty is this place? Well, all you need to say is one word to shudder at the thought: Chernobyl.
But strangeness and fungi don't end with radiation-feasting mushrooms, for there are quite a number of them that feast on other things -- including animals. Nematophagous fungi, for instance, grow miniscule rings that, if a nematode happens to squirm into one, rapidly contract, trapping the unfortunate lunch ... I mean 'worm.' If this makes you a bit nervous take a bit of consolation in that the popular oyster mushroom is also a nematode killer – and it's also tasty, so while it eats them we also eat it.
