Oyster mushrooms

"It has been recently found that, even though the commonly cultivated oyster mushroom is saprophytic, it has its carnivorous side. The mushroom has been found to produce cells which bear tiny droplets of a substance that is toxic to nematodes (a tiny worm). If one of these hapless worms gets splashed with this poison, it becomes paralyzed. The mushroom hyphae have been seen to home in on the worms and eat them alive! This doesn't have a whole lot to do with the process of cultivating mushrooms, but it does point out the fact that we are constantly learning new things about how mushrooms live.
