The author starts out depicting themselves as some sort of cloning scientist... and clearly not only isn't that, but isn't very informed on mushrooms.

Many, if not most, wood-decaying mushrooms (those that break down dead wood) rely on killing nematodes to supply nitrogen, which is otherwise short supply in their diet. They use adaptations that resemble glue pads, tripwire nooses, or even hydro-pumped harpoons to trap the "helpless nematodes" (oh, the humanity! Won't somebody think of the worms?). It's not rare; it just wasn't known until circa 2000. And it's not unique to the invading fungus; our native oysters were where this discovery was first made.

Spare me the "poor defenseless prey animal" BS, and tell me about the known or suspected ecological impact - the reduction in fungal diversity is relevant, at least.
