Oyster mushrooms are known predators of nematodes. They are not mentioned in the above wiki, but their own confirms that they exploit toxins to capture and feed.

This is part of the issue with the invasive Golden Oyster in North America, their mycelium paralyze and kill nematodes very efficiently which (directly or indirectly) leads to outcompetition of native fungii. https://news.ycombinator.com/item?id=47536102

They're commonly foraged, and naturally present a curious question of whether they're a vegan food since they're carnivorous.

I thought about this and looked for a definition. It’s all about animal products, presumably making this fungus vegan?

There is an ISO definition of vegan (23662:2021) but it seems to cost $88 and then I emerged from the rabbit hole.

Here’s the iso as pdf (it only apply to food): https://cdn.standards.iteh.ai/samples/76574/4b2534a5a3934ca1...

Most vegan adhere to a more practical and pragmatic definition, like this one, from the association founded by the veganism-word initiators:

Thanks.

And wow yes. ‘I’m a ISO standard vegan’ isn’t something I’ve heard and it has probably never happened.
