Mushrooms are fascinating. Can't blame this guy for digging them. Did you know that mushrooms (fungi to be precise) are not a plant and are not an animal? They are so special that they have their own biological kingdom. (https://en.wikipedia.org/wiki/Fungus)
Please don't be an asshole on HN. That poisons the culture and is the leading thing we want to avoid here.
If you know more than someone else, please share some of what you know, so the rest of us can learn. If you don't want to do that, that's fine, but then please don't post. Supercilious putdowns don't help and aren't nice.
Edit: we've had to ask you many times not to break the site guidelines like this. If you keep it up we're going to have to ban you again, so please review the guidelines and please fix this.
Please don't be an asshole in HN comments. Posts like this are extremely damaging. If you know more than someone else, that's a great chance to share some of what you know, so we all can learn. If you don't want to do that, that's fine, but then please don't post. Damaging the commons, as you did here, is not a good choice.
Also, can you please stop posting unsubstantive and/or snarky comments in general? You've done it repeatedly, unfortunately. We ban such accounts because we're trying for a different sort of culture here. If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
