A fungus is able to search through a maze and apparently remember the route. Is it sentient?

EDIT: Your concern as to whether I was snarky in my response glossed over the fact that there is an answer. Let's talk about that instead of proving my "snark" as the more important yet correct part.

Why are you trying to prove that fungi are sentient? You're just being disingenuous. The core issue is the fact that we kill and eat animals that feel pain and emotions (the "vegan debate", whatever), something that seems wrong at face value. How about addressing that instead of hiding behind annoying semantics? It's obviously what the OP meant.

Look at your sibling comment for an example of a comment made by someone who actually cares about discussion and not winning stupid word wars. You both said the same thing in essence, but they don't come off as a prick.
