Friendly reminder that cooperation is mutually beneficial and the mathematical solution to the prisoner's dilemma is to cooperate but not be a pushover.
That fungus would eat the tree if it had the abiliry
Don't ascribe motivations to biological processes.
That fungus wouldn't eat the tree because it doesn't eat the tree. There are tree eating fungi but that is not one of them.
That fungus is proof of cooperation being mutually beneficial and evidence of how "altruism" works out in favor of the cooperators.
Based on what?
According to my quick research, symbiotic fungus doesn't fruit unless the tree is in trouble. That tree seems fine, so then the fungus probably isn't good for the tree
Where on earth are you researching to come to that conclusion? Mushrooms overwhelmingly fruit based on climatic conditions. If the weather is right, they fruit. And it is well established that mycorrhizal fungi are good for the trees and other plants they have symbiotic relationships with, which is why fungal inoculation is becoming increasingly popular. It's also why they are called symbiotic, and not parasitic.

Looks like that's just morels that behave that way
I'd be wary of using a foraging blog as a source of information, there is a lot of misinformation that gets around in foraging communities.
In this case the information is mostly okay, with some caveats. Morels certainly don't fruit exclusively when a tree is dying (this blog doesn't quite assert that, but it does highly emphasise the dying trees part so I can see how you would take that away) and it's important to note that the trees death was caused by a separate parasitic fungi and not the morels. They're fruiting in an attempt to spread their spores before they go down with the ship, so to speak.
Personally I'm a little skeptical about the old timer stories and the conclusion drawn from them, but I live on a different continent with completely different species of fungi so I couldn't say for sure. Over here our most prolific morel seasons are always when the temperature is mild, there have been good rains and the forest is happy and healthy. From an evolutionary perspective, this makes perfect sense. The fungal spores have a much better chance of establishing new colonies when resources are plentiful. A symbiotic mushroom that only fruits when all its symbionts are dying around it is going to be naturally selected out of existence.

I don't think that's true.
I think you're right
Don't kid yourself Jimmy. If a cow ever got the chance, he'd eat you and everyone you care about.
Your dog would kill you in a heartbeat if he thought he could
Which is unfortunate, since you would also slaughter your dog if you ever realize you can
Oh gods, no.... What have I done?
I mean, yeah?
I'm sure if I slipped and died in the shower my cats would eat me, and I'd eat them if it was between that and starvation
So why isn't that happening?
Are you letting a free meal loiter your hallways?
Killing the emergency rations now means they won't be fresh in an emergency!
Uh oh.
