There's a process called certification you need to pass in order to release on a console where they test your game against a list of criteria outlined in the developer agreement to validate stability, minimum performance,and conformance with platform standards. Nintendo pioneered this process (the Nintendo seal of quality) in response to unauthorized developers releasing cartridges which ran poorly and could freeze or even cause damage to consoles.
For a while, console manufacturers pretty strict about certification requirements but as time goes on they've been granting more and more exceptions to large publishers willing to pay fees and pinky-promise to fix the issues post-launch.
They're pretty out of focus but it looks like a curtain crust Stereum sp.. The underside should be flat or slightly wrinkly without any gills, pores, or spines.
I had that same issue, what worked for me was manually removing the device which had been set up automatically because it had had been setup to only send jobs using the printer's hostname rather than its IP which my home router did not support.
Oyster mushrooms don't have rings and the gills tend to go nearly all the way down the stem. They also tend to grow on dead trees, not living ones like these.
Ah A. Ocreata is actually reported to have a poor taste. I'm not in Europe either but A. Phalloides is all over North America these days thanks to introduced hardwoods.
Most of the deaths are from East Asian immigrants mistakenly assuming the mushrooms here are like the ones at home, and they mis-identify and then harvest & eat the Amanita spp. instead of what they thought they were harvesting (I actually don't know the mushroom they mistake it for that is found in Asia).
I've heard this factoid is pretty exaggerated, it's not like East Asia doesn't have both deadly and edible Amanitas
I think that sticker just means you sent Nvidia a pre-release build so they had time to add game-specific hacks to their drivers before your launch.
