I agree with golden oyster. I would recommend looking at multiple sources before consuming any mushroom. Mushrooms are very difficult to identify from an internet picture.
Yes, triple-checking everything you plan to eat is wise, as well as being cautious when you try a new species for the first time. You can have an allergy you don't know about, or a lack of enzymes necessary to process them safely (some species are "heavy" food).
It is possible to identify some species with good certainty, though, if the photos show all the key features. For Yellow Oysters, it's their yellow cap color discoloring whitish with age, growth in clusters on deciduous wood, concave fruitbodies with a lateral stipe, gills that run almost all the way down the stipe, and white spore print. There are no dangerous lookalikes with the same combination of features. Other oysters (mostly pretty similar but differently colored) are all edible, too.
There's also an app you can load on your phone called schroomify that's very helpful in mushroom identification.
I really recommend mushroomobserver.org for those who are seriously interested in learning to identify mushrooms. It's a bit oldschool compared to iNat and such, i.e. there is no AI image recognition or other gadgets there, but it has a very friendly and helpful community of truly qualified experts (including authors of many good books and field guides on North American mushrooms).
