Parents tree has this orange spots on their leaves that looks like a fungus, they said they never noticed it there before. Should I tell them to cut the leaves with these orange spots, tell them to remove the tree, or use a fungicide?
They really like the tree and want to keep it. My plant app isn't correctly identifying the tree either I don't believe, and is inconsistent with it's identifications.
Ornamental Tree
That doesn't look like a typical fungus to me. Maybe a crown rust or something similar. I find the placement of them around the tree odd though.
It doesn't look like anything I have seen before. Several times I have run across odd looking growths on trees that reminded me of nothing I had seen before so I would google galls.
So I did and found this https://www.123rf.com/photo_92114542_twig-and-leaves-including-a-orange-plant-gall-in-natural-ambiance.html

Might be similar. You really need an ID to know how to treat it. Also an ID on the tree would help. Trees are not my thing. But if someone can ID your tree then google the tree's name with gall and see what comes up.

Okay thanks, I'll try to figure out what kind of tree it is, I'm kind of contemplating cutting it down though cuz I've been on a native kick the last few years, I could put something there that is from Michigan, whatever it is, it is really powdery so I hope it doesn't spread even though it's probably species-specific (hopefully).

Wait a bit and see if a more knowledgeable person stops by who has an answer to the tree's ID or what is on it.
Does your tree flower?
I just spent an hour googling orange rust galls. LOL I tell you very weird things grow on plants.

Looks like it is a buckthorn cultivar of some type, the photos here is very identical to the foliage, and the crown rust is affecting this leaves on this tree very similarly. Looks like there's not much you can do as the tree cannot be cured, you just have to keep cutting the leaves off every year that turn orange, fungicide only helps stop the amount of spores?

So it does look like crown rust. A lucky guess on my part though I would have gone with galls except all the galls I have seen before do not vary much on their host tree.
Don't you love google! You even got your tree ID.
