2 phenotypes of fruit, one tree

Asked August 14, 2018, 1:13 PM EDT

There are apples growing for the first time on an unknown species of fruit tree that also has a much smaller fruit. I’ve photos of both. I won’t speculate. Can you shed light?

This appears to be an apple tree with a bad case of cedar apple rust. The smaller fruits are just apples that the tree didn't have enough energy to develop because of the rust.

Here is some more information for you on the fungus:
