Expert Response
I believe your tree has a fungal condition, called anthracnose. Very common during cool wet weather. Typically, does not kill the tree and does not spread to nearby tree through root graft. No need to remove that tree to protect the other trees. Your tree will survive. Hope for warmer, drier weather! Here is a link to more information: https://extension.umn.edu/plant-diseases/apple-scab
