What is wrong with this Serviceberry?

Asked July 31, 2019, 12:39 PM EDT

Our client brought in this Serviceberry that has growths on it. She said the tree is about 7 years old and 8 ft tall. Not all of the berries have this and it has spread to her Quince as well. This started sometime last year but not as bad as this year. Thanks for you help.
