I was thinking perhaps  Botryosphaeria Canker?

My research so far leads me to believe that this is Botryosphaeria canker which is a common fungal disease of trees and woody shrubs, but it only attacks plants that are already stressed or weakened by other pathogens. Cankering can become quite extensive within the cambian layers, heartwood and inner bark of woody plants, cutting off the tissues that transport water and nutrients throughout the plant.

The disease starts in plans which are drought-stressed (we had drought in 2021) or stressed in others ways. (very wet conditions in 2022.) Joani Markey said the disease seems to occur in plants that have injury already. I researched this and found that canker generally enters through natural fissures or injury done to trees. I spoke with Joani 5-27-2022 morning and asked her to peel back the bark on the affected portion of the twigs portion to see what color is the wood. Red or dark brown would indicate canker fungus while white or greenish would indicate healthy wood.

In either case, my research indicates that the remedy is to prune a few inches back from the affected area and dispose of affected material. Fungal treatments are not recommended as the fungus is too deep for the treatment to reach it.
