Based on the images you sent, my Plant ID app identifies all those trees as Bradford Pears.
I don't believe they are Bradford Pear trees??
Please send me an image of a leaf of the trees - Thank You!
Let me know if you would like another picture
Hello again Patricia,
First, thanks for the additional image. Come to find out that was also identified as a Bradford Pear. So my conclusion is that it is a Bradford Pear.
What you’re seeing: dead upper branches + fungus‑like growth on bark
A combination of:
Upper‑canopy dieback
Bark/branch fungal growth - Could also be lichens on the bark and branches
Multiple neighborhood trees showing the same issue
Most strongly aligns with canker diseases and structural decline, both of which are extremely common in Bradford pears.
Bradford pears are notorious for structural weakness, storm damage, and susceptibility to cankers. Once cankers girdle a branch, the branch dies back from that point upward.
Most likely diagnosis for a Bradford pear in Michigan. Canker disease (very likely) - Might be lichens, which are harmless
Cankers kill sections of bark and lead to dieback. Bradford pears are highly susceptible.
Structural failure + opportunistic fungi
Bradford pears often develop cracks, splits, and weak branch unions. Fungi then colonize the damaged wood.
Armillaria root rot (possible but less likely)
If you see mushrooms at the base or sheets of white mycelium under the bark, that makes it more likely.
