Please send a photograph. It may be some kind of disease, but I can't tell from the brief description. Thanks.
Will do. Also this white paper stuff on trees and tables and other places including the house. Looks like paint if you didn't know the difference. Also on p v c joints in dark places.
The white material on piping and other non-biological material is likely not a fungus, as fungi need food to live, and they don't grow on such material. Looking forward of the photos from the tree.
