Without knowing the type of tree or seeing a photo, I can suggest these possibilities:




Also, some trees have bark containing Saponins, eucalyptus is one, which causes foam to form after a rain. It could run down into the leaves. It does not pose a problem.

If none of these seems like the problem, you may want to take a sample to a local nursery for identification.
