When this thread started, I thought the "mold" sounded like sooty mold. Sooty mold does grow on "honeydew" from aphids or scale insects. It is harmless, except when it's thick enough to coat leaves and thereby reduce photosynthesis. Generally it is easy
to wash off, and getting rid of the insect problem gets rid of the fungus problem.

Of course, this could also be a slime mold: sometimes slime molds will climb up small shrubs and fruit on the branches. Also harmless, also easy to wash off.

Nina. Back from a plant pathology meeting with this advice: watch out for the police in Shepherdstown WV.
