I have the same problem with my fukien tea,

No, you probably don't. Elm gets a disease, "Black spot" that is
unique to elms. That is probably what the original poster has,
unless his tree is indoors, in which case he probably has sooty mold.

Your fukien may have sooty mold: do you have aphids or scale insects?
Are parts of your tree sticky with honeydew? If so, a harmless black
fungus may be growing on the tree, and all you need to do is wash the
leaves. And, of course, deal with the insect problem.
