black mildew looking stuff???

Hi, I have black mildew looking marks on several leaves which started on our gumbo limbo trees. I sprayed at the beginning of Spring with no luck. I've recently seen that it has spread to any orchid close to the trees (and I grow outdoors)its also spread to palm tree leaves and turned them a dark brownish color through most of the leaves. If anyone knows what it may be, would Physan 20 help, its what I already have on hand... or is it something for an insecticide? Thanks for any help. AJ
I can email a pic if you need to see it on leaves... sorry, I couldn't figure out how to add the picture to this post.

Can you wipe the marks off?

Spray with Peroxide straight from the bottle. Transfer it just before spraying and throw away any left over. It will not harm they orchids.
