Subject: Java fern black spots?

Hi all,

I was recently asked the following question:

I seem to have heard about this type of thing before but couldn't remember if
a cause had been decided on.  I had a quick search around on the net, and
didn't come up with anything.

Any clues??

Cheers,
    Len.
